Hamilton Pool Preserve Reviews

Return hike was moderately strenuous but since we were still wet from our swim we did not get overheated. I'm glad the number of visitors is limited. It was fun to swim under the hanging maiden hair ferns dripping water into the pool. We spotted turtles and catfish. Well worth the trip.

We were lucky that the swimming hole was open. It was a great day trip to beat the hot Texas summer. We plan to visit again next summer :)

Hamilton Pool is absolutely gorgeous! It is a short 1/4 mile from the parking lot. I highly recommend bringing shoes you can hike in/water shoes. It is a rocky hike and when you get to the pool area there are rocks all in the water. You definitely want something to protect your feet. Go in the waterfall, it's not too cold and exhilarating. Make sure you reserve a spot online and bring cash with you.

OMG, everyone must make a trip to Hamilton Pool. It's soooo beautiful.

During May and September, you need to make a reservation before going. You can choose between a morning slot; 9 am and 1 pm, or an afternoon slot; 2 pm to 5 pm.

It's a short 15 minute walk from the parking lot to Hamilton Pool. It's steep terrain, so wear good shoes.

There's a small beach to sun bath on or you can sit on the rocks around Hamilton Pool. The beach and the ground in the water are filled with stones so I suggest bringing some kind of bathing shoes to wear in the water.

We spent a good three hours there, walking around, swimming, sun bathing and having a picnic.

It's limited to about 60 people per slot, so it's never overcrowded.

There are no toilets once you get to Hamilton Pool itself, so make sure to use the ones by the parking lot.

Worth the wait. The "beach" is rocks/gravel. We had water shoes and that made a big difference. We had reservations for the first half of the day. Get there early & you've got your pick of spots on the beach.

Went on my last trip to Austin, it's about an hour by car from downtown Austin. The nice thing about was the pool itself and the formations of the rocks around the pool. I've been there on October 8th and I couldn't swim because of a bacteria that's being cleaned. Be sure to go early before 9 am because there's a limited quantity of people that can enter.

About 25 miles from Austin, the admission is 15 dollars per car unless you have someone in your car 62 or over then it is 5 dollars, this site for all ages however The trail to get there is pretty rocky, uneven, steep and wet in some places, but only .6 mile also has a beach / picnic area and a nice water fall and great rock formation most the time you are not allowed to swim due to heavy bacteria , so if you are a bit older use a stick to help you navigate the trail easier, and make sure all wear an athletic shoes, after you done with that area you could head back on the trail to the river about 1 mile with the same type of terrain. Enjoy the view and scenery.

Beautiful place to visit. I can’t describe the beauty. Life jackets are close to the water for anyone to borrow. Bring a snack, a towel, and a float. It gets deep. Tevas or Chacos are a good idea. And don’t forget a camera of some sort. Gorgeous. Don’t forget your reservation and cash for parking.

This is part of a state park. You pay to park. $15 per car, seniors and vets pay $5. From parking lot to the pool area is about 1/4 of a mile hike/walk. I must warn you that there are very steep steps and very narrow areas where the path goes. Lots of rocks. If you have any breathing and/ or physical impediment you can ask the park for help. No strollers allowed, no glass containers. The pool water is very clear and in Dec. the temperature of the water was 52 degrees. During the summer, it’s in the 60’s. On the other side of the pool and another .6 miles hike, again over steep steps and rugged paths, you will find a very beautiful view of the Pedernales River. Make sure you bring a bottle water. Please note there is 1 bathroom before you start the path and one before entering the pool area.

This place is awesome, must see for anyone in the area!! worth the trip/stop! Will be back again. The bacteria levels in the water were high when i visited (they won't let you in), so might be worth checking if you plan on getting into the water before going.

Great park! Recommend taking the path to the left first where the water is warmer and there is lots is beach. The grotto waterfall wasn’t running today. The hikes were beautiful however, I recommend getting there right at 9 when it opens or you might be waiting in line! No food for sale. NO PETS EVEN IF THEY ARE IN YOUR RV. NO EXCEPTIONS. You have to park at the Milton Reimers Ranch instead. It also has hiking trails but I didn’t do those on this trip.

This was my second time to visit Hamilton Pool, which is about 12 miles off of 71 near Lakeway and about a 40 minute drive from downtown Austin. The park charges $15 per car for admission. After a short hike down from the parking lot, you can go directly to the pool and the waterfall. This is an amazing geological formation with stalactites. As inviting as the water might be, it is rare, apparently, to be able to swim, as the water has unusually high levels of bacteria.

From the pool, one can walk down a path towards the Pedernales River and observe all sorts of geology, botany and even wildlife. I did see several folks swimming in the river. One piece of advice: Don't bring your pets, as no animals are allowed entry.

This was an amazing site. We went in Feb so unfortunetly we could not swim, but that ment less people hiking also. We got there right when it opened and were the first ones there. This is a beautiful spot and have recommended it to other people that have traveled to Austin and they have loved it also!

The whole hike was about 18 min in, some areas are a bit rocky, there was a bucket of walking sticks right at the beginning of the trail, so help yourself to one. It was all worth it, the scenery was stunning. . .

It took a bit of effort to get there and get parked but it was definitely worth it! So beautiful! The walk was easy for the kids, pack some water.

My son took me to this park and I was not disappointed. It can only be seen by reservation. That's great. This would get dangerously crowded before the reservation system. You can reserve for 9 AM to 1:Pm or for the afternoon. Do the morning, it really gets hot here in the summer. The hike to the pool was nice. It may be a little challenging for some. The pool itself is like nothing I have ever seen. I will let my pictures describe the place. This is a swimming area. You can visit the area without swimming and could see it all in a little over an hour. A must see!!!

Boy are we glad we found this place when searching for things to do in Austin. First, the view is every bit as postcard pretty as you see in the photos online. This is a reservation only county park, with time options of 9AM-1PM and 2PM-6PM. The cost is $ 11/car for up to six occupants (if reserving online), plus an additional $15 entrance fee. More if hauling a trailer. Cash only, so be ready to pay with cash.

A bit off the beaten path to get there, it doesn't look like much when arriving. A small guard gate greets you to verify your reservation time and provide a map for the pool and hiking. Tons of parking options close to the entrance. It is a 0.25 mile hike down to the pool, with the self-guided map pointing out numbers items of interest along the way. Once at the pool, there are many places to take great photos. An alternate 0.6 mile trail is available to go down to the Pedernales River. The trails are very rocky, and steep in parts, so bring your hiking boots (not flip-flops). It's well worth the extra time to hike all 1.75 miles of available trails.

We were notified a day before our visit that swimming would not be allowed due to high bacteria levels in the water. This was a major bummer, as swimming in the hole would have been simply awesome. But it didn't ruin this visit, and we were still very glad we took the time to come here.

Pets are NOT allowed, and life vests are available at the Hamilton Pool area for those who need. No lifeguard is duty, so act accordingly.

The reason for 2 stars is it should state on here that you must have reservations before you can enter the park, usually 3 weeks in advance. Wow. Really....we were traveling through and wanted to take pics but was refused. They should at least accommodate those who make the hour or so detour to see this, especially a group of retired veterans. I'm sure it's beautiful but again unaccommodating entry staff.

After reading several of those "top places/hidden beauty" lists on social media, we finally decided to gather a bunch of people and check it out for ourselves - you need to reserve well in advance, places fill up fast and they don't allow a particularly large number of people there at the one time (which is definitely a good thing). Its like $15 to reserve, and you reserve by vehicle not person. Don't be put off by the walk down - you park then walk down a trail to the "beach" / "pool" , whatever you wanna call it. Its not too bad, abit uneven, but hey, thats nature for ya.

The place is spectacular - it looks and feels almost tropical, it definitely doesn't feel like anywhere else in the united states !The pool has varying depth so be careful, it goes from shallow to deep pretty quickly!

Limiting numbers definitely helps the area not to be crowded, so there is plenty of space to lounge or swim.

Honestly, check it out. You'll be glad you did. There is not alot of shade on the beach, so remember sunscreen and maybe a hat (you can walk around the full circumference of the area, which involves inside the rock face with shade, but they filled up fast). Also, its a rocky "beach" and the rocks get hot! So id recommend flip flops or water shoes too.

nature at its best, you’ll want to take lots of pictures. reservations have to be made to get in, a lot of tough hiking for older people but it was so beautiful.

You have to have a reservation to visit which will be either morning or afternoon. Everyone is cleared out at the break time. If the bacteria level is high you may not swim. That was the case the day we had a reservation. The pool is not very large. Pretty to look at but not worth the trip on the day the bacteria level is too high.

You can truly disconnect on your visit to Hamilton Pool Preserve. It's a great spot to disconnect from the high-tech world, take a walk in the bush and just enjoy the tranquility. The pool itself is beautiful and the rock formations are amazing. You can swim, as long as there hasn't been recent rainfall. You do need to pre-book your time slot though, and the are fairly strict on when you need to leave, but that's a good thing as more people can enjoy this magical place.

Hamilton Pool is worth a visit. The creek, rock formations and the pool itself are beautiful and especially when it’s a cold or rainy day, one can enjoy some quiet time here. It seems to be very busy on warm days and during the weekends though. Please note that the fee (15 usd) can only be paid in cash or per check

Very relaxing. Must have reservations. You will need water shoes. Short hike. Babies are okay. It's a beautiful beach.

We were lucky it was a cold day so it was not overcrowded. This is a pleasant place to go with a nice path by the stream

This is a hidden gem that is well worth the 1/4 mile hike down a rather steep trail to it. But YOU MUST MAKE A RESERVATION to see it on the Travis County website. Then there is a $15.00 fee to park - but after going all through that and making the reservations, finding the place by GPS from where I was staying at Marble Falls, and hiking down - I could not believe the beauty of the pool and trail around the base of the overhang. You can only stay for 4 hours, but it was a very magical 4 hours for me. I visited in the morning from 9am to 1pm. There is another "slot" you can get from 2pm to 6pm. Since I traveled in February, it will too cold for swimming - so I thought, but several people did go in the pool - ah to be young and foolish again.... If you are planning a trip to this area, or planning a trip where you could have time to visit this wonderful natural attraction - please make a reservation and go - you will definitely not be sorry that you did.

We took the trip in February, no reservation needed. It is beautiful. It took less than 15 min. To walk down the path. Bring your camera. Not that we intended to swim in February, but the pool was closed due to high bacteria levels. I've heard it's not allowed to bring dogs there, might be worth checking out. The kids loved the trip too.

This is a bit out of the way, but between Fredricksburg and Austin, so along the way if you are heading between the two. There is little signage on the road to get there, FYI. The grotto (pool) and pathway from the pool to the Pedernales River is not long, but full of roots, uneven paths, and large rocks -- wouldn't be a great place for someone who is not sure footed. Take your time to enjoy the sensations: the scent of the evergreen, the sounds of the water dripping into the pond, the beauty of the grotto.

This is a very pretty spot with an easy hike into the waterfall and creek. Be sure to wear proper shoes as it is rocky and maybe slippery.

Beatyfull place! Nature at it's best, lovely walk going to the natures wonder. No bad things to remark about it.

MAKE SURE U MAKE RESERVATIONS!!! They charge by car so bring the biggest u got and load it up with people. But still it's very reasonable at 15 a car. This is truly a Texas gem. Beautiful overhang formation w dripping stalagtites. Waterfall was amazing. Things to bring: water shoes, it's a bit rocky so barefoot can be a bear! Maybe a yoga Matt to throw under ur towel for more comfortable relaxation time. Alcohol is ok as long as u don't flaunt it and keep ur beer in a coozy. A beach umbrella for summer days, there is not much shade on the "beach". The walk down is only a mild 1/4 mile so it wasn't bad to carry a small cooler. I would recommend to bring snacks also, there is no vending so if u stay the full allotted 4 hours u will be hungry.

The hike down to the pool preserve is 1/4 mile down stairs...so take that into account when taking a large ice chest. Make reservations early as scalpers have been a HUGE problem in 2018. I attempted to book in February for May reservations an every weekend was booked through July. I got in for my birthday and I booked back to back reservations. We had a great day. It was safe enough to leave our belongings down at the pool as you have to exit the park for an hour between 1 p.m.-2 p.m. I will make this an annual summer trip with my kids.

This place is so worth the entry fee and the hassle of making a reservation. A short hike takes you to a hidden lagoon that will take your breath away. On an especially hot and sunny day we were able to stay cool under the cavern and waterfalls. This is a unique experience, I wish I could go every weekend!

The water is clear and beautiful. The collapsed cavern is breathtaking. It is quite a hike to the preserve. They have also opened a trail that goes to Pedernales River. Be sure to plan your trip ahead of time, visits during certain dates are by reservation only. If you are traveling outside of reservation season, be sure to get their early, because they will turn people away if it gets too busy.

Hamilton Pool was a lot of fun! First of all, YOU NEED A RESERVATION! The reservation process was quick, cheap and easy (it’s the Travis County Parks website), though I did make them weeks in advance, and you need exact change in cash for the entrance / parking fee upon arrival ($15 when we went). We got there about an hour early and they don’t let you in, but there is another County park, Milton Reimers park, about a mile down the road that’s open, and they have real bathrooms, etc. The entrance fee to Reimers also applies to Hamilton Pool. We ended up going to MR after the pool as well to change clothes.

The preserve its self is prettier than I imagined with crystal clear water, a beautiful waterfall and a really cool cave-like dome over a portion of the pool. As others have reported, they have life jackets, but it would have been more fun with some floating things (noodle, rings, etc). Typical pool things like balls, rings, goggles aren’t really useful. Also, we had 2:00 pm reservations and the most fun we had was the first 30 minutes when we felt like we had the place to ourselves. By 4:00, the “beach” area was so packed you could hardly walk around. Also, there is no beach, there’s a rocky / gravely area cleared of vegetation. It’s tough on your feet!

One of the coolest aspects is that there is nothing else there! No concessions or little “improvements”. It’s like you and 100 of your closest friends discovered the coolest swimming hole in Texas. So bring everything you think you need. On a side note, I was there with 6 girls ranging in age from 11 -15, and ours were the only teenagers there. It was a very chill 20 something / adult crowd.

Don't forget to make a reservation online before you go! This place fills up by 9am and better be safe than sorry!

We came while visiting Austin after hearing this was a great place to visit. While it does provide a scenic setting, we were put off by the $26 fee ($15 entrance fee, $10 reservation fee, & $1 credit card fee) for what was offered. We walked to the pool where there were many people swimming, making it less than serene. We actually enjoyed the walk down to the Pedernoles River much more as it was a much more serene setting. Overall, still not worth the price during the reservation season.

The pool is a crystal blue color. Going under the rock formation, watching the water fall is breathtaking

unable to even view area.reservations needed.how do you get reservations ?? barricades and large staff at entrance.you are not getting in ?

Some friends and I made a reservation (mandatory) and forgot to call ahead to check on bacteria levels beforehand (I'd highly recommend doing so if you'f be disappointed by not swimming). Despite the pool being closed due to high levels of bacteria, we decided to go in and explore anyway. They do charge $15 (cash only) per vehicle. We parked and hiked the short (but steep- I'd definitely recommend water/hiking hybrid shoes) trail down to the pool. Even though we weren't able to swim, we did take some time to sit by the pool and admire all of the beauty. It was probably a blessing in disguise kind of thing, because it was incredibly peaceful being down there with only a handful of other people. We observed fish swimming around, with the sound of a gently cascading waterfall in the background. No crowds, no obnoxiousness, just peaceful tranquility, and beauty. We did the other hike on the back end to the Pedernales River, which was also a nice, easy .6 mile hike. One suggestion if you go on the hike to the river is mosquito protection, because we saw quite a few of them. If you want to beat the crowds and simply admire Mother Nature in her pristine beauty, then GO when the bacteria levels are high and just appreciate what the world has to offer!

The Pool is now accessible by reservation through the park system. There is poison ivy on the hiking trail into the Pool. Swimming is not often allowed due to farm runoff days and snakes. Good hike and pretty grotto.

This place is a spectacular natural beauty. It is a must see if you are near Austin. I visited last weekend. There were a couple of people swimming in the pool. I waded. It just always fed my spirit to be out in nature, God's creation. Another gem in Hill Country.

We went on a cool day and had no problem parking. It was a 15 minute walk mostly downhill and all the leaves were changing color. The scenery even walking up to it was stunning. We finally got the pool and could have sat there all day in awe. Absolutely worth the walk and drive out there!!

You must go here! I can't say enough about how amazing and beautiful it is. Gorgeous views, water, and wildlife. We didn't get to swim because the bacteria was too much, but it was still one of my favorite experiences.

We hadn’t been to Hamilton Pool in decades. It’s still gorgeous and extremely well protected by the County.

I recently visited Hamilton Pool with family from out-of-town. We wanted to show them the beauty of Texas Hill Country. Hamilton Pool did not disappoint. The pool is closed for swimming due to falling rocks and high bacteria, however, the hike is easy and pretty and the pool itself is beautiful. Reservations are required

Make a reservation on-line and you will not have any issues. 11.00 for the car up to 6 people. A 15.00 park entrance fee. It was a nice walk (a bit difficult if traveling with older people or small children). I would highly suggest swim shoes.

We went on a Sunday morning in early February so it was not crowded and a beautiful overcast day so not too hot. We were not brave enough to get in the water (about 68 degrees) but thoroughly enjoyed the natural beauty. It is a quarter mile hike from the parking lot and is steep so stones can be slippery so be careful. Prices are a little steep $11 reservation (REQUIRED) plus $15 at entrance but if they use those funds to return to native ecosystem I am ok to pay.

The pool was closed for swimming due to bacteria, but it turned to be an advantage. It was really quiet so we good enjoy the relaxing atmosphere and beautiful ambiance

Nice trail to go along with the pool itself. I recommend walking the trail down to the Pedernales River. Several benches along the trail for observing the wildlife and plants. Well shaded and easy terrain.

Visited this beauty last June 28. It was our second time as the first time we dropped by, we we're not allowed because we didn't have a reservation. The water was very inviting for swimming but we we're not allowed due to high level of bacteria. So it was pretty much just a tour. The way to the place have a nice shade of trees. I would have given this place a 5 if we we're able to swim so I just give it a 4..

This is a very special place, hidden and small enough I appreciate how well the park rangers take care of it. I don't think you will understand that this is a small body of water that if there is not enough water falling into it it can become unsafe and when you reserve your position it very clearly states this. Be patient, this is such a beautiful place but it definitely needs to be preserved. We loved it, it's an amazing experience.

We found this place in a national online publication that was appealing for daytrippers around the Hill Country of Texas.The day we found it,it was not a guided signed attraction with road directed intructions.Our google maps were all we could use to get there.Almost like a hidden secret that the state operates.Glad we did find it because it was an unforgettable place to visit & well worth the short hike ,but not for the physically challenged.It takes some agility & energy to navigate the trail that gets you there.On a spring day at the end of March the wait was not long(maybe 15 to 30 minutes) but there was no turning back for us because we may never pass this way again.Quite a site but no swimming allowed on this day because of health concerns or bacteria levels is what we were told.

We were *lucky* enough to be in Austin when it got a rare snow. I understand that often reservations are required but the poor weather allowed us to have the pool to ourselves. The hike to the pool was lovely and the pool itself was other-worldly. Highly recommend!

A pleasant surprise. I thought it was going to be a total tourist cheesy thing to do but I was surprised. The walk to the river and pool was beautiful, great mild hike / walk . It was a great couples activity. No crowds when we went on a Wednesday. Drive was easy and beautiful! Good picture spot

Paid a visit here on a sunny October afternoon.

Fairly steep descent on rocks and gravel but well worth it. The pool is stunningly beautiful and the walkway to the river (opposite direction to the pool) is so tranquil and scenic. Fantastic photo opportunities and in places it looked like the set from Avatar.
Highly recommended - just take it slow on the ascent back as it's quite punishing in the heat.

I'm not an outdoors kinda person and I loved it. Beautiful and gods true creation can only leave you amazed and wanting to see again

Must knows/tips:
-reservations are a MUST and are non refundable approx $12 online thru Travis county parks website (they ask the number of people max 8)
-reservations are in 4hr blocks. AM or PM (2-6pm) but they start having you clear out 30 min prior
-$15 dollars to park, cash or local check only
-approx .25 mile hike some what steep with rocks
-must take your own water and snacks
-recommend an ice chest you can carry and a blanket. ( the less you carry the better)
-there is a shuttle for those who can not hike the distance but regardless you will have to walk some
-there are restrooms and Porto potties on premises (recommend you go before you hike down)
-hike around the entire pool, it's not long, nice views, there is a very short and narrow passage and stairs to climb
-no pets allowed
-you can not display or show alcoholic drinks ( you need to put them in a cup or have a koozie)
-no glass
- you can take floats
- they have life vests
-water is deep but if you plan on hanging around the sides or shallower water, take some type of water shoe. It's all rock
-there are large catfish swimming along the edge

This was literally my favorite part of the trip. I booked ahead for a spot as well. I can't believe this is all naturally formed. The photos do not do it justice. Even when you stand there in person it does not feel real. It is so beautiful! The water is so clean and the trail going down to the area is not far either. Next time I am in Texas I am coming back. This place definitely has my heart.

After I came home I liked a bunch of stuff about Austin on instagram and I saw that people wanted to build an RV park here. I was so upset! I signed the petition and wrote to people that are involved in the government. If you care about this beautiful area and do not want it to get destroyed go to friendsofhamiltonpool on instagram! or visit www.savehamiltonpool.org SPREAD THE WORD AND SAVE NATURE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Now that Hamilton has instituted an online reservation system, good luck ever visiting in the summer unless you play your trip months in advance.

They've also bumped the price up to $11 for a reservation, then an extra $15 entry fee per car. For $26, you can find better or cheaper places.

The water can be pretty, but it's often muddier than the pictures would lead you to believe. And that's only IF you can swim -- the pool is constantly being closed due to high bacteria count. Try Barton Springs or Blue Hole instead!

We couldn't go in the water due to high bacteria. But it was well worth visiting. Get there early though, because this place fills up fast!

This place is gorgeous, but as soon as we got there we saw a few big black snakes. I was kind of afraid to swim after that, but I did anyway. Water was a bit cold for me. I recommend making a reservation online if you go, it was very crowded when I was there and it was in the morning on a work day.

The clear waters, the waterfalls, the cleanliness, the catfish swimming at your feet! This place is a must see. Yes you need a reservation but it's good concept too. Keeps it enjoyable not overcrowded. Pop a towel down and enjoy for a few hours!

Loved this place and their veterans discount. They also take good care of it and had a park ranger watch it, as well as life jacket available on site. Unfortunately the longer trail was close to public that day. But still worth the drive.

I came here during the winter chill. Although only around 55 degrees, it was still my favorite part of my trip to Austin. Worth the 45 min drive! This place is absolutely beautiful. For those not able to walk so far, the actual Hamilton pool is just a short walk from the parking lot. There is another hiking trail that follows the river- I would highly recommend! It took us (college kids) about 1 hour, but we were also very slow- pausing to take pictures and goof around. The trails are very easy and nice, mostly packed down dirt, although there were some parts that were a bit rocky, but never strenuous. The water is so clear, yet still a bright aqua color- amazing! I would definitely come back in the summer for a quick dip, although some of my friends were crazy enough to jump in (twice!) to the pool when the water was only 47! Heads up- to get into the park is $15 per car, and we paid in cash, although I'm not sure if they take a credit card or not.

It's beautiful and super refreshing! It was well worth booking in advance and paying to enter the park. There are preservation fees per car and per person, but the place is super beautiful and well maintained.

Was the best trip we ever made. We loved the hike to the pool and it was amazing. We swam in it. Hiked around the cave of it. All I can say is God is a true artist!!

Brings back great memories of UT in the spring 1963-1968. The grass hillside was covered with kids enjoying Spring cold fresh water and beauty of the Austin Hill Country.
Great time and wonderful experiences, all a part of the UT education.

Is not worth a visit but wasted time. We were very disappointed with the Hamilton pool. It's too much money to enter and a parking fee to see a murky yellow-green lake with three catfishes. The way there is dangerous and not comfortable. You have to be able to walk well and especially put on sturdy shoes or sneakers. You can save yourself!

If you are visiting the Austin area (or even San Antonio), *DO* make time to drive to this "hidden" gem!! We were fortunate to have a BEAUTIFUL day, in early December, so no reservations needed - just drove right in, threw on our Merrill hiking shoes (recommended...flip-flops, not so much, unless you like ankle sprains) and headed down the trail to a STUNNING sight. Be sure to make a "left-turn", and head over to the "river pinnacle", as well..... oh, and be sure to carry some crackers or grapes.....you'll figure out why, when you get to the river. Happy trails!!

I was a bit wary reading the reviews, thinking maybe I wouldn't be able to hike down the trail from the carpark, but was pleasantly surprised. The trail is steep for a little way, but is very well maintained into large rocky steps. Two seating areas are spaced along the track for a breather on the way back up. I am very overweight, with a twinge in the knee, but still made it down and back up without trouble. A little scary were the steep metal stairs down into the overhanging cave, which were wet from dripping overhead. Well worth the effort, it's a beautiful spot. We arrived before 10am in late November during the week, so only saw 3 or 4 other people, plus some rangers. A crowd would spoil the serenity, and I think it's a wise move to restrict numbers.

Make sure you have reservations when required. An easy hike down and back and worth every step. We visited on a cool, rainy day but the beauty of this place made it worth it. Water in March was around 64 but clear and the fish were easily visible while wading. Just a spectacular piece of nautre!

First let me say that we were there in November, and with the lack of rainfall in Texas this year, there was no waterfall. I'm sure it's very picturesque during the rainy season but not when we were there. The pool was nothing to write home about. The river trail was enjoyable and had nice views.
Reservations are needed to enter the Preserve. Make the reservation online; it's easy and it costs $11. Once you get there you'll need to pay another $6/person, cash.
If i had driven out to this place I would have felt disappointed, but it was on our way from Austin to San Antonio, so no regrets.

The hike was a bit more strenuous than I expected, but not really bad. We went to the pool (where swimming was allowed that day) and enjoyed the beautiful spot. There is a grotto to walk through, and it was a completely new experience for me. A few birds along the way, lots of bald cypress trees, interesting limestone rock formations, and pretty little creek through the bottom of the canyon. We hiked to the pool first, and then hiked in the opposite direction to the Pedernales River. Well worth the effort, and VERY glad it was a comfortable 60 degrees out. I would not do it in the heat.

If you love the sound of a nice waterfall then you will really enjoy this place! The hike was an easy one but there are some steps if you choose to climb down to the waterfall. It is worth it to go down and walk all the way around the inside. You can take some amazing photos and leave all your stress there when you hike out! Certain times of the year require a reservation so plan ahead! This place is very peaceful and you won't be disappointed!

A nice walk on a nice day but considering you can no longer swim here or take the path around the pool not worth the money paid. However, The guide at the pool was very friendly and knowledgeable.

I made the mistake of traveling to Hamilton Pool a year ago without making a reservation. This year, I made a reservation a month in advance and was able to visit the pool. It's worth every step and gorgeous! Its a spectacular natural pool with a little hiking to get to. I would advise to make your reservation from 12-3pm in that specific time slot so more sunshine!

We loved stopping here on our way home from an anniversary trip to Fredericksburg. Simply beautiful and the weather couldn't have been better. Must do! We will be back for sure. We weren't able to swim due to bacteria.

We kept putting off going to Hamilton Pool because it used to be really hard to get in unless you got there really early and waited in line. Now they require reservations (online) and they only allow a certain number of people in at a time. Make your reservation ASAP because they fill up fast - even if you have to schedule way in the future, do it. You don't want to miss seeing this in person. Wear tennis shoes and carry water because it's a little bit of a hike in and out of the place. Bring a towel or something to sit on. The one thing I didn't think about that I will definitely carry with me next time is a small tube to float on in the water because the entire pool is deep water. That's all I can think of that you need to know from me- check their website for other important info. I'm attaching pics but they do not even begin to show how awesome this place is in person.

We went on a weekday in winter which was great because there was nobody there. Obviously too cold to swim though. I was a little annoyed that even though the river trail was closed we were still charged full price. Thankfully when we asked what else there was to do we were informed of raimer ranch just down the road that had hiking that our pass would cover.

We started walking down some steps made of logs and some uneven big rocks. We got about half way down and my wife had to go back. She was having hip problems on this trip and her balance ain't what it use to be. But I made it down there, beautiful scenery by a creek and then the big pool with little water fall coming over the edge. By the waterfall is another bit of a challenge if you want to walk all the way around the pool, you go up on some big rocks. Worth the hike if you can do it. I will walk over anything as long as it's not along the edge of a cliff. That's where I draw the line. There is no cliff here to fall off of, but some uneven footing bad for the un-mountaingoat type people.

We reserved in June, didn't go until September but it was so very worth the wait! So beautiful. Large catfish were pretty bold in the shallow waters. I would recommend water shoes. We can't wait to go again. The hike down was great too. I wouldn't recommend a stroller. A baby carrier for sure and maybe some beach chairs with straps. We brought a small cooler with some beer and coozies. They don't want visible alcohol. It was a very family friendly environment.

Great Place if you can get in when the water is open. They now also require reservations so be sure to check far in Advance as planning is more critical now

This place is absolutely beautiful and secluded!!! Hamilton Pool has beautiful pools, a large cavern, and beautiful trials! It's just gorgeous! The main pool is the natural spring preserve that Hamilton Pool is know for. However there is another trial that takes you on a 25 minute hike to the the river, definitely worth the hike!
The pool is refreshingly cool with crystal clear water! So clear you can see the fish in the water (of course when people start to stir the water it will get less clear). Its just amazing!

THINGS TO REMEMBER PRIOR TO GOING:
Dont forget to reserve your time well ahead of time, at least a few weeks ahead of time.

You'll need to pay $11 to make the reservation online and $15 to get into the park, Cash only, so bring cash! It's all well worth it

Bring cash for the entrance fee and pack chairs/food and drinks (The picnic tables are only located near the parking lot

Wear good water shoes (you'll need them for the rocky bottom pool)

We arrived at the Hamilton Pool just at sunset. The light glimmering through the trees, the sparkling effervescence of the falls, and the soothing sound of water dripping into the pool, made it seem like we had left the world. Entranced, we stood and watched until last light of day had dimmed below the horizon.

Make sure you have a reservation, which you can do on line. Only bring what you can carry. People with limited mobility would struggle with the half mile trek down to the pool you may want to bring a walking stick. It was beautiful, if you are not a strong swimmer than I would strongly advise brining some kind of floatation vest, pool noodle or tube.

Get there early if you don't have a reservation as they have limited spots and only let you in as people leave. $15.00 a vehicle or $5.00 if you are a senior! 😊 Wear your tennis shoes. Easy hike down and back. Beautiful!

Great short hike that even active toddlers can handle. It was slightly longer during our hike because we had to walk back all around the pool, the tiny bridge that makes it a loop was closed. High bacteria during our visit but the park ranger said it should reopen for swimming in late Spring. Bring water it gets hot and there are no water fountains (but plenty of bathrooms with purell)

Beautiful place to hike and swim. One of the most popular places in the area. Must have reservations May-September to get n. It is worth it.

First and foremost MAKE THE RESERVATION 3-6 in advance!! Something I didn’t realize was the trail there which is .25 of mile is rugged. There and back. Totally worth it but for some it might be difficult. The sight was just beautiful! I wish I could have gotten in the water but I had falling off my bike the dAy before and had an open scrap so I didn’t get in. There are fish that swim right there beside you and amazing shade of course and the water felt (with my hands) nice.

To get to Hamilton Pool, there is about a 30 minute hike. Wear tennis shoes, I don't recommend sandals or flip-flops.You will need to make a reservation as they limit the number of people there at one time. Bring a towel or blanket for relaxing on the beach. We brought snacks and bottled water as well. When you buy a pass to Hamilton Pool the same pass will get you into other parks in the area on the same day. It is a wonderful day trip!!!

We weren't expecting much but this is hidden gem. At gate, we were told about 45 mins waiting time but it took only 15 mins to pass the line and park. After parking it would take 10-15 mins to walk the trail to reach the pool. This place has amazing views.

So i drove out here on a Saturday not realizing you needed a reservation now. They were booked the entire weekend and offered up an apology but it was a bit frustrating in the way they handle things out here. Definitely set up for locals who know the rules. Book in advance via the county website. All i got to see was the sign and a check in gate... thanks for the drive.

Short hike to pool. It is lovely . There is a beach which is mostly in the sun . The other side is shaded.

Wear water shoes. Very rocky and slippery.

This is definitely a "must-visit" site in Texas! The trail down was definitely steep, but completely hike-able, and the payoff at the end is just incredible. The trail extends around the pool, under the limestone ledge, making for some amazing views of the collapsed cavern. We went in the fall and the pool was closed for swimming due to high bacterial levels, but I still felt like the hike and the view were were more than the cost of admission. We also took the river hike (a little over a mile round trip) to the Perdenales River... definitely worth the effort!

A bit of a drive from San Antonio but the outdoor activity was worth it. We were there off season so there was no issue with parking. Hamilton Pool is a short hike with a beautiful blue pool at the end. They provide life jackets for swimmers. The trail around the pool gives you a different perspective from each angle. There are waterfalls, however, water was not plentiful on the day of our visit. The longer trail is to the river, it was a bit more strenuous than the pool with a nice river view at the end. It was a pleasant afternoon.

A must see!! I was trying to visit this place for a while now but could never get a reservation. As soon as I got the news that reservations are no longer needed ( am not sure if it's temporary) we drove up very early to make sure we get in. Absolutely amazing and beautiful Texas gem , totally worth waiting for. Bring water proof camera and water shoes! Prepare to hike and bring water.

Definitely spend the extra time and hike both sides of the trail. The view of the river is really cool and worth the 0.6 miles (one-way).

Wonderful place! It's definitely worth the drive. Make your reservation in advance as they do sell out especially in the summer. I think the price is very reasonable since this place is very well kept. The trail leading down to the pool is not a bad walk; I brought my parents (in their 60's) and they didn't have any problem. Definitely bring some snacks/drinks, blankets, towels, & floats. The water was pretty chilly but it felt amazing when we visited in June.

Enjoyed the short trek down to the pool on a warm spring day! You can no longer walk under the overhang due to falling rocks but the view from the shore is breathtaking. Make sure you make a reservation before you go as it is required and space is limited!

The place is probably pretty enough, but didn't live up to the hype. It is crowded, rocky getting in, and the water is murky. The trail to the pool moves at the speed of the slowest person in front of you. You have to reserve in advance then pay another $15 upon arrival. Not something I'd ever do again.

Be ready for a long walk to the swimming hole. However, it's long worth it. Photos can be found everywhere as this is a place many people want to visit as an outdoor activity in the Austin area. It is a natural beauty.

Stunning area. It is a very easy hike to get to the pool, most should be able to do it. Totally worth it! It is definitely one of the most beautiful places i’ve ever been to, and not what you expect to be found in the area! Be sure to make reservations in advance as it sells out fairly quickly! I like that have visitation by reservation only as it keeps the crowd down and you’re able to enjoy the view better.

Visited with my two 13 year olds and my 11 year old. Beautiful scenery, but not a lot to do. Very small seating area. Walk down to swimming area was not too difficult for us, but would be kinda long if you are carrying coolers, chairs etc. we spent a total of about 2 hours there and we were ready to go. It was great to do once, but not sure we would go again. We made reservations months in advance.

We arrived 30 mins prior to our scheduled time and the park ranger will not allow you to wait on the road. So we went to Milton Reimer Park just down the road and waited there. If you pay to park at Reimer, they will discount the parking at Hamilton pool. It’s a $5.00 difference. So while we waited we checked out Reimer Park. Once our time to check in was up, we drove to the pool. They do verify that you do have a reservation via electronically means. There isn’t a lot of parking. Probably one of the reasons you have to have a reservation to get in.
It’s 1/4 mile hike to the pool from the roadway. If your carrying a heavy cooler in the summer, just know you will be taking breaks on the pathway. There is no trash cans by the pool itself. You must take all items back to the car area. So be prepared.
The pool itself is beautiful. My kids enjoyed the friendly catfish and trout. They come within inches of you to swim. Of course it does get a bit crowded. There was a group of kids who began throwing rocks. Apparently those parents didn’t know how to parent. Throwing rocks when it’s crowded is a mistake and an accident waiting to happen.
Other than that, kids and I can’t wait to go back.

We love the hiked to the river. We recommend doing that first. The kids loved climbing the terrain. Hamilton Pool was chilly but beautiful.

My husband and I took a 5 day trip to the Hill Country/Austin/San Antonio areas last week and this was our favorite part of the trip. Whether you like nature or not, this place us utterly stunning.

According to the park ranger that happened to stop by the pool and talk to us while we were there, in the spring/summer/fall this place is crazy so if you are visiting then, get there before open! And expect about 300 other people to be there too.

But in the winter - WOW. We were two of about 15-20 people there so it seemed like we were alone. The water was only 50 degrees so far too cold to swim, but we didn't even care; it was so pretty to look at it was still worth the trip. The hike down to the pool was really short (about .5 miles) and there were plenty of stairs made available so I wouldn't worry about the age of the visitor; it's friendly for all.

BUT...don't go off the path! This area is home to 5 venomous species of snakes, which stay off the well traveled areas but do frequent the stream that you'll walk by to get to the pool, and are in the non-pathed areas of the park.

Love love love this place and it is a MUST SEE if you are in the Hill Country, Austin or San Antonio area.

It's quite a sight! Do go early as there is a limit of how many people are allowed in at a time. Go under the waterfall it's the best part!

Definitely worth checking out, it makes for a fun day trip! Unfortunately we couldn't swim this day as there were high levels of bacteria in the water, but still a cool sight to see. We packed a lunch and had an awesome view.

You have to make reservations ahead of time and pick a time slot to visit. Enjoyed the hike and with the control of hikers it was nice and not too crowded. It was a little cool still so no swimming. We followed the hike to a brewery close by for some local beer. Great afternoon.

We seriously loved the Riverwalk. So peaceful and quiet, Went to the pool as well and it was beautiful but crowded. A must do in Texas!

Definitely wear walking shoes ..nature at its best.. they do offer walking sticks if needed..call in advance if planning to swim. Sometimes water not safe to swim.

If you want to take a break from your schedule, this is a must stop! Be sure to take your hiking shoes and your swimsuit. You have to walk down a rocky path to get to the pool, but when you finally get there you will see one of the most amazing sites! You can lounge at the edge of the water or swim in some of the purest water you will ever have the chance to swim in. I highly recommend Hamilton Pool for couples or the family!

I can see why the reservations are so scarce here. We went down and looked at the pool which was beautiful, but we could not swim due to high bacteria levels. It was thus a little underwhelming especially considering we paid 30 dollars. There was a nice hike though too so perhaps so consolation.

Let me start off by saying that we were not able to get in the pool because of high bacteria levels in the water. The pool has basically been off limits for swimming almost this whole summer as I had some friends go earlier in the year. Either way it is a great place for hiking and scenery. You can take great photos. If you are taking the trail down to the pool it is not too hard if you have kids. I have a toddler and was a little worried about going down but it wasn't bad at all. Take your own water as they did not have any there or any kind of shops. Also be prepared with sunscreen and comforrable shoes.

Visited in Fall when crowds aren't as large. Fairly limited parking, so make a reservation. An easy hike to the grotto. Very pretty and cooler in the shade, but bacteria counts were too high to allow swimming. This place is probably fairly unique in Texas, but not so much so for those from states with more rain and forests.

This is such an amazing place, however before going you must know a few things so you'll be able to enjoy the experience more:
- Reserve ahead of time, like a few weeks ahead of time. The only time available for my sister and I was 9 am on a Tuesday, we had to be at the airport at 10:30 but we reserved it anyway. It was totally worth the risk. (We weren't even late to the airport)
- Wear proper shoes, it can be slippery and steep at parts. You're hiking for only a 1/4 mile, but it's more than just an average walking trail. You're walking on rocks and uneven ground.
-Even if you aren't allowed to swim due to rain, still go! It's still worth it so beautiful.

I wish I was able to stay longer but I'm still super happy I was able to see it and experience it. Such an amazing spot, if you love nature this is a must see.

Side note: The pics are beautiful but in person is a thousand times better.

This was a disappointment for sure. Paying to reserve your time slot and then paying to enter the park was simply not worth it. The actual "pool" was a very quick hike to get to. It was nice to look at, the birds flying around were cool, and the big fish swimming around were interesting, but then what? With so swimming allowed it was just sort of quick and boring. On our way down to the pool the hike to the river had been closed, that was annoying as well. When we decided to leave the pool the hike to the river had opened up. The relatively quick hike down to the river was nice and easy (all of the hiking was easy). The river was beautiful. You felt alone in the middle of nowhere. Only a few other visitors seemed to make the trek down to the river. It was a nice place to lay out for a bit. The only problem with that is there is another park close by that you don't need to pay to reserve your time, it's cheaper to enter the park, and you can get to the same river. Overall this was a bummer of a trip.

We had some time and the weather was beautiful so we decided to ride out to Dripping Springs. The ride there was nice, lots of Hill Country scenery. It cost $15 for the car to get into the Preserve. The parking lot is fairly small, so it limits the number of people who can get in (a good thing!) The pool itself was closed because of bacteria, but it was really not warm enough to swim anyway.
The path to the pool is about 1/4 mile over fairly rough terrain. The pool itself was beautiful. It was a nice afternoon in the country!

Had a great time here hiking the trails and visiting the pool and waterfall. Only disappointment was that the bacteria was too high to swim and that it cost $15 per car to enter the park.

One of the most amazing places I've seen. Spent the morning there with my teenage dauighter and she kept saying how much she loved it. Its quite spectacular. Space is limited so it never gets crowded. You have to book ahead but its worth it. We went there first thing in the morning so the water was clear. if you're in the area,it is a must see

Our local hosts had never been and suggested we all visit this place based on word-of-mouth. There was a ‘little’ hike to the Perdernales river and then the Pool. Be warned that the little hike is moderately difficult but the greatest surprise. The narrow single path trail followed the stream from the Pool to the river and had towering bald cypress trees that had to be centuries old. Delightful and unexpected. You could imagine native Americans centuries ago living along the stream.

Very cool place- get there early and buy your tickets online. It's an attraction and doesn't feel like you are in Texas at all!

Good short-walk (0.6mi) with a great reward. It's hard to believe you are still in texas. We enjoyed the view from the lollipop loop around the oasis. Unfortunately, there was high concentration of bacteria in the water, so we could not swim, so we hiked instead. we went to Pedernales River cutt off wich was about 3/4 of a mile down and do some swimming there. Not as great of a view as the pool though. We heard is common for them to close the oasis for swimming during the rainy season in c-tx. so be prepared with a plan B and check the status of the park before heading there as they would be close if there is rain the night before.

Pay $15 dollars, park and hike down to the pool. It's a rocky, twisty path, so wear an athletic shoe and take your time. You don't want to fall or twist your ankle, etc. You have to hike down quite a ways and you'll wonder how much further, especially since you can hear the water fall. Eventually the pool will come into view. It's big! And the waterfall makes it magical. The water is a pristine bright green shade, but no swimming was allowed on the day we visited due to "a high level of bacteria" caused by agricultural runoff. Despite this, it's so lovely, definetly a great spot to propose or get engaged. Along the way enjoy trees and foliage. Gentle maidenhair ferns line the rim of the location and grow off the rocks. It takes a very special environment to grow these so, very special. Certainly a sight and experience well worth the trek. By moonlight it must be so amazing. The hike back up is steep and not short so take your time.

Went in November when you do not need a reservation. Beautiful walk to the natural pool and river.
You can swim and enjoy the beauty.

Absolutely gorgeous natural pool. The Park Service has strict rules & regulations, please read them beforehand. It is reservation only to minimize the number of visitors. They will not make exceptions or refunds. There is no guarantee that swimming will be allowed. The day we visited high bacteria levels kept the swimming area closed. The scenery is well worth the visit though. It is a must see.

My family went to Hamilton Pool for Mother's Day. It's gorgeous and awesome and fun and you should definitely go there.
Reservations are required in the warmer months, and you will be happy that the number of visitors is limited. The "beach" area is small.
I foolishly thought that the reservation fee was also the entrance fee. This is not the case. Even though you pay $11 to make your reservation you still need to bring $15 cash for the entrance fee. This realization has us scrounging for change in the car to find another dollar.....but it all worked out.
Worth the drive, very lovely spot, bring cash.

Reservations were a must 9-1 or 2-6, $15 entry fee per vehicle worth every penny! Short trail with an amazing end!

This is a cool park with an easy hike to the waterfall. Very picturesque with lots if photo OPs! Bacteria in water kept us from swimming but still worth the visit. $15 per car fee.

I've always heard of this grotto but never visited. We went on a warm day in January and there were very few people there. It's wonderful to look at and walk around. We also hiked the other trail along the river. All of the park is well maintained. Had a great afternoon.

Me and my wife visited this place in late December. Though it was a bit cold, but it was not too bad for the little hike to this place. The hike was easy. And it presented us to this magnificent pool. I heard before that it's not as beautiful as it seems in picture; but to me it was actually quite treat to the eyes. You have to go all the way back of the pool. It's a small loop. Just be careful because it might be slippery. A must visit if you are near Austin.

My family and I drove from Louisiana to visit the Hamilton Pool Preserve and were not disappointed. It was one of the coolest places I've been. We were kind of sad about not being able to swim due to bacteria in the water but after we got there the disappointment went away. We were just glad it was still open to tour because it is stunning and soooo worth the drive! In case others need to know, there is a small little hike there and a few steep steps to go down. We managed fine even with a 2 year old but just wanted to throw that out there for those who need to know. We can't wait to go back and visit again!!

We have been wanting to see Hamilton Pool for so long and finally made it this month. It is so beautiful! No swimming was allowed and apparently this makes it clearer and less crowded for great photos. We swam in the Pedernales River nearby so that was fine.

Cheryl and John our great friends from St Louis and Carol and me from UK decided it would be a great idea to visit this beautiful place on our recent visit to Texas so Cheryl duly did her homework and visited various web sites to wisely prepare...................no literature or media source informed us that you had to "preserve" before rocking up, in fact the first notice we had about "preserving" was a brown tourist sign as we left Dripping Springs a few miles away from the site. The location is in the middle of nowhere and apart from the few cars parked up there was no sign of life, but did the lady on the gate allow us to pay some money and at least have a walk down the trail.......NO she didn't! Rules are rules she said and whilst that is correct I feel some leeway could have been given. Astonishing!

Love this place but we didn’t get to swim this time around because of the bacteria levels. With the new reservation system you have to lock into a date and pray for the waters to clear to allow for swimming. It’s still worth seeing. But not as accessible as a swimming hole as it once was.

My extended family and myself visited Hamilton Pool a couple of weeks ago. The pool itself is very pretty and perfect way to cool off on a hot day. However, we overpacked for the hike down and back up (we packed chairs and an ice chest packed with food and water-we typically go to the beach with this kind of stuff). Don't make the mistake that we did because the climb up is much more challenging than coming down. I would recommend that each person take their own backpack for their towel & bottle of water...that's all that you need (maybe a small snack if you have kids). Also, the website said no floaties but there were people with pool noodles, kick boards, floats & kids with floaties (the ones with the chest strap). They do offer all different sizes of life vests for all ages & sizes (except infants) for free but there are limited supplies. I would recommend a life vest for kids and anyone that isn't a confident swimmer. It's at least 25 feet deep in most parts of the pool. It does have a gradual beach area (very pebbly so water shoes are also recommended but not necessary) that is about ankle deep and goes to about 4 feet before it completely drops off. The beach area to sit is VERY small so don't expect to have lots of room during peak season. There are also port-o-potties should you need to use the facilities while at the pool. Reservations are also required and I recommend that you book early in advance to guarantee your preferred day. I enjoyed it but not sure I would go out of my way to go again in the future.

Really busy on weekends,reservations only to get from March on.
Several movies have been filmed here,beautiful place,great rope swing,good hilly path from parking lot to the water,lots of wildlife to seeif you get there early enough

I saw Hamilton pool preserve in a travel blog. The picture stayed with me for months and when I finally made it to Austin, I knew this was the place to go! Beware that you must make a reservation prior to coming (they fill up fast) so make sure you book atleast 1 week before, if not more In the summer.

I went in January it was about 50 degrees, so no swimming but the hike was still beautiful. It was a peaceful break from the city of Austin. I also enjoyed the 30-40 min drive. Lots of winding roads and a nice view of Texas countryside. There are many wineries on the way back/ nearby to add to your trek!

All in all, we spent 1 hr 20 min at the park, walking, taking pictures and just sitting down to enjoy the beauty. I can imagine that In the summer you could spend many more hours here, though! Highly recommend if you’re in austin!! The pictures don’t even do it justice but I’ll try...

I just moved to Austin 3 months ago because my husband is from here, so every weekend he lets me choose a destination to go. The last weekend in April I chose the Hamilton Pool. We were there when the park opened up in the morning as I read it's always very busy and we wanted to have a quiet time there. You've to walk down a little hill with lots of stones so make sure you put on walking shoes. As soon as you walk over the bridge you'll be amazed by this lovely spot! Everyone who has been to Mexico will see it is like a Mexican Cenote. A special cave with natural underground water tubes. The water is super clear and cold of course. You'll see a waterfall in front and lots of stalactites hanging down the roof, built by that cave water over all those years. As we were visiting so early not much people were there so we could enjoy our "us-time", you can sit on the beach or go inside the cave, look for a comfy spot on the rocks and just sit there and enjoy the silence, listening to the music of the waterfall. I love being in the nature, so far I've seen a lot of the Texas beauty already and even there's much more to explore about this wonderful State, the Hamilton Pool will be always one of my favorite spots to visit.

What a spectacular natural texas wonder. Plan to spend a few hours here. The hike is rather short and is well maintained. Prepare for crowds and make sure to have a reservation.

Such a great experience! Would definitely recommend going again. Make sure to purchase a spot in advance and have cash when you get there. There are a couple of hiking trails that are very family friendly. Our 5 and 7 year old were able to participate fully. The pool is breathtaking and very worth the entry free.

Went in a group hike with our friend and our kids. My daughter is 4 years old and she was able to complete the hike without a problem. It rained the night before, so the pool was full and the waterfall gushing. Recommend if you're in the area, parking was kinda expensive but still a great time to do something active.

Well worth a visit. Beautiful. Book in advance!! Rocky uneven path down to the pool but definitely worth the trek!!!

I wish there was a way to prorate it when the trails are closed. Still gorgeous and still glad we came just sad we couldn't see all that there is to offer.

Beautiful place! You have to make a reservation several weeks in advance (about $12). Parking is $15. Only one car per reservation. It's a semi-steep rocky .25 mile walk downhill to the water. Harder going up of course but so worth it. Wear tennis shoes for the walk. ***Bring water shoes for the water bc the beach is very pebbly and hurts like hell. The water was a little chilly going in, but you get used to it right away. I saw reviews from June that said they had high bacteria levels some days and didn't allow swimming. There's a # you can call on the website to see if it's clean that morning. A must see!!!

Just a short hike down. Limited place to sit in the shade, and even though access is limited it's getting pretty full, but yet, it has a very nice vibe. And it's just so beautiful. But yes, remember to get your tickets ahead.

My kids are loving it. We all loving it. We will come back for a picnic and hiking day as soon as we can.

Great hike to a beautiful place. Get reservations, they won't make exceptions and call first to make sure the bacterial levels are safe for swimming. They say everything you need to know and can save you lots of trouble.

We went to Hamilton Pool simply to admire it. Fortunately, our reservations fell on a gorgeous day which made for camera ready views and quite a happy crowd of swimmers. The path down to the pool is steep and uneven so make sure you're prepared with good shoes and a walking stick if you have any mobility issues. There are a lot of trees so shade is plentiful along the way. Parking is quite limited and sadly some visitors with 'special' vehicles chose to take up two spots. Not cool people! Anyway - it's definitely a must-see and if you have time, bring a towel and enjoy it for a spell.

Clear cool water, come in the morning in the summer so you can run around and not get baked. We hiked the other trail to the river and enjoyed that as well. Make sure you have reservations and go to the bathroom at the trailhead to maximize your time/comfort!

We recently had a day trip to Hamilton Pool from Dallas. As it was April (Spring Time) we were welcomed with lush green scenery and wild flowers. Everything was so lively and green around us that we thought we have come to an enchanted tropical forest. The trek to the pool was beautiful but an easy one (please wear trekking shoes or sneakers, the path can be a bit slippery at times). A lazy river followed us towards the pool. The pool itself was magnificent with emerald green water and a small waterfall. The grotto surrounding the pool was also amazing. The place reminded me of a beach cave in Krabi, Thailand.

Sorry y'all. I know everyone wants to come here when there's swimming allowed, but this is such a peaceful and beautiful spot that all the crowds and chaos that goes on when swimming is allowed spoils it. It's most beautiful on those days when there's no swimming and the crowds stay away.

We hiked down to the pool and enjoyed a walk around the cave in the mid afternoon without a bunch of people around. It looks so much different in the winter than in the summer! I was really shocked at the difference in the landscape. It's beautiful in both seasons because of the differences.

Definitely beautiful all year round.

Google Maps will get you there easy enough, as there is very minimal signage until you get close. Make sure you have a reservation to make sure that you will be let in. Reservations can fill up a few weeks out as well. Also, if you have a morning reservation, they want you cleared out by 12:30 so that they can manage the number of visitors to keep this preserve the fantastic natural wonder that it is.

The Hamilton Pool transports you out of Texas--it seems like something you would find in a rainforest or other tropical paradise. It is definitely worth the drive. Don't count on swimming, though, it is often shut down due to bacteria levels in the water.

Be ready to hike--it is a bit arduous, but our entire party was able to make it and our ages ranged from 8 to a spry 73.

Absolutely gorgeous!! WAY worth getting a reservation! Worth driving to for a day trip! Beautiful swimming area, waterfall, natural creek, views and more!

Didn't think we'd find something so interesting anywhere near the road which brought us there. Getting there early on a weekday worked well because there aren't too many parking spaces, and visitation is limited to a certain number of people. The walk to the pool could be challenging, to some, but it is interesting and worth it. Coming out of the trees to first view the pool is a cool experience. You cannot help but stand there and marvel at it. Being able to walk entirely around the pool offers many varied perspectives. It was worth the drive "out of our way", to visit Hamilton Pool.

Really enjoyed this place, quite unique and took lots of pictures. We did not get to swim, but found the beauty memorable.

As I walked up the trail to the pool it took my breath away. Absolutely amazing!!! We couldn't swim due to recent rain causing e-coli but it was still worth the trip. I'm so glad I was able to check it off my bucket list.

Great place to picnic and swim, but the access is difficult. Do not jump off the cliff, especially at the waterfall. Jumpers have died.

This was absolutely the most amazing preserve I have visited.
It is something people of all ages should visit.
The trail was very passable & clear.
There were a few steep areas but there was a rest area on the trail.
Be sure you carry a camera because you will want to capture the beauty.

I was most excited about visiting Hamilton Pool on my trip to Texas and surprisingly many people I talked to hadn't heard of it. Must makes reservations and must make pretty far in advance especially for a Saturday or Sunday. Wish I had known we could arrive anytime between 9am and 12:30 as I was under the inpression we arrived as a group and hiked to the falls together. That was no the case, qhixh was nice as not many people arrived super early so I was able to get some pictures without bunches of people in the background. Also makes sense on having to have reservations as the beac area isnt very big to accommodate alot of people at once. The hike wasnt bad, due to it being early spring the water was pretty cold. But absolutely beautiful.

A visit here barely beats sitting in a closet staring at a blank wall. Seriously, this place is popular only because of skilled marketing. It might have been nice back in the day, but now you can no longer walk behind the "waterfall" and I'm pretty sure swimming has been eliminated, too. There are some hiking trails, but they're nothing special either...just a walk thru the bushes with nothing of interest to look at. It was so bad that I deleted all the photos I took because it would have been too embarrassing to show them to anyone! Texas has some absolutely wonderful natural areas, but this is not one of them. It's not a dump, and nor is it polluted or unkempt. No, it simply is just boring beyond belief. And expensive! Save your money....you can be just as bored by simply staying home. Yes, my review is pretty harsh, but that's how I tend to react when scammed out of my hard-earned money.

what a place! it's really beautiful. visited Nov. 1, the first day of the season when you DO NOT have to have a reservation. went early so not very crowded yet. water was not as cold as expected and swimming was allowed. the trail down is short but could be difficult with any mobility issues due to stairs/uneven ground. trail around the pool and behind the waterfall is fabulous, especially if it's a sunny day. take your picnic, your trunks, and a camera and be ready for a fantastic day. a must see if in the area.

Thankfully we knew enough to get tickets online before we went. We visited on a Friday morning in early October and it was fully booked. There was still plenty of room on the beach and the walking paths were not crowded. It was awesome swimming out to the rocks under the falls, and my photographer husband got plenty of great shots! Definitely one of my favorite places to relax and enjoy.

that was great experience i enjoyed very well with my freinds. services was good in spring season that was wonderful location we can visite there every time that was so nice place .

Overall, a fun day with my boys. There are two things I would like to voice. Their website states that the hike down to the pool is steep. I guess it’s all relative, but it was not steep. My boys were pretty disappointed that they didn’t bring their tubes to play with because we thought it would be too steep to climb down.
In addition, I really like how they only allow a certain number of people in at one time, but I think they could reduce the number of people per session. It was REALLY crowded on the “beach” once everyone arrived. It kind of killed the experience just a little bit.
Other than that, it’s a really neat place to explore, especially with kids.
Other positives, the staff was really nice and I liked how they had a staff member patrolling the pool area to make sure all was good throughout the day.

Get there early when it first opens! We went mid-October when Nature’s colors were still green with hints of gold and red! Saw some fossils too. The trail from the lot is not that steep, but the trail between the Pool to the River is fairly flat. Take some of the short side paths to view the creek along the way. Be careful of the pair of brazen ducks along the river - they spied our one backpack and wouldn’t leave us alone, hoping we would feed them. The pool is a very cool geological formation - read up on it before you go. It was still warm enough to swim if you didn’t mind water temps in the 60’s. Got some great photos!

We got there at about noon on black Friday and they did not let us in because it was full. But we came back in 15 minutes and it was less crowded and they let us in. But took about half an hour to get in to the parking and find a free spot. Very beautiful place with a short and easy hike.

It was okay...not worth the drive. The water was filthy, brown. And there was not any place to put your things.
We stayed maybe an hour. No thanks.

My husband, friends and myself came here during a weekday and it was wonderful!
1) There weren't a lot of people there and that was pretty nice.
2) The trail to get there is pretty rocky, uneven, steep and wet in some places.
3) DO NOT bring a stroller, bicycle, wheelchair or anything with wheels.
4) Book a reservation ahead of time or call to make sure their open and you can go.
5) The bacteria was high the day we went and thus couldn't go swimming, but we plan on going back when swimming is allowed.
6) The cost was $15 per vehicle
7) It was worth it. The pool and waterfall are spectacular and the hike was just long enough to feel like exercise.

It is a short drive outside of Austin cost $15 to get into the park what you will walk for about 20 minutes down a medium great and then through the woods you will see a breathtaking Watering Hole with a slight waterfall and a beautiful Grotto the water is not very cold and there are plenty of rocks to jump off of into the water and you can walk around the whole Grotto and take some great pictures I highly recommend this as of get away from the Austin city lights this place is very tranquil to have lunch or breakfast there is porta potties and bathrooms in the park this admission will also get you into the river access Park a couple miles down

The hike down to the pool can be a bit strenuous, make sure you have some good comfortable shoes, a bottle of water and a walking stick comes in handy. Beautiful scenery! The pool is not very big and was closed for swimming when we visited, its worth the hike regardless.

If visiting during summer you must make reservations. Reservations are per car, and additional fees are required to enter the reserve (minimum $26, $11 reservation ($10+$1), $15 Admission Fee). Parking is limited, and the area may be unpaved.

The staff was great, very helpful and friendly. Do not get to the preserve more than 5-10 minutes prior to your reservation, you will not be granted access, and there is no parking spots for a couple of miles around, so you may end up driving around until is time to get in. Do not get discouraged, even if you get there early and continue driving around the views are scene is wonderful.

Once parked, you will have to hike 1/4 mile thru the reserve, which depending on the weather around the date, might be somewhat difficult to traverse the unpaved trail.

Great spot for kids, family and couples. If you are looking for a place to get great pictures, or just have a wonderful time swimming and enjoying nature, this place wont disappoint. Be warned, swim may be prohibited depending on bacteria levels, so call ahead if you are wondering.

You may bring food and drinks, but no glass containers. If you do, please take a trash bag with you so you can pick up after yourself. NOTE: Bring water.

Shaded areas may be limited, so if you want to pick a shaded area you need to get there as soon as they open for your reservation time.

There is no lifeguard so you swim at your own risk.

Finally, make sure you walk around the area to get the full experience. The trail takes you behind the waterfalls, and around the pool.

If you plan to visit after September, no reservation is required, however keep an eye out for the weather, and call ahead of time to confirm swim time is available.

Enjoy

Doesn't seem like much as you are driving up. The Ranger at the entrance was a little abrupt about coming EXACTLY at 2 when we had a reservation. But once we got down to the water, it was like another world. Hidden gem!

Don't miss it - it's worth the hassle of getting there.

Semi strenuous walk but worth it. Don’t carry much as tight spaces but beautiful example of God’s beauty and gifts.

We came here for my 28th birthday and what a view! The place is absolutely gorgeous and worth the drive. I live in North Austin so it took about 45 minutes to get there on a Thursday morning. Do NOT forget to make the reservations online. They will not let you in. I've heard you can reserve both the AM and PM slots. We only reserved the morning slot. It is $11 to reserve online and $15 for parking.

I would not suggest bringing a lot of items, just a backpack with the essentials (water, sunscreen, towel). There is some hiking involved. I would recommend smaller children be brought in a carrier. We had a Tula for both our 3 year old and our 18 month old. The three year old did very well on the way down but the way back up is a little steep for him --plus he was worn out from all the swimming. We also brought small floaties and pool noodles. Everyone else did as well. They also provide life jackets but we brought our own. If it's busy, there may not be enough. Adults and children all had a blast. There are catfish in the water and they will swim around you on the shallow end. There were also some turtles. The kids were going nuts! It is a nature preserve so be mindful of that. For more experienced swimmers, you can swim across to the waterfalls. I think it's about 25 ft deep but I could be wrong.

All in all, I suggest go early for the most fun. Even on a Thursday in July, by around 10 AM it was a little crowded but not enough to make my (former military with PTSD) husband uncomfortable.

I visited this with my family (wife and two children ages 7 &12). It was a short hike and we were there. Really cool natural spring and waterfall. We weren't allowed to swim due to high bacteria levels (which has been an issue lately). No big deal for us though, as were didn't want to swim anyways really. We had a picnic on the "beach" area there (rocky island that serves as a beach). We sat down, relaxed, and enjoyed the beauty of the natural landscape and the blue sunny Texas sky.
I recommend this to anyone passing through Texas and looking for Natural escape....

I love this place! I am still surprised that it is not very popular in my part of Texas. Online reservation IS A MUST - book early! We were not able to swim because of the rains and bacteria but still a very good place to visit. It is a short hike, but if you want to walk some more there is another trail to the river but nothing much to see there to be honest. I hope they have a souvenir shop though.

The Hamilton pool was beautiful and relaxing. The walk from the car to the pool was more treacherous than I thought. Should definitely not wear flip flops. Tennis shoes would be smart. It was worth it! So picturesque and relaxing. Will definitely visit again

Short, but steep hike. Really pretty pool and location. Recommend going earlier in the day, as I could imagine it would get hot in the afternoon.

Great outdoorsy place to see. Hike down to Hamilton Pool and swim if the water is flowing. Or explore the surroundings around the cave and pool. Or take the hike down to the Perdnales River. Inexpensive place to bring the family or as a couple. Pets allowed which is great.
Only downside is you have to make a reservation well in advance of your visit due to the popularity.

The Hamilton Pool Preserve is like a dream! Beautiful nature and a large waterhole to swim. The water was cold but in fact of the hot weather absolutely perfect! We were the first ones who got into the pool this morning. We went there early in the morning and had this beautiful place just for us. You have to visit this place!! The easy hike from the car park to the pool was beautiful as well.

Omg! beautiful this place is a must! Yes you have to make a reservation i recommend a 6 months advanced. I made mine on 3/3 for labor day weekend 9/2/19. It was $11 total online to reserved, then when you get there take cash its $15 per vehicle. Pretty long hike like 10-15 mins i recommend taking sneakers for the hike then when you get to the pool change to water shoes. Pack light cause the hike is rough not for elderly. we took lawn chairs snacks and a back pack cooler. Over all is it worth it? YES! O take a trash bag cause there is no trash cans there and a Koozie to cover your alcohol cans.

There is currently, at the date of this review, no swimming allowed still .You cannot even access the trail under the grotto. Based on the TWO fees you have to pay to visit this park, it’s not worth it. There is a fee per car and a fee per person. Oh and also a processing fee because you have to reserve online. If the parks want more people to visit and generate income, maybe they should be working on bringing back the reasons people DO visit. Double fees is just not the move when there are other parks and attractions nearby that offer more for less of a fee.

We were able to swim at the pool, I understand that most of the time people are unable to swim due to high bacteria levels. It’s a very pretty sight to see. Be sure to wear shoes that you can hike down to the water to, and possibly wear in the pool. The beach area is pretty small for the amount of people they let in, so it gets crowded. If you’ve never been, it’s worth seeing.

Beautiful area. Waterfall, pool water was cool/cold, but once you were in it, it was ok. Beach area and water are rocky, wear water shoes or old sneakers. Was .25 mike hike down a rocky steep trail. Definitely not for the handicap. It was a bit difficult for me and my husband, but we made it slowly with our adult daughters help.

First thing you've got to do is make a reservation, we had to book months in advance to get a Saturday at the pool, none the less it was worth it, and it was nice to be somewhere on a Saturday and it not be packed to the max with people. The water was fresh though the waterfall was pretty light probably due to not much rain recently. It was beautiful, just wish the reservation lasted a little longer. The hike is a little rough if your older or aren't in the best shape like me lol so I wouldn't carry too much down to the pool just essentials.

Finally had an opportunity to visit Hamilton Pool Preserve. I was meeting some friends at Commons Ford Park so I made reservations. That has GOT to be the dumbest process. Pay on-line and then pay ONLY cash in person for each person when you arrive. They have been plagued by people reserving all the spots & reselling them. Not sure this new process is helping much. Just collect all money ahead of time and only let the folks in who register. It's how practically everything else in the world works. This place is insanely popular, so it would work and reduce the # of resold tickets. Anyway, that frustration aside, it was a pleasant visit. The place is spectacular even in the dry season when I went. You hike about .25 mile down a very slick path. It's all exposed limestone that has been worn down so be very careful. This is not close to an ADA flat road, so you've been warned. At the bottom, you can go left .75 miles to the river or right a couple hundred yards to the pool. You can no longer walk behind the falls because the ceiling is now unstable but you can still enjoy the scenery. I think you can swim, but it was a no go for me in January! Definitely a place you should attempt to visit, just be prepared for a very Byzantine process and keep trying.

I've seen this listed for years as one of the most beautiful places to see in TX. It definitely didn't disappoint. Reservations must be made in advance.

Beautiful scenery abounds here. Great trails for hiking and a nice pool to cool off on hot summer days. (Please note there are no lifeguards.) Bring a picnic basket and a camera. Reservations are required between May-September to prevent overcrowding so be sure to call ahead.

In all we were very happy with our visit today. Starting off, we had no reservation of any sort as we read their info online and knew there'd be no swimming today but decided to chance it and had a back up plan ready. Expected a fairly long wait to get in - it IS a natural setting and we understand the need to limit human exposure when trying to preserve nature. We were told it'd be about a 45 minute wait - we were parked and loading backpacks for the trail in that time. Yes the staff was a little 'short' but anyone who has worked with the public should understand that repeating yourself 700 times a day can get tedious. My 10 yr old son, 13 yr old daughter & 60 year old mother-in-law made it down to the pool with no problems. And it is amazing. Anyone who doesn't appreciate Gods handi work at Hamilton Pool is blind. This place even impressed my 13 yr old to the point she wants to brings friends back this summer!! The only letdown (I refuse to say "disappointment') was 'the other trail'. On the trail to the river (not the Pool) about half way up, we got some of our best pictures. The rest of the trail was fun for my 10 yr old and I but my daughter got bored and tires and none of us were really impressed with the final view. (Hard to follow up that amazing pool!)
So would we come back? According to the mother in law and both kids - were coming back to Hamilton Pool ASAP!!

Plan ahead and go early. Reservations needed at certain times of the year. Fee is in cash or local check only.

So worth the visit! Is a bit of a hike in with stairs and some climbing. They only let a few people in at a time. $15 entrance. There was no swimming at this time due to high bacteria. It is so unique and such a spectacular sight. You could spend about 2 hours here without swimming. When we left there was a line up of cars waiting to get in. They turn away people if the first gate is closed. In the summer, they take reservations to guarantee entrance.

Wife and I went first weekend in October. Water was still warm enough! In October, reservations aren't required and you can stay as long as you want. No time slots.
We got there about 10 o'clock a.m., an hour after opening. Parking lot was full already so you have to wait in line in your car until a car leaves allowing you to park. We had 15 or so cars in front of us. The park staff was very helpful and knowledgeable in letting us know what's going on. They are preserving the beauty of the place and overcrowding would ruin it immediately.
The wait ended up being about an hour and 10 minutes until we could get a parking spot. We would have rather waited in the nice cool air of our car than stand on foot in line in the sun so we were happy to only have to wait about an hour. We turned on the radio.
First thing we noticed after exiting vehicle was copious amounts of bathrooms. That's a plus. We had a short hike down to the pool. Very pretty on the way down. More bathrooms. A surplus of life jackets hanging up for you to choose from for the kids or yourself to float on.
At the end of the trail is the beach. Small, but compared to the size of the pool It was fitting. It didn't feel crowded compared to the amount of cars in parking lot. It was also quite sunny and warm on the beach area. Large pebbles more so than sand.
You can then proceed to get in water or walk around the entire pool. The rest of the area is under the shade of the cliff. Nice place to cool off outside of the water.
There is a small water fall opposite side of the beach that falls to some slick rocks below. You can enjoy the water splashing on you or it's great for photos.
Saw plenty of fish, and a large turtle or two in the water. The pool was everything and more that I hoped for! Well worth a weekend drive. We saw a few other sights in the area with the other time available.

This is a highlight of the area—a beautiful pool at the edge of a shallow cave with a waterfall pouring over the edge. However, be prepared to walk down an uneven rocky path to get there. At the moment, a bridge across the water is out which means that to gain the far side of the pool, you must walk an additional circular path at the cave mouth. There are steep metal steps at one point and a very narrow passage at another, but when you get to the “beach,” you know the trek was worth it. We went in March, and there were warning signs about no swimming or wading as the bacteria level in the water was high. That gives you a kind of yucky feeling, since you WILL get sprayed by the waterfall as you make your way through the cave. If possible, try to visit on a weekday. On weekends, you will probably have to wait for a parking space. And even on weekdays, there are plenty of people lumbering up and down the rocky path to the pool. Okay, adults may lumber. I saw kids running down the path at full tilt. If you have any mobility problems, bring a cane or walking stick.

The Hamilton Pool Preserve is a park with beautiful nature and a large waterhole which absolutely invites to take a swim in the cool water! It's located in the middle of beautiful nature, so even the drive trough the hillcountry to the park is a delight. As soon as the car is parked, the way to the pool itself follows. It's a walk of about 10-15 minutes and highly enjoyable. The hike is very easy. You should be able to walk without any problems but the hike is really easy. Just stay on the paths. And make sure to be there very early, before the park opens. A lot of people love to see this attraction.

Hamilton Pool itself was very nice. The entry to the park is us$15 which would be fine if the park was actually open.
At the time I visited they were advising that one could not swim nor make any contact with the water as the bacteria count was too high. This I don't have an issue with, but reduce the price accordingly. On walking down the trails, I discovered only the trail to the pool was open, the river walk and all other trails were closed. Again, no issue, but reduce the price accordingly. The attentant at the entrance was also far from courteous and purely just there to collect the money.

On a brighter note, the waterfall was running and the pool itself a nice place to visit. The walks that were open were pleasant and not in any way challenging.

Call ahead to get the instructions, reservation info and cost. +1 512-264-2740. Very crowded in the summer. Must be able to hike a bit, but all ages can enjoy. Sometimes can't swim because of bacteria levels in the water. Even with many guests there as well, it was a lovely spot.

When we were driving to the Hamilton Pool we saw a few signs saying that you need to book tickets online. Luckily we chose to go on a weekday because then you do not need to book a ticket, or they were slow that day but it is worth checking out before driving out there.
The walk to the pool, the pool itself and the walk behind was really nice. We did not realise that we could swim in it but bring your trunks and towels just in case you decide to.

Definitely not worth a drive to see at this moment in time. A costly experience to see a quite underwhelming large puddle !!! Walk to the river wasn’t particularly worthwhile in terms of vista’s either. I’d give it a miss !

Loved this place! Beautiful photo op! We went in March. The water had a high bacteria level due to recent flooding I believe, so we were not able to get in it, but it was an awesome sight to behold and well worth the short hike.

Definitely a place to visit. Need a reservation that you get online($11) then
you have to pay $15 at the park to get in.
The trail to get to the pool is .25 mile. It is no handicap or disabled access. It is very rocky and when it has rained (in our case) very slippery. There is no food vendors so make sure to bring snacks and drinks! It is a beautiful area to have a picnic. They do have another trail .6 miles that takes you to the Perdenales River.

We hit up Hamilton Pool the day we landed as we were meeting some friends there. You have to make reservations for a time slot ahead of time about three months in advance. Even with the reservation system, the parking lot was packed and we were worried about finding a spot. Once we headed down to the Pool, which is an easy hike, it sounded like a party was going on down there. We weren't sure where our friends were (as they arrived before us) and we had a hard time finding them since the beach area and water were both quite full. We even had difficulty finding a place to put our stuff down on the beach. It was hot when we got there (around 102) so we got into the water as quickly as we could. The water was a bit cloudy which was probably due to all the people in it. I've been told that it looks a lot clearer when there are less people/in different seasons. Eventually we located our friends and moved over the rock area on the opposite side which was much less packed but a bit more difficult to get into the water. We had a lot of fun there even though it was a busy day. Definitely wished we had brought a floatie as we saw a lot of people using them.

My kids and I had a BLAST! We loved hiking around and exploring! Plus, what a beautiful sight to see!!

I have been waiting to check this off of my bucket list for FOREVER. and I finally got to go today and it was soooo worth it! Absolutely stunning. We went as soon as it opened on a Friday morning and there was no wait, but I have heard they turn people away. In fact, as we were leaving around 11 am, we saw them turning people away because the park was full!

Anyways, the park was sooo worth the drive from Dallas! It was absolutely stunning, even without being able to swim until May. It was just sooooo beautiful!! Beautiful blue/green water and waterfall. The river hike was lovely too! Loved the pool itself! Just out of this world!! Must see!

We went during the winter and there were only a handful of other people there. It made it really enjoyable as we did not have to deal with a ton of people on the trail and made for some cool pictures since no one was swimming.

We drove an hour and half to get here from San Antonio Texas and I would it again to show off this TEXAS GEM. I was amazed of this awesome Creek and waterfall and pool. We couldn't go in the water due to high bacteria because of recent rains. But the hike and the views where great. You should call ahead of time just in case it's to full of people or If you want to jump in the beautiful waters. Highly recommended. Love TEXAS!!

You have to go there is you're in Austin... not so far, and even if you can't swim, you can spend nice time walking around this natural pool... do not forget to book the visit on the park website

This is a must see near Austin. Go during the week when there are less people and you will get great pictures. It is stunningly beautiful. We could not swim the day we went because of high bacteria levels - not sure what that is all about. But wow, just seeing it was worth the trip. $15 to get your car in. Bring your camera.

I was a bit overwhelmed with all the information online about reservations, waiting, etc prior to my visit but my experience was just the opposite. I arrived at 9:15 am and was the only person there during the entire time of my visit. Yes, I had the entire place to myself! Now I must also include that it had rained the day before making puddles on the trails and it was also only 55 degrees outside that may have kept other visitors away. With that said, though, the hike to the pool takes a lot of effort so the colder weather didn't feel cold at all. I was even sweating. Personally, I wouldn't want to do the climb in weather much warmer. The pool was marvelous! Very much worth the $15 park entry fee, which is a pass that allows entry to many other local parks for the day too. The rangers were very informative. They answered a few questions I had about local birds in the park. Best advice - take one of the walking sticks at the start of the trail! The path is very rugged and it would had been very helpful if I had done so. It was a very nice visit and everything photographed beautifully. Such an amazing place.

This place is worth the drive! it's gorgeous and is an easy hike!
I would suggest you arrive early!!

As others have said, it starts with a well maintained but rocky walk downhill that requires attention (and loss of mobile service). This just builds the momentum for the destination ahead. As you walk you hear international voices all around and the rush of the stream below. If you haven't seen it before, your jaw will drop at first and then you will be beckoned to walk behind the water fall. Allow at least an hour (round trip)and take your time and enjoy it. Please note: This attraction does not allow pets in the park (at all). Fall seemed the best time to avoid the crowds.

Went on spring break and it was very crowded. But it was very beautiful. I thought the waterfall was/stream coming off would be bigger than what it was. But it was a fun hike, and beautiful water. And it was very crowded on the small beach area, so avoid spring break

I love Hamilton pool. It is a great way to spend a couple of hours. There is a gorgeous hike near the pool as well.

The park was shut down due to high bacteria counts. Guess we were unluckily. Also due to overcrowding need to make a reservation or something like that. Don't forget or you will be put of luck.

The pool and water are amazing, the path can be steep in some places and it isn't bad going down but going back up is a pretty good workout. The staff entering the park were short and rude, the parking is tight, but luckily you have to make reservations so they only allow so many people in at a time, overall I recommend it and plan to go back.

Went here on a Sunday in October.
Parking was a little tight but ended up getting a spot.
The walk down to the pool and waterfall isn't that hard. Spend time down there walking abut the pool area. Lots of great picture opportunities.
Then did a little of the walk along the river in the opposite direction.

Main item is that it is probably really crowded during certain days/months, so definitely need to plan ahead as not alot of parking there.

Overall a good experience that didn't cost that much and allows for 1 to 2 hours worth of good activity.

Must have reservation for 4 hours use morning or afternoon! We were visiting from Australia and drove all the way there about 100+ miles out of our way only to be turned away! Wouldn't even let us just have a look! Very poor service!!!!

Wow, a truly awesome setting and a natural wonder swimming hole.
A booking in advance is suggested however we got in on a standby list. Not a free access swim, the cost can vary. You pay when booking, and again to get through the main gate.
The walk down into the gorge needs a pair of sandals at minimum as there are trip hazards and steep rocky steps.
There’s not much in the way of facilities so be prepared to lug all you need down and the trash etc back out again.
It is very, very deep. So don’t go past your depth if you can’t swim and please look out for your children.

This was one of the highlights of our trip to Austin. Such a beautiful place. And we loved the strict rules the park has to make sure it's preserved. Sure, it takes a bit more effort to get tickets and such, but it's definitely worth it.

We hope to visit again some time, absolutely loved it.

Definitely bring water shoes if you plan to go in the water. It's very rocky and painful to step on. Hamilton Pool is such a beautiful place! Hold hands of little ones and be careful on slippery rocks around waterfall.

Given the popularity it is really Not overcrowded. The park does a great job of keeping things regulated. Beautiful scenery. What a nice spot.

A short .25 mile hike takes you to the pool. Little steep at places. Once u reach the pool u are awed by the grotto. Looks very picturesque. The water was very cold and needed sometime getting used to. There are lifejackets available to use and return upon leaving.

Reservations required, 365 days a year. It truly is beautiful, but the intense popularity may not be what you’re looking for.

Reserve early- park limits daily attendance to only about 250 but it keeps the experience more intimate ( as opposed to a big water park)

We love this beautiful place! Water is always so cool and inviting. Have been taking my grands there for the last several years when they visit. It is a rather small area of beach and quite a trail to traverse down to the pool but the beauty of the walk down, overhang of the rocks and vegetation along with the serenity of the water area make this journey magical.
Get there early as they have limited number of space available.

Absolutely stunning place. We were so glad that you needed a reservation for this or it would have been overcrowded. While it is not a place for solitude by any means (think more like a freshwater beach), it is still a great place to relax and take in the scenery. We could easily swim without hitting anyone which was nice. Also, there is no music allowed so you could enjoy some “peace and quiet”. The reserve has turtles and big fish in it as well so it was quite a surprise. One tip is to arrive at your exact reservation time. We arrived early and they told us we were not allowed to come in yet. You will also need exact change, in cash only, in order to park. We will certainly be back

It was a rainy day outside on the day that my buddy and me went to the Hamilton Pool Preserve. We went there because we heard that you can get some great photos and the views of the water and the waterfall. Being able to visit in person was breathtaking and thankful the rain let up in the afternoon to truly enjoy this amazing place.

A reasonable drive from Austin, 10-15 minute easy hike to that place and... behold! A beautiful nature creation you don't see every day.

1st, you need to make reservations way in advance. We made ours in April for the end of July and there still wasn't any Saturday or Sunday reservations. In addition to the reservation fee, you have to pay for parking when you get there. There is about a half mile walk to the pool. I don't recommend bringing a rolling cooler or anything with wheels. There are steps you have to go down to get there. We brought a bag cooler we could carry and an all weather blanket to sit on. I recommend bringing pool noodles or small intertube to float as the pool can get very deep. They also have free life jackets to use which was great because although both of my kids are strong swimmers, I liked the security of them having them on so I didn't have to watch them every second. They are 12. There is a small beach to put your stuff. It wasn't overly crowded and everyone was very nice. The water was cold, but you get used to it. There is a waterfall and a large rock to jump from. It is neat to see the fish swimming around you. We stayed for 2.5 hours and it was perfect. We had an afternoon reservation (2-6p). I recommend it, however, it is not a resort pool and I think if you keep that in mind, you will have a good time. If you think you are getting luxury, that is not happening.

You have to make a reservation, its really important to get to their website and make the reservation, they took my license at the gate and searched for the reservation. from the parking lot, its not far to reach the pool but be prepared to climb some steps. I have to be honest the pool itself was a disappointment, there's no waterfall this year due to the drought, the ranger said the waterfall had disappeared and we don't know if it will come back and they won't allow you to walk behind the pool to take pictures due to falling rocks, so 5-10 minutes at this point is enough.

Amazing natural underground pool, waterfall, beautiful trees around. Very peaceful place, not very crowded, because they let you in by reservation only, which is very nice, this gorgeous place is so worth preserving. We couldn't get in the water, because rain brought too much bacteria, and it was very hot that day. Hopefully next time, we will be in luck to swim in the pool. Bring a lot of water and wear comfortable shoes, there are a lot of rocks, so my flip-flops weren't the best choice of footwear. We also hiked along the river, water was super clear and calm, for a moment there I felt like I was hiking in the middle of the jungle - it's so secluded and different from other parts of Texas. Overall, amazing!!!

We walk back to the pool is interesting and the pool itself was beautiful.
we also walked back to the river, about 1/2 hour walk there and back. Really pretty walking along the stream leading to the river.
Thought though that for the 'winter' since you aren't going into the water and using their life jackets, $15 was a bit steep.

We drove from San Antonio only to find out you needed reservations. We only had a day to spend in the San Antonio area (traveling in RV from NH) before we headed off to Arkansas. Guess we will never get to see this place

It was a blast!! So beautiful, but a little crowded. Get there at the beginning of your time slot for your pick of beach area. It's very small. Walk around the entire pool! It has amazing views!!

Love to take guests here because it never fails to impress. If we are all in an ambitious mood, we extend the fun down to the Pedernales. The walk along the creek to the river is relaxing and beautiful to boot. Go at any time of the year. It is always different so no repeat visitor is ever disappointed. IF AT ALL POSSIBLE, stay away on the weekends. If that is the only time you can go, go early and ignore the crowds.

We were told to get up early to get in. So glad we did. We were there 30 minutes before the gates opened and there was already a line of cars. But, we got in! It was so worth getting up early for. This place is incredibly beautiful. Like nothing we've ever seen, at least not here in Texas. Even with the crowd, it felt like an oasis... although being there when it's less crowded would make for an even better time. When we went they still weren't allowing any swimming (it was too cold for that anyway as far as we were concerned). But we were told that once the bacteria levels went down AND they got in their shipment of life-jackets, they would reopen for swimming. (Apparently there have been a few drownings in the past few years... people who don't know how to swim, try to anyway and there are no lifeguards on duty. It's a natural pool people- that is 20-30 feet deep in most places and drops off quickly. If you can't swim, don't!

In some regards it was prettier without the swimming the day we visited because the water was a beautiful teal green/blue... when swimming is allowed it kicks up silt and clouds up the water to more of a brown color (so we were told). We also enjoyed taking the other trail the opposite direction that leads the the main river. It was much more secluded and not a hard hike.

If / when we return, next time we'll try to go when we know it's not a heavy traveling season (we were there on spring break - and we hear summer isn't any better) AND we'll plan to take a blanket and picnic and spend more time just admiring the calm of the pool area.

2nd time visiting this amazing place. First time with my wife and her side of the family. The drive from Houston is always enjoyable and so was the preserve itself! I’m always amazed at how this is one of few places that actually looks exactly as beautiful as it does in its pictures. First visit we had to wake up super early and make sure we got a spot at the front of the line. It was March, water was freezing. But it was still fun! This second time I reserved our day for late July in early April and definitely preferred it this way! No waiting in lines, just show up at our scheduled time and go right in! This time it was sunny, hot, and the water was perfect! Only negative would be that the employees there did NOT enforce the rules and allowed a whole group of college aged adults to drink alcohol and spill their drinks in the water!! 🤬 there were several other families there (not enough to feel crowded) and I’m certain they too did not appreciate having beer and garbage floating around and ruining the pool.

Aside from that, this place will always be special and I can’t wait to visit again soon.

We stopped at the pool on our way to Waco. The trail to the pool was steep and rocky but it was worth the time to stop and see. The trail runs behind the overhang making for very scenic photos.

MAKE A RESERVATION! Some people think it's a pain in the butt, but I personally enjoyed that they control the crowd. It made for a peaceful and relaxing day at the reserve. The pictures do not do it justice. You have to see it for yourself. Small hike to get down to the reserve, they offer life jackets that I used upside down to "sit in" as a float. It was the perfect day.

I grew up hearing about kids sneaking into this mans ranch to jump into something called Hamilton Pool. Fast forward 30+ years and I live about 10 miles down the street from what is now a Preserve. I took my family for the first time at the end of last season and it was beautiful. The reservation system worked flawlessly and when we arrived we went strait in - much better than the prior attempts to visit before the system and the pool was full. This is a small but beautiful oasis. Walk the cavern, swim in the water and stand under the water fall. It is all beautiful.

Read about this in Texas Travel Guide and had to see for myself. What you don't know about the places is how hard is it going to be to get there. But this is about 1/4 mile walk down some rocky terrain. I'm no regular hiker, and I carry a lot of photography equipment, but I'm 65 years old now and don't go too far. This place is well worth the effort. It is like looking into an underground cave on one side, water dripping off the cliffside. It was closed to swimming the day we went due to high bacteria count in the water, so you might want to check that out first if you mean to swim. First you get to river in about 5 minutes from the parking lot. Perdenales river flows thru old cypress trees. Then you get to the pool and it is awesome. Fortunately for me it was a cooler winter day and a lot of people weren't there. I'll let my photos do the rest of the talking.

If you can get a reservation (they fill up fast), this is a beautiful hike and swimming area. We were there the first day they were open for swimming after it had been closed for a while due to the risk of falling rocks so we were not prepared. We hiked with a picnic and just looked at the pool, grotto and waterfall.

It was nice to see and there were interesting things about Hamilton Pool. Hike, compared to Jacob's Well, had more terrain. Water shoes highly recommended. Waterfalls and its natural beauty was awesome. Water was not as cold, refreshing, or clear as Jacob's Well (the first stop on our road trip), so it was not as inviting for me to jump into. However, the kids ages 7-9 LOVED it!! They swam across it, stood under waterfalls and jumped off rocks. The preserve itself was gorgeous! My boys loved seeing catfish in the water and other animals.

Highly recommend making a reservation online, as number of people are limited at a time. Also check if swimming is allowed on the day you go.

I was happy to see this place at least once, but, the water (for me) was warm, murky, and smelled. After my friend told me where the water comes from, I'm not sure I'd go back to swim.

The walk to the waterfall/pool isn't too far but it's down lots of steps and an uneven rocky path. It's very shaded, beautiful scenery. The waterfall itself is small. Photos of the cave do it no justice. The pool is lovely and clear. It was very cold water, but that didn't stop my son and I from jumping right in. They have life jackets available, due to the pool being 25ft deep in the middle. We got there at 9 as soon as it opened, not long after there was a crowd. To me, they let too many people in. You can hardly get a good picture without anyone in it. We also did the hike to the river, just under a mile, which is definitely worth it! It's beautiful, perfect for paddling in. There was nobody else at the river when we were there. It's $11 to make a reservation online which covers one car with up to 8 people, and then you also have to pay $15 cash for parking. They only let you in with a reservation.

We were visiting from out of town, and a friend had recommended this to me. I'm very glad that she did. The walk was about 1/4 mile over some rocky terrain, but not bad at all (and I'm 68). It's not like anything I've every seen before. Beautiful cave, pool, and waterfall. Definitely worth the walk.

A definite MUST SEE!! Nice little spot to relax, so soothing. Be sure to wear your hiking shoes! We went when it had rained so it was muddy. But very beautiful! We'll definitely come back in the summer hopefully be able to swim next time. Theres a stream that you can hear as you get close to the pool. Pretty neat place!

Bring cash! Made the mistake of assuming I could use credit/debit card! Had to drive back toward Bee Cave almost ten miles to find an ATM.

That being said once there we found it to be as stunning as the photos you’ll find online! We were there on a Monday afternoon in October so it wasn’t too crowded. There is a strict limit in the number of people they allow into the park so plan accordingly.

The hike down into the pool is about a quarter of a mile. I suggest not wearing flip flops or shoes with heels (yes, we saw that) as the path is stones and tree roots on a fairly steep path.

CAUTION. COVID19 RULES. Although the spot is extremely beautiful, you have to reserve ($11). Then when you get there, they charge you per person ($8 per adult) and tell you that due to Covid19, you cannot swim.

So you are being charged to look at a pool.

We weren't allowed to swim because of the bacteria in the water, which was a bummer. However, the water in the creek was clear until you made it down to the main river. We did see a water mocassin in the creek so be careful. We would definitely go back especially if we got to swim in the pool area. The hiking was wonderful. My six year old got a little cranky toward the end but it wasn't bad at all. The weather was great and the scenery was breath taking.

Wow! So beautiful! Hike down was a bit rough, since I have a bad back, but I was able to make it and I was so glad I did. We later found out you can ask for a transport cart to take you up/down. Just ask where you stop to pay for entrance. It was SO helpful. No chairs or benches once you reach the pool area so bring them if you'd like to not sit on the gravel. Portable potties are available not far from the pool. Amazing views and a walking path under the cliffs that surround the pool area. There is a beautiful water fall too. Water was pretty cold though. I highly recommend you visit!

an amazing and beautiful experience and exercise. So beautiful and natural! Amazing experience, I will never forget it! Clean water and park. You can climb around the fall so you can be under it.

We went to Hamilton Pool in the spring without a reservation and got in just fine. In the summer months you need to make a reservation to enter. The day we went they didn't allow swimming but it didn't matter. It was breathtakingly beautiful. We enjoyed this even without being able to get in the water.

We've driven to this place twice from Dallas with friends and family, and have recommended it to over a dozen people.
This place offers a spectacular view of water dripping from the top. The semi-circular waterfall (sort of) was formed when a portion of earth caved in many many centuries ago..
People can swim here when allowed. This week when we visited, they even had a small shop right at the pool for life jackets..
I've heard that the place can get pretty crowded during summers & holidays, so much so that they stop entry as well..
There's a $15 charge/ car for entry - Totally no worth it since the area is pretty small & the pool is the only attraction.
It's a short walk - about 15 min, 0.25mile hike to the pool - the path is unpaved.

Gorgeous...must have reservations. The hike down to the pool is awesome. Nature at its best. Could not swim or get in the water due to the high levels of Ecoli Bacteria, but did not ruin the trip. Simply gorgeous & relaxing listening to the waterfalls!

We enjoyed the hike but were unable to get into the pool due to the earlier rains. when it rains they close water contact due to bacteria and on hot days they have a limit on the amount of people the let into the park

If you like beautiful places that look like they belong in a fantasy novel then this is the place for you. It was not busy when we went but it was also slightly rainy. If the bacteria level is too high they do not let anyone swim in the pool. The entry fee is 15.00 and you should call ahead for reservations. #nowastedweekend

We had a great time! Do make reservations well in advance. We were trying to go on a week day in May, and we had to delay our trip a day because they were sold out! We walked around the entire pool, which we recommend. It's wonderful to see it from all 360 degrees. Some people brought folding chairs and blankets to sit on the beach. The water is a crisp 68 degrees F. It is beautiful. The rangers shared great historical information about Hamilton Pool. We ventured to a park just down the street that rangers told us about and we climbed down a pretty easy hike to the Pedernales. Also totally worth it.

My daughter and I thoroughly enjoyed this unbelievably beautiful part of our state of Texas. We made the required reservations a few weeks in advance and luckily had glorious weather! Come with $15 cash only for the park entry. The hike down is a bit rugged but not impossible for young or old. There are large rocks to negotiate but they are nature’s steps. I have had hip replacement surgery and it was no problem for me. It’s just important to watch your step. The whole hiking and walking experience was fun. We didn’t swim because of the bacteria in the water but it didn’t disappoint us. You can take towels and snacks and sit and enjoy the scenery. I can’t wait to go again! Breathtakingly beautiful! If you like hiking and nature, you will love Hamilton Pool. I highly recommend this for everyone.

My husband and I stopped here after a morning of driving through Texas Hill Country. I was nervous because everyone talks about how busy the trail and park are but at 3pm on a weekday in the winter it was almost deserted. The hike itself is easy and the views are spectacular. The color of the water in the river and the lagoon are breathtaking. We walked the river trail as well which is another lovely little hike. This is just a peaceful, beautiful park and I wish we lived in the area so we could visit more often.

As a geologist, I've been wanting to visit this place for years! I finally did and it did not disappoint. It is absolutely gorgeous and unique. You have to pay to make reservations to visit, and then you have to pay/vehicle once you get there. CASH ONLY. Total it was less than $35 and it was worth every dollar. The water is cold and stays relatively cold while you're in it due to the waterfall. The beach area is VERY rocky so I recommend wearing water shoes. It is also a bit of a hike down to the pool. I took some rafts with me which worked out well. The water is not shallow enough to stand everywhere. If you are considering coming here make reservations far in advance!

There is good and there is bad. I think most people have touched upon each in the reviews previously. You need a reservation (costs 15 or so) and then an entrance fee (costs 10 I think). If there was rain recently (or other reasons it seems) you will not be allowed in the water. It is still beautiful, but given all the negatives the cons are beginning to outweigh the pros. If you find yourself out there with either no reservation or no ability to get into the water you can literally head 3 minutes away to another park that is $10 and more easy going. There was plenty of hiking at the other site as well as water access on a day that Hamilton Pool was closed. I might still say to try Hamilton first (even with the higher cost), but if they are full or closed or not letting people into the water there is another option right down the river.

When I went there were only 4 people there. The water was clear, the waterfall was pretty, the overhang to get behind the falls was worthwhile. Even the hike to get there was nice.

The hike to it is a little strenuous but so worth it. When you see it you will not believe this place is in Texas! You have to make a reservation & water shoes are a must as the bottom is rocky. We enjoyed 4 hours there & had the best time! The water is so refreshing & there are shady places to sit if you do not want to be in the sun.

Extremely popular attraction. Advance reservations required (pretty much booked every weekend going well into October). Make sure to wear proper shoes because you have to hike down and back up. Some individuals had on flip flops and had extreme difficulty maneuvering through the rocks. The hike is only 0.25 miles down to the pool.

Don’t be upset, but you may not be able to swim due to high levels of bacteria in the water but luckily we were able to.

I feel like the area is too small to accommodate the amount of people there but many people left early and didn’t stay the duration of their reservation.

The parking isn’t the greatest and they won’t allow you to come in early (if your reservation is @ 2 pm; they may allow you to come in @ 1:50 pm and that’s pushing it)– you have to park at the nearest park and you have to pay to get into that park as well. You have to pay to park as well.

The water was filthy and brown – not blue at all like the pictures.

You hike down a relatively short steep rocky trail and then follow a crystal clear stream until you arrive at the pool, In late January you couldn't swim but we hiked all the way around past dripping moss and waterfalls. A little piece of Norway in Texas!

Definitely go here, it is a short walk down to the pool. Only bummer was the $15 fee when I was there for only an hour or so.

Teens will reach rock star status with an instagram post from this place. My niece took her giant inflatable swan (and the pump) and made quite a splash. Fish, turtles, beach, perimeter path, and a waterfall shower. Reservations are required, but it is worth the effort and planning. Take snacks and water for sure, towels and chairs if u don't mind carrying them the mile-ish hike to the water. Water hikers (Chacos, Keens) highly recommended for the slick and rocky terrain.

We lucked into a reservation and scrambled to plan our trip. It is a 2 hour drive for us so we had high expectations. The place is lovely and we, fortunately, arrived early. It became too crowded for us very quickly. What a great experience! We will be back.

This was beautiful and worthwhile. Off the beaten path. Wear good shoes and your swim suit trust me. RESERVATIONS ARE REQUIRED AND BRING CASH FOR PARKING. You must make the reservations prior. I think its like $20 total and $15 to park. Great family spot! Oh last but certainly not least BRING SWIM SHOES. The rocks are brutal. NO SAND. Good luck!

This was our second visit and both trips were great, but I prefer summer opposed to fall to swim here., there’s just something about being super hot and being able to cool off in that cold, clear water!! Going in the fall was a much more pleasant hike though.

We visited the first weekend in December and had a really nice time. There was no wait to enter. The pool is reported as the prettiest place in Texas and they may be right. We took lots of photos and enjoyed both the pool and the hike to the Pedernales River. The only negatives were from the people that attended that weren't being respectful of others, namely the latin guy and his girlfriend in the red shirt that were blaring some terribly distorted 'music' on the beach at Hamilton pool while everyone else was trying to enjoy the peace and natural beauty of the place. It wasn't that he wasn't aware as plenty of people made comments sneered or jeered, he just genuinely like getting negative attention. The park attendants didn't bother to intervene. The same blue tooth speaker Richard head then decided to take his party on the road and took the hike to Pedernales river with his music still playing. They there is the 'lady' who left her toddlers dirty diaper on the side of the same hiking trail and there is the woman with the tiny dog on the leash that consciously avoided the abundance of signs that said no dogs, no dogs on leashes, no dogs left in cars, no dogs whatsoever. She smuggled in her guinea pig sized dog despite the rules. Unfortunately you have to really get off the beaten path to get away from those that conspire to ruin it for everyone else. Hamilton Pool is about the best nature experience without the inconvenience of really getting away (at least in December). I can imagine this place would be an absolute mad house on a hot summer day. There is a limited amount of parking and the slowish December day was fairly full. I imagine with would be quite frustrating in the warm months to show up here and face a crowd. It may be best to call ahead and inquire about the activity level as that has quite an influence on the experience.

Must see. This is one of the best places in Austin Texas. It is magical. You have to go here. So beautiful.

If you like prestine nature this is the place.Primitive trails. great outdoor fun trip. If you like to swim in natures pools this is one to visit. You must be ready to rough-it a little but will enjoy the outing.

If your looking for a day out with a little hike and a naturally beautiful pool .. check it out .. in my opinion not for young children

Spent the morning at Hamilton Pool Reserve. Easy hike, beautiful water to swim. It was very warm outside but the shade of the cliffs made it the perfect temp outside. This was better than expected and cross off my bucket list!

Hamilton Pool Reserve is a gorgeous place once you get to the water... Upon arrival we paid the $16 per carload entry fee. We were told there would be a 1/4 mile trail leading to the pool... It was NOT like any "trail" I had ever seen, more like a washed out, extremely rocky hike... But the end view was awesome! Worth the visit and entry fee, just be warned about the so called "trail"...

We arrived on a Saturday around 9:01. We were about the 3rd car there. It was a beautiful morning around 75*. It seemed like we had the pool to ourself for an hour. I got in the pool only knee deep because it was chilly. We then did the hike on river trail and that was fun! The river at the end was cool. We got to see a turtle. I do feel people should wear proper footwear. A family was coming down for what looked to be bridal photos. They were wearing boots and heels! The little girl fell on the slippery rock😧. Please wear tennis shoes and change at the bottom. These trails are slippery, steep and uneven. I recommend a walking stick for those who have balance issues. Thank you for the hand sanitizer in the port o johns !

Drove over two hours to get there and denied entrance. They said reservations were needed. We had a screaming baby in the back seat that needed changing, they didn't care. They told us to go to another canyon right down the road that was exactly the same, well THAT WAS CLOSED TOO!

Pretty much always full to capacity during swimming season. It’s a beautifully natural location and swimming hole. If you want to swim I’d say plan on getting there early. If you’re taking photos probably go in the cooler seasons. To get to the swimming hole is a pretty good hike on uneven paths. There is a pretty good decent on the trail down so pack as light as possible. Well worth seeing for one of the area hill country treasures.

The pool is breathtaking. One of those spots where you know the photos won’t do justice to the scene. I try anyway, and spend some time walking around the cave and behind the waterfall. Part of the Balcones Canyonlands Preserve, the pool and grotto were formed when the dome of an underground river collapsed due to massive erosion thousands of years ago. No queues or waiting when I arrived (a Friday afternoon in October).

There’s an inviting beach and the pool has been used as a swimming hole; a number of signs prohibit swimming due to high bacteria level. (On questioning the very friendly and helpful park ranger on my way out, it appears that there have been a couple of swimming deaths in recent years, and the swimming ban is less about bacteria and more about preventing any further drownings.)

It is a rocky hike to get here but so worth it. Carried a cooler with some drinks and snacks- a must do. We will be back. Reservations are required in the summer!

I was lucky enough to get a ticket for the morning slot. Arriving at Hamilton Pool first thing in the morning is definitely recommended: I had the pool all to myself for 15 min, which really is a magic experience. The water is pleasantly warm, and floating in the pool, watching the waterdrops fall down from the rocks way up is just amazing and incredibly peceful. When the masses arrive (bringing all kinds of inflatable plastic toys), it‘s time to leave though.
The place is well kempt, clean; the trails were partially closed due to rainstorms, some of them open, but wet and slippery. I saw people wearing flip-flops and having a hard time, so even if it‘s only a super short walk, choose comfy sports shoes to go down to the pool.

Gorgeous! Go in the off season. We ate a picnic lunch at the tables near the parking lot and then hiked down to the pool. Also took the hiking trail to the Perdenales River. Very pretty hike!

No longer worth visiting.

I came here several years ago, and had a great experience walking the circumference of the pool, but since the winter of 2020 you can no longer walk u der in any overhanging spot. The only viewable spot is a small beach that allows you see less than a quarter of the site. Swimming is seems to be closed the vast majority of the time but the county still has rows of life jackets on a rack fading in the sun. Even if open the swimming area is a small roped off section.

Even the trail along the creek to the river is closed with a sign warning of fines if crossed. The walk is just 10 minutes from the parking lot.

A lot of people may want to visit after seen old images on Instagram, Pinterest, etc, but pretty much none of that is accessible or even visible today.

It simply isn’t worth the hassle of a reservation system which requires you to pay even more cash when you show up.

Until Travis County gets active and does something, visiting this site will be a disappointment and just a waste of time.

Definitely worth visiting this magical place. We went on a Monday and thee were only a few other people there. The pool was crystal clear blue water. Lots of small water falls. No swimming allowed. Followed the easy 0.6 mile hike down to the Perdenales river.

The views were so beautiful. A wonderful relaxing spot you won’t find anywhere else! Be sure to take the extra hike down to the river also. You’ll need closed- toed shoes but it’s so worth it!

My 15 year old daughter and I spent an afternoon hiking down to the pool and along the canyon trails and loved it! Although no swimming was allowed due to the risk of falling rocks, it is still very much worth the time to visit and explore!

I went to scout this place for pictures. it is a beautiful place and you will enjoy being in contact with the nature. I recommend arrive to the location early to take great pictures

Hamilton pool is ok to visit once. The actual pool area is very small and gets really crowded in summer. You have to reserve beforehand on their website otherwise you won’t be allowed in,don’t even try going if you have not booked in advance. We had to book on weekdays cause all the weekends were already booked. Also they have time slots 1st half and second half,you can not book for the whole day to be there.Nothing much to do activity wise. The restrict swimming in the pool from time to time so look for that information on their website as well. If you don’t care much about getting in the water,would suggest to go during winter as its less crowded in the winters.

This is a beautiful place and definitely worth visiting at least once. Just make sure that you reserve online and plan ahead. Make sure you have cash for the entrance fee per car because they do not accept cards. Also, be sure to check their website before you leave to make sure the pool is open before you leave. If you call the number, it is updated more frequently. The hike down is a little steep, but not too bad. It’s not long. Only a little over a half mile. We went first thing in the morning when they opened and on a week day so that it wouldn’t be too crowded. I did bring my 3 year old and he had fun hiking and running around.

Never been to a state park where a reservation was required. Still haven’t because they turned us away, after having driven 2 hours.

Reservations were not needed for our weekday morning visit to the preserve in November. We did need to pay $15 to park. The parking lot is quite small so I do not think I would take an RV into it.

Although the walk to the pool is only a quarter of a mile, it is a challenging hike for senior citizens. The downward trail is filled with rocks and large steps that are difficult to navigate.

All in all we enjoyed the hike around the pool and the lovely scenery.

We went mid week at 10:30 am, mid March. And still there was a wait to get to in. Limited parking. Cost $15 per car, for us seniors $5. It's a beautiful hike down the mountainside on a well maintained trail. We had our own hiking sticks and were happy to have them for both the down & up trek. Suggest you bring them if you have them. There are limited wooden poles there, but most were in use. It's only a short hike, but well worth the wait (for us about 1/2 hour). No swimming allowed due to bacteria in the water. In fact, we were warned to have to contact with the water altogether.

Really enjoyed the morning at Hamilton Pool on our first trip to Austin. You have to reservations in advance so keep that in mind. There was a short hike down to the pool with some nice scenery. The water in the pool was a little cool but refreshing. It was cool to swim across the pool and stand under the waterfall. My only regret was we didn't get there sooner to enjoy the full 4 hour allotted time slot for the reservation. It was a highlight of our weekend trip!

Hamilton Pool is very relaxing and great place to visit. We found it to be very relaxing and it seemed like all the visitors were there to enjoy a peaceful atmosphere. It was also nice to see that other visitors respected the sanctity of the location by packing out what they took in so the pool area is unlettered, un-graphitied and not down-trampelled by those going "out of bounds."

The trails are a little steep in a few places, but not long or arduous. Basically manageable if you need to take your time. Also, depending on the time of year and rainfall, they could be a bit slippy. All and all, however, we found other guests to be patient and pleasant allowing people to take their time when they needed a bit extra.

When you want to swim in the pool - stay away. We made a reservation and went there but at the entrance there was a sign with no swimming because of high bacteria level. We wanted the money back but he told us that it's mentioned on the website (it is hidden in the text). So you only can go hiking and of course you have to pay the additional 15 dollars parking fee. It's closed for swimming half of the time in summer - so be aware of this!

First off, you must have reservations to visit Hamilton Pool. This can be done on-line. It is a short hike. We were not able to swim due to bacteria levels were high, but just taking in the view was well worth the trip. Also, there are several hiking trails in the area. Worth visiting!

Some friends told os to go here. And we drived for around 300 miles and was very excited to get here. But when we arrived we meet a sign with no swimming at all and a lady who said we even couldn't go there because we should had made an reservation. So waste off time and very disappointed.

I don't like a lot of people but my kids like a good waterin' hole to swim in. I do, however, like my kids, so that's how we wound up at the Hamilton Pool Preserve on a hot summer day.

A PEOPLE HATER'S GUIDE ON HOW TO KEEP COOL AT HAMILTON POOL

1. Accept it deep within your soul that this place is going to be crowded. Do not fool yourself by the Instagram pictures that make it look like it's a magical hidden spot that only you and a handful of locals have stumbled upon. If you are reading this, you are probably a tourist so mentally prepare yourself to have fun with the other tourists.

2. How did I know it was going to be crowded? Honey, this place requires you to make a reservation to get in and every summer weekend was already booked way back in March. Yes, you need a reservation - don't be one of those fools who thinks they can get in, makes the hour drive from Austin, then gets turned away at the entrance.

3. Get there early for your reservation, like 10 minutes before, so you can sit in the car line, wait for fools to turn around, park your car, use the rustic stank-hole-in-the-ground that passes for a public restroom and then hike down to the pool.

4. Wear shoes that can go down rocky steps. Flip-flops are ok, but they slow you down because you want to make it to the beach to claim your spot.

5. The beach is really just a small strip of gravel, and it fills up fast. Go all the way to the end if you want a little bit of shade. I saw people who had just towels (not beach chairs or coolers) set up on the rocks under the cave-like overhang.

6. Glass containers and public display of alcohol are not allowed, so put your cocktail in an insulated cup. People are much more bearable when your drink is cold.

7. Do take a moment to walk behind the waterfall and admire how cool nature is. If you squint, all the people look just like dots.

8. The pool closes half an hour before your reservation time ends (so 5:30 for a 6 pm end time). Most people start making their way out at 5. We waited till the very last minute and had a few minutes of the entire pool to ourselves. It was very lovely and still.

If you can wait till then... bam! Instagram picture! Fool everyone else into thinking that they too can have a lovely, people-free time in this unique, special piece of nature.

PS - My kids had the best time, swimming and jumping off the rock by the waterfall.
