Fastest & Scenic route from Palm Springs to San Diego

Question

My husband and I are visiting Palm Springs in July (we're from Memphis so the dry heat is much preferred over our 100% humidity:) and we are planning to drive to San Diego for the day. We plan to leave around 6 am on a Monday and return by the afternoon. We're going so my husband can get some good tacos:) We prefer the fastest route (especially on the return to PS) but want to avoid as much traffic as possible and hopefully have a scenic route as well if it's possbile to have both a fast and a scenic route. Any advice would be greatly appreciated.

Answer

Driving from Palm Springs to San Diego in July can be both scenic and efficient if you plan carefully. Leaving early around 6 am is a great choice to avoid heavy morning traffic and make the most of your day trip. Here are some detailed suggestions:

Fastest route:

The quickest route is generally taking Interstate 10 West to Interstate 15 South directly to San Diego. This is approximately a 2.5–3 hour drive depending on traffic.
This route is efficient for your return trip as well, minimizing travel time while still being a smooth, mostly freeway drive.
Since you’re leaving early on a Monday, traffic through Riverside and on I-15 should be lighter, but be aware that near major junctions like Temecula or Escondido, congestion can build mid-morning.

Scenic options:

For a more scenic drive, you can take Highway 74 (Ortega Highway) west from Palm Desert to San Juan Capistrano, then connect to I-5 South to San Diego. This route winds through the mountains and offers desert and canyon views.
The Ortega Highway is twisty and slower, so it’s more suited for morning driving when your goal is scenery rather than speed. It adds roughly 45–60 minutes compared to the freeway route.
If you prefer a compromise, you could take I-10 and I-15 for the fastest route to San Diego, then explore some coastal views once in the city, like a drive along Mission Bay or Pacific Beach, before returning on the freeway for speed.

Tips to combine fast and scenic travel:

Depart Palm Springs at 6 am to maximize early freeway efficiency.
Consider using the Ortega Highway (Highway 74) for part of the drive if you enjoy desert and mountain scenery, but keep I-10/I-15 as your main return route to save time.
Plan your taco stop strategically in San Diego. Popular areas like North Park, Barrio Logan, or Old Town offer excellent options and are accessible without adding excessive driving time.
Use a navigation app to monitor live traffic conditions, as occasional construction or accidents can affect both freeway and scenic routes.

Overall, combining an early freeway departure with optional scenic detours allows you to enjoy the views while still making the day trip feasible. Leaving around 6 am should give you a stress-free drive and plenty of time to enjoy tacos and some quick sightseeing before heading back to Palm Springs.
