Ferry to Angel Island?

Question

Hi, if you're traveling to Angel Island on a summer weekday, should you worry about the 9:25 ferry filling up or is it a service that always has extra seats? Should you worry about the ferry filling up on a weekend?

Answer

Taking the ferry to Angel Island is a fantastic way to spend a San Francisco summer day, but capacity and crowds do vary by season and day of the week. The 9:25 AM ferry is a popular departure, especially during summer, when both locals and tourists head out early for hiking, biking, and avoiding afternoon winds.

Below is a detailed breakdown of what to expect on weekdays versus weekends, how often ferries fill up, and the best strategies to make sure you get the trip you want.

WILL THE 9:25 AM FERRY FILL UP ON A SUMMER WEEKDAY?

Generally, the 9:25 AM Angel Island ferry on a weekday is unlikely to completely fill up, but it can be quite busy in July and August. Weekday morning sailings typically attract:

Hikers wanting cool morning temperatures
Visitors from out of town
School or camp groups (especially June)

While weekday ferries do not sell out as often as weekend ferries, there are occasional full boats. Buying tickets in advance is recommended if your schedule is tight or you want guaranteed boarding.

WILL THE 9:25 AM FERRY FILL UP ON SUMMER WEEKENDS?

Yes—weekends are significantly busier. Summer Saturdays and Sundays are peak visitation days, especially when weather is clear. The 9:25 AM boat is the most popular because:

It gets you to the island early, before afternoon winds pick up.
Many hikers want to start before the heat and crowds.
Bikers prefer the early ferry to ensure rental availability.

Weekend ferries often reach capacity, especially in late June through September. For weekends, you should always purchase tickets in advance.

DO FERRIES ADD EXTRA SAILINGS?

Angel Island Ferry and Golden Gate Ferry sometimes adjust schedules seasonally but do not add unscheduled departures when a boat fills up. Once the boat is full, that’s it until the next scheduled time. This is why advance booking is important for weekends.

BEST PRACTICES TO AVOID FERRY ISSUES

Buy tickets in advance for all weekend trips, especially the 9:25 AM ferry.
Arrive 20–30 minutes early on both weekdays and weekends. Boarding may begin early, and lines can form.
If flexible, choose a weekday — fewer crowds and easier return-trip planning.
Check the return ferry schedule — some days have limited afternoon return times.

ADDITIONAL TIPS FOR A SMOOTH VISIT

Bring layers: Morning fog can be cool even in July or August.
Pack food or snacks: On-island options are limited and seasonal.
Midafternoon winds are strong: Early ferries are safer for good weather and calmer seas.
Check for special events: Races, group hikes, or festivals can cause ferries to fill.

SUMMARY

Weekday summer morning ferries rarely sell out but can be busy, while weekend ferries very often fill up during peak season. If you're traveling on a weekend—or want guaranteed space—booking your tickets in advance is the best choice.
