Things To Know Before You Come
The weather on Alcatraz can be some what unpredictable and can change quickly - it may be warm and sunny in the city and very windy and cool on the island. Summer days can sometimes be as cool as winter due to thick fog and strong winds. We recommend dressing in layers.
There is no food service available on the island - only water is available on site. Eating, drinking and smoking is only allowed at the dock level.
Be aware that Alcatraz is a sanctuary for thousands of seabirds - feeding or disturbing any wildlife is not permitted.
As Alcatraz has no entrance fee park passes do not apply - charge is for the private ferry service to and from the island only.
It is the responsibility of visitors to understand and comply with all applicable state, local, and federal firearms laws before entering this park. See our Laws & Policies page for additional information.
Did You Know?
The abundant plant life found on Alcatraz today is not quite “natural” – originally the island was a barren, wind swept, bird guano covered piece of sandstone rock. Soil and plants were introduced by the U.S. Army as they built the first U.S. fort on the West Coast, beginning in the 1850s.
