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.
