This is an iconic landmark. Don't forget to visit Fort Point below on the SF side (free), and Fort Baker on the Sausalito side. I rented a bike at Fisherman's Wharf, visited Fort Point, rode across the bridge, visited Fort Baker, and rode into Sausalito. I took the ferry back to the Ferry building and had a great view of the Golden Gate Bridge, the Bay Bridge, of SF and of the seldom seen back side of Alcatraz. Great day, great adventure.
