Get the most out of your day in the City by the Bay with this 2-day combo package, which combines a trip to Alcatraz with a San Francisco bike tour. On your first day, take a ferry to Alcatraz Island, and get access to the former federal prison. Go on a self-guided audio tour of the grounds, and stay as long as you like during opening hours. Then, on your second day, choose between three different guided bike tours to explore the city on wheels. Stop by lesser-known spots only locals know of and famous landmarks you’ll want to snap pictures of.
