Make your own way to Pier 33 in San Francisco to pick up your tickets and embark for the 15-minute ferry ride across the bay to Alcatraz Island. When you land on ‘the Rock,’ receive a brief history of Alcatraz, and then head into the cell block to learn about the former federal prison, now a national park. Via the provided audio tour 'Doing Time,' you'll hear interviews from former inmates such as Al Capone (Scarface) and Machine Gun Kelly. Expect to spend up to 2.5 hours on the self-guided audio tour; you can explore the prison grounds and stay as long as you wish before hopping back on the ferry to return to Pier 33. (Ferry departs approximately every 30 minutes.)

While in Fisherman's Wharf, head over to the Aquarium of the Bay to explore at your leisure and witness the 20,000 marine animals inside.
