Two popular San Francisco activities in one! The first tour includes the world famous Alcatraz Island Prison Tour. The tour also includes a 45-minutes audio tour in different languages. You can stay on the Alcatraz Island as long as you like, and catch any returning ferry back to the wharf.
The second part of this tour package includes the use of a bicycle to bike across the Golden Gate Bridge and/or anywhere you'd like to explore (self-guided). Each bike rental includes a helmet and a lock. The second activity can be done on the same day or on a different day.
