Absolutely! The biking portion of the Alcatraz Island tour package comes with our daily guided bike tour, all-day bike rental, and bottled water. If you want to skip the guided portion and go on your own, though – no problem! You can still get the all-day bike rental and bottled water, then go on a self-guided biking adventure. Come to our 2715 Hyde Street location with the guided bike tour voucher from your confirmation e-mail, and just let us know you want to go self-guided instead.
