There is no entrance fee to visit Alcatraz Island. However there is a charge for the ferry service to and from the island which is supplied by a private company under contract with the National Park Service. For additional information on schedules, prices, and to purchase tickets in advance (tickets are made available about 60 days in advance) please visit the Alcatraz Cruises website.
The price includes the cellhouse audio tour, which is available in English, German, French, Italian, Japanese, Mandarin and Dutch. If you do not wish to do the audio tour you can receive a refund by contacting a supervisor in the cellhouse bookstore.
