There is a small island 3 km from Fishermans Wharf, which used to be a federal government prison. From 1934 to 1963, it was the place where criminals, bank robbers, and prisoners were imprisoned. Many famous criminals such as Al Capone, machine gun Kelly (George Celino Barnes) and birdman Robert Stroud have all been closed here. Although Alcatraz prison claimed that criminals had never escaped successfully, three people had escaped because they needed to cross the waters with many undercurrents and sharks, so no one knew if they had survived. All the windows of Alcatraz Island Prison are not facing San Francisco. On Thanksgiving Day, the joy of the city hits the reef and then passes through the window to the prison. Many prisoners can't stand this mental torture. There are a lot of film sources or shots here, such as "Dragonfly Island". Tips: 1. Book tickets at least two weeks in advance. When you go to jail, you will get a device with audio guides and Chinese service.
