The ferry from Pier 33 out to the former federal penitentiary is one of the most memorable half-days in the city, and the award-winning cellhouse audio tour, narrated in part by former inmates and guards, is genuinely gripping. Beyond the prison, the island covers the 1969 Native American occupation, gardens, and superb bay views. Book through Alcatraz City Cruises, the only authorized operator, and reserve weeks ahead, as tickets sell out fast.
