The hook
The most famous prison in America sits on an island in the bay, and its fullest story isn't the cellblock but the nineteen months a group of Native activists held it.
01Why it's worth it
Alcatraz was a federal penitentiary from 1934 to 1963, the end of the line for men other prisons couldn't hold: Al Capone, Machine Gun Kelly, the Birdman. The 1962 escape is the legend, when Frank Morris and the Anglin brothers left papier-mâché heads in their beds, slipped out through a vent, and vanished into the bay, never found. But the part most visitors don't expect is what came after the prison closed. From 1969 to 1971, eighty-nine Native Americans occupied the island for nineteen months, claiming it under an 1868 treaty, and that stand helped launch a national Indigenous-rights movement; you can still read their painted words on the walls. It's the most touristed thing in the bay, more than a million people a year, and worth it anyway: the cellhouse audio tour, narrated by former guards and inmates, is one of the best in the country, and the boat ride and island gardens come with it.
02How to experience it
Ferries leave from Pier 33, and only the official concessioner lands on the island, so book well ahead, especially for the night tour, which is quieter and better. Give it a half-day with the crossing. Wear layers, the island is cold and wind-blasted even in summer, and the walk up to the cellhouse is steep.
