California | San Francisco | United States
The Rock (now a National Park) was a famous federal prison where the worst of the worst criminals were kept. It was said when lavish parties in the 1920s occurred on the mainland, the prisoners could hear it from their cells way out at sea. The tour includes a cruise from San Francisco and audio tour of the cell blocks that’s great. The views over the city are fantastic. Tours leave from Pier 33. You MUST get tickets a head of time (usually months ahead). Do not miss your boat, they are not forgiving. Tickets for cruise and Island here: https://www.alcatrazcruises.com
