About
Alcatraz Island, also known as The Rock, is a former federal prison on an island in San Francisco Bay, in California. It is now a National Historic Landmark and one of the best-known sites in the city.
What the island is
The prison operated from 1934 to 1963. Today the island is visited for its historic buildings and for what they say about the years when it held prisoners. The island sits in the bay, so the visit itself is a short crossing by boat, and the views back toward the city are part of the experience.
What to expect
- A landmark site on an island in San Francisco Bay, reached by water
- A former federal prison, preserved as a National Historic Landmark
- Views across the bay toward the city
Because the island is reached by boat, plan for the crossing and allow enough time to explore the site at a relaxed pace. Visitors who want to know more before they go can call the site at +1-415-561-4900.
