Once a federal prison housing dangerous and notorious criminals, Alcatraz (The Rock) now welcomes tourists into the cell blocks once occupied by the likes of Al Capone, Machine Gun Kelley, and the Birdman of Alcatraz. Self-guided audio tours have dramatic narratives of Alcatraz’s grim history, including realistic sound effects one would hear in prison. Apart from the prison complex itself, Alcatraz Island essentially operates as a national park. You can spend a full day hiking, taking in the view from multiple observation points and appreciating the natural beauty.

A festival marketplace with 13 bay-view restaurants, dozens of fun attractions and over 110 stores, many one-of-a kind.

If you can’t find it here, you can’t find it anywhere.
