Alcatraz, San Francisco, USA
A small, isolated island in the chilly and hazardous waters of San Francisco Bay, Alcatraz became America's most famous prison. Beginning as a military prison in the 1860s, it was a federal penitentiary between 1933 and 1963, with Al Capone among the notorious residents. Visitors now can wander the abandoned and decidedly grim cells; lighthouse; early fortifications; and surprisingly beautiful natural environment. Be sure to opt for the self-guided audio tour, chillingly narrated by former inmates and prison guards.
California is also home to the Golden Gate Bridge, Hollywood, Yosemite National Park, and one of the world's best theme parks. If you are thinking about a trip to the 'Sunshine State', we have 7 reasons to visit California to help you decide.
