By Ferry from Alcatraz Island to Pier 33 San Francisco.
The Alcatraz Federal Penitentiary or United States Penitentiary, Alcatraz Island (often just referred to as Alcatraz) was a maximum high-security federal prison on Alcatraz Island, 1.25 miles (2.01 km) off the coast of San Francisco, California, which operated from 1934 to 1963.
Today the penitentiary is a public museum and one of San Francisco’s major tourist attractions, attracting some 1.5 million visitors annually. The former prison is now operated by the National Park Service’s Golden Gate National Recreation Area, and the badly eroding buildings of the former prison have been subject to restoration works in recent times and maintained.
