Today, the island's facilities are managed by the National Park Service as part of Golden Gate National Recreation Area; it is open to tours. Visitors can reach the island in a little under 15 minutes by ferry ride from Pier 33, located between the San Francisco Ferry Building and Fisherman's Wharf, San Francisco. Hornblower Cruises and Events, operating under the name Alcatraz Cruises, is the official ferry provider to and from the island.[from wikipedia]

There are several reasons that Alcatraz closed as a penitentiary in 1963: The penitentiary cost much more to operate than other prisons (nearly $10 per prisoner per day, as opposed to $3 per prisoner per day at Atlanta);[34] half a century of salt water saturation had severely eroded the buildings; and three people had escaped in 1962.[from wikipedia]

The earliest recorded private owner of the island of Alcatraz is Julian Workman, to whom it was given by Mexican governor Pio Pico in June 1846, with the understanding that Workman would build a lighthouse on it.[from wikipedia]

Alcatraz Island is home to the abandoned prison, the site of the oldest operating lighthouse on the West Coast of the United States, early military fortifications, and natural features such as rock pools and a seabird colony (mostly western gulls, cormorants, and egrets).[from wikipedia]
