A rocky island in San Francisco Bay that was a fort, a military prison, a notorious federal penitentiary and the scene of a Native American occupation
Alcatraz rises from the middle of San Francisco Bay, its lighthouse and long concrete cellhouse visible from much of the city. The National Park Service describes it as a place that reveals stories of American incarceration and justice: it has been a fort, a military prison and a maximum-security federal penitentiary, and in 1969 it was occupied for 19 months by the Indians of All Tribes in the name of Native American civil rights.
The only way to visit is by the authorised ferry from Pier 33. From the dock a steep road climbs about a quarter of a mile to the cellhouse, where an award-winning audio tour narrated by former inmates and officers leads through the cell blocks. Around the buildings, restored gardens, ruins and cliffs used by nesting seabirds such as western gulls and cormorants show the island's quieter side.
Spanish explorer Juan Manuel de Ayala charted San Francisco Bay in 1775 and gave the name Isla de los Alcatraces to a nearby island; the name later came to be used for this rock. After California passed to the United States, the army fortified Alcatraz to guard the bay. A lighthouse was built, and by the outbreak of the Civil War in 1861 the island mounted dozens of cannon and also served as a military prison, a role it kept for decades. The concrete main cellhouse that still dominates the island was completed in 1912.
The Department of Justice took over in 1933, and Alcatraz opened as a federal penitentiary in August 1934 for prisoners who caused trouble elsewhere, including Al Capone and Robert Stroud, the 'Birdman of Alcatraz'. Over 29 years, 36 prisoners made 14 escape attempts; the most famous was made by Frank Morris and the brothers John and Clarence Anglin in June 1962. The prison closed in 1963 because of its high running costs. From November 1969 to June 1971 the island was occupied by Native American activists, an event the park presents as the birth of the Red Power movement. Alcatraz became part of the Golden Gate National Recreation Area in 1972 and was designated a National Historic Landmark in 1986.
For San Francisco, Alcatraz is both a visible daily landmark and a working part of the waterfront, with ferries leaving from the Embarcadero near Fisherman's Wharf throughout the day. The National Park Service uses the island to host programmes on justice and incarceration, including talks by formerly incarcerated speakers, and the Native American occupation remains an important chapter for Indigenous communities in the Bay Area. The annual Escape from Alcatraz Triathlon includes a swim from the island to the shore.
A visit begins with the ferry from Alcatraz Landing at Pier 33 and an orientation at the dock, where rangers and volunteers post the day's free programmes, which can include talks on the occupation, escapes and cell door demonstrations. Most visitors then climb the road to the cellhouse for the audio tour, available in many languages, and explore the exhibits, the recreation yard and the gardens at their own pace; plan on a few hours. Evening tours offer different programmes and views of the city lights, and Behind the Scenes tours visit areas not otherwise open. An electric shuttle helps visitors who cannot manage the steep climb.
Alcatraz is open year round except on Thanksgiving, Christmas and New Year's Day, but the weather on the island is changeable and often cooler than on the mainland, with fog common in summer and rain in winter. Tickets can sell out weeks ahead in summer and around holiday weekends, so spring and autumn weekdays are usually easier to book. Some areas close seasonally while seabirds are nesting.

Alcatraz Landing at Pier 33 is a short walk from Fisherman's Wharf and the rest of the Embarcadero waterfront. Combined tours also visit Angel Island, and the Golden Gate Bridge is clearly visible from the island and the ferry.
