Alcatraz Federal Penitentiary

Alcatraz Federal Penitentiary was the high-security federal prison located on Alcatraz Island in San Francisco Bay, operating from 1934 to 1963. The facility held convicted criminals judged too dangerous or escape-prone for other prisons and became widely known for its strict regimes and famous inmates.

Contemporary visitor experiences focus on the cellhouse audio tour, the recreation yard, and other preserved structures such as the lighthouse and guard facilities; National Park Service interpretive programs present history, escape attempts and daily life at the prison. Access is by ferry from San Francisco, with timed departures and on-island routing managed by concessionaire ferry operators.

The island’s history predates the federal prison: it was used as a military fortification and military prison in the 19th and early 20th centuries, and the lighthouse on the island was first lit in 1854. After the penitentiary closed in 1963 the site entered National Park Service management and later hosted a famous occupation by Native American activists from 1969 to 1971.

Alcatraz Island sits about 1.25 miles (roughly 2 kilometres) offshore from downtown San Francisco in the central bay, visible from multiple waterfront points and reached by regular visitor ferries departing from Pier 33.

• Federal prison years: Operated as a federal maximum-security penitentiary from 1934 until its closure in 1963, housing some of the era’s most notorious inmates.
• Visitor access: Public access is by scheduled ferry service from San Francisco; the National Park Service runs guided and audio tours of the island and cellhouse.

What to See#

• Cellhouse: Cellhouse - The central prison building where cells, mess hall and administrative rooms remain the focus of guided tours and the audio tour narrative.
• Lighthouse: Alcatraz Lighthouse - Constructed in 1854 and located at the island’s highest point, the lighthouse predates the federal prison and is the first lighthouse built on the U.S. West Coast.
• Recreation yard: Recreation yard and parade ground - Open-air area behind the cellhouse where outdoor exercise and recreation took place and which is visible on standard visitor tours.

Alcatraz Island is served only by authorized ferry service from Pier 33 Alcatraz Landing in San Francisco (Alcatraz Cruises is the official operator); reservations are strongly recommended. Pier 33 is on the Embarcadero near Fisherman’s Wharf-reachable from downtown on the F Market & Wharves streetcar (to the Embarcadero/Fisherman’s Wharf area), by Powell-Hyde cable car to the Wharf and by numerous Muni bus routes; the walk from the Wharf/Embarcadero transit stops to Pier 33 is about 10-15 minutes. From San Francisco International Airport drive about 20-25 miles (≈32-40 km) to the Embarcadero via US‑101 or I‑280.

• Book ferry tickets with the official operator (Alcatraz Cruises) well in advance - day and especially night tours often sell out weeks ahead in summer.
• Take the first or early ferry from Pier 33 to avoid the largest tour-group crowds and get clearer views of the cell blocks before audio-tour traffic builds up.
• Follow the routing signs at Pier 33 and keep your ticket handy - the ferries depart from and return to Pier 33; many visitors miss the island's gardens and bird colonies if they rush straight to the cellhouse, so allow time to walk the island paths.
