Alcatraz Island

Alcatraz sits on a rocky island in San Francisco Bay, a former military fortress turned into the most notorious federal prison in America, holding the likes of Al Capone in cold isolation surrounded by cold, current-swept water. Abandoned since 1963 and now a museum, its cell blocks and haunting audio tour make it one of the city's most gripping visits.

What you actually see

• The cell blocks - the rows of cells with the acclaimed audio tour by former inmates and guards.
• The famous cells - the escape attempt cells and solitary confinement.
• The island and views - the gardens, ruins and the San Francisco skyline across the water.
• The history - from fortress to prison to Native American occupation.

When to go

Year-round; the island can be cold and windy in any season, so bring a layer. Tickets sell out days or weeks ahead, so book early. Night tours offer a more atmospheric experience.

Honest expectations

You must book the official ferry and tour well ahead, as it regularly sells out, and there is no other way onto the island. It is cold and windy on the bay even in summer. The audio tour is excellent but the visit is a set, timed experience.

Nearby

Fisherman's Wharf and Pier 33 are the departure point; the Golden Gate Bridge and the city spread around.
