The 25-minute ferry ride to the island is a narrated historical tour of Alcatraz, discussing the construction and operation of the prison. The approach is typically longer than the return trip as to provide visitors a full view of the island during daylight hours. The boat docks where a National Park Service guide leads guests to the main prison building.
Tours of Alcatraz are not personally guided. Park service staff are available throughout the prison for questions, however, the tour is self-guided by way of an audio tour--"Doing Time: The Alcatraz Cellhouse Tour." The audio tour complements the numerous videos and exhibits on the island, including a cell door demonstration. The ferry leaves the island each evening at approximately 7:10 p.m., docking by 7:25 p.m.
The National Park Service describes the night tour as a more guided experience. Day tours are less structured and more areas of the island are open for exploration, including the island walks and bay vistas. Evening tours include the guided tour from the dock to the prison. Evening tours also feature exclusive programs not available during the day. These change frequently, with a schedule available from the National Park Service.
Evening trips to Alcatraz are available only from Thursday through Monday of each week. Daytime tours are available each day.
