The hours of operation vary with the season - departures are available about every half hour throughout the day beginning at 9:00am. Evening tours and combined Angel Island - Alcatraz Island tours are also available seasonally. Alcatraz is open every day except Christmas, Thanksgiving and New Year's day. Alcatraz frequently sells out in advance, as much as a week or more in summer and near holidays. For schedules, prices, and to purchase tickets in advance please visit the Alcatraz Cruises website.
