One of the special attractions in San Francisco, the structure of the prison at that time still exists, and the voice guide part is very vivid, as if it is on the scene. In addition, the fare to Alcatraz is not cheap. If you have to stay in San Francisco for a few more days, you can buy a package of Alcatraz and citypass cooperation, which will be cost-effective! Remind, because you have to take a boat back and forth, remember to check the time of the back and forth in advance, so you don't miss the long wait.
