The legendary Queen Mary first sailed in 1936 as the world's largest and most extravagant luxury cruise ship. In World War II, the Queen Mary was drafted as the largest and fastest troop ship to sail. It is now one of the most famous ships in history and is rumored to be haunted. A number of guided tours, along with a self-guided tour, are available daily. In October, celebrate Halloween with Queen Mary Shipwreck, a popular Southern California event featuring a number of mazes and live entertainment aboard the allegedly haunted ship.
