Les Mystères du Nautilus (French for "The Mysteries of the Nautilus") is a walkthrough attraction at Disneyland Paris in France. It is an updated version of the 20,000 Leagues Under the Sea walkthrough attraction that was at Disneyland in Anaheim, CA in the early 1950s, based upon the film of the same name. This attraction takes guests throughout the various rooms of Captain Nemo's submarine, especially those seen in the film. It opened on 4 July 1994. Summary The submarine is located in a lagoon near Star Wars Hyperspace Mountain. Guests enter what looks like a lighthouse, and proceed into the attraction through an underwater corridor. Although guests may believe they are visiting the submarine seen in the lagoon, the 'underwater tunnel' leads them into a show building hidden by tall green bushes. The winding staircase into the attraction helps to disorient guests so they do not realise this. Six rooms are visited inside the Nautilus: The Ballasts Compartment: This is a dimly lit room, with an open safe at the center. Inside the safe is the treasure Captain Nemo has gathered from his many underwater explorations. Ned Land's guitar from the movie is visible among the coins. Captain Nemo's Room: This cabin, complete with a bed and a bathroom, allows guests to have a look at the Captain's belongings and his collections of books and paintings. A mirror is displayed on the organ and guests can sometimes witness Nemo's reflection. A recreation of James Mason's face is actually hidden behind the glass. When lit, it becomes visible. The Charts Room: This room is the hub of the Nautilus, with staircases ascending to the wheelhouse and the main deck above (although these cannot be visited). Several charts are displayed, including one representing Vulcania Island, Nemo's lair in the movie. The Diving Chamber: In the center of this small chamber is a trap door leading to the bottom of the ocean underneath. Diving suits stand along the wall. The Main Salon: This is the heart of the Nautilus. Books, artifacts, and numerous treasures of the sea are gathered here. The Captain's organ stands on the far side and guests can see Nemo's reflection when staring at the mirror just above the keys. One window opens on the ocean's depths and allows guests to witness the attack of the giant squid. As it approaches, one can see its beak reach for the
