The Haunted Mansion

The Haunted Mansion is a Dark ride attraction located at Disneyland Park, Magic Kingdom, Tokyo Disneyland, Disneyland Park and at Hong Kong Disneyland, although each location differs in design. Riders go through a haunted mansion resided in by "999 happy haunts."

The Haunted Mansion features a ride-through tour in Omnimover vehicles called "Doom Buggies", and a walk-through show is displayed to riders waiting in the queue line. The attraction utilizes a range of technology, from centuries-old theatrical effects to modern special effects featuring spectral Audio-Animatronics. The Haunted Mansion has inspired two similarly themed attractions, Phantom Manor and Mystic Manor, which exist at Disneyland Paris and Hong Kong Disneyland, respectively.
