- Mystery Mine
Mystery Mine is a steel roller coaster located at Dollywood amusement park in Pigeon Forge, Tennessee. Manufactured by Gerstlauer, the Euro-Fighter model is heavily themed as a haunted mining operation from the 19th century. The roller coaster was Dollywood's largest single investment in the park's history at the time, costing $17.5 million to construct. A large portion of the track is located indoor, where the ride utilizes a series of special effects. It was the first Gerstlauer Euro-Fighter installation in the United States and had the steepest drop of any coaster in North America at the time of its opening. The ride was installed by Ride Entertainment Group, who handles all of Gerstlauer's operations in the Western Hemisphere.
