Mystery Mine is a steel roller coaster located at Dollywood amusement park in Pigeon Forge, Tennessee.

Opened in 2007, the roller coaster was Dollywood's largest single investment in the park's history at the time, costing $17.5 million to construct.

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.

According to Dollywood, Mystery Mine would feature state-of-the-art special effects, dark ride elements and mineshaft theming.

For the ride system, the park hired Gerstlauer to build a custom variation of the Euro-Fighter coaster model — the first of its kind in the United States and the first to feature two vertical lift hills.

As the car slows to a stop, a crow caws loudly from somewhere above and a small lever labeled "mine gas" cranks into the on position.

A green lantern suddenly illuminates, sitting on top of a mound of dynamite in boxes, hooked to the quickly approaching fuse.

On July 11, 2020, three park guests were walking on a pathway that trails underneath a bridged part of the ride when a decorative chain gave way and fell on top of them.

One of the guests suffered from a laceration on her forehead and injured her arm, the other woman was also taken to a hospital in an unknown condition, and the third person was treated at the park.
