Eureka Mountain Mine Ride, Steel roller coaster in Gold Coast, Australia

The Eureka Mountain Mine Ride was a steel roller coaster at Dreamworld on the Gold Coast in Queensland, Australia. It ran through an enclosed artificial mountain structure with tubular tracks, sharp turns, and steep drops, with cars that seated four riders in two rows.

The Eureka Mountain Mine Ride opened on 11 December 1986 alongside the Thunder River Rapids Ride, forming part of Dreamworld's new Gold Rush Country land. It closed for maintenance on 7 November 2006 and never reopened. The ride was built by Brisbane-based HyFab as a Wild Mouse coaster enclosed in Eureka Mountain; in 2002 dual-station loading ended and in 2004 the ride system was upgraded.

The queue and entrance were later converted to house carnival-style games, while the ride itself stood unused. Inside, cars climbed a chain lift hill before an animatronic miner lit a stick of dynamite; after the explosion, riders passed through sharp hairpin turns and steep drops.

The ride no longer exists: the track was demolished in December 2017 after a third-party assessment found it deteriorated, so there is nothing left to board. The queue and entrance had earlier been converted to house carnival-style games. Visitors to Gold Rush Country today see the site where the enclosed mountain once stood.

The ride was built by Brisbane-based HyFab, and its queue and entrance stayed in use for 11 years after the 2006 closure, housing carnival-style games. In 2015 water dummies were seen at the entrance and cars were cycled through the track during speculation about a reopening.
