Rush Mountain Adventure Park

Keystone, United States

---

Rush Mountain Adventure Park near Keystone, South Dakota, in the Black Hills close to Mount Rushmore, centers around Rushmore Cave discovered in 1876 by miners chasing gold, officially opened to tourists in 1927 as Hermosa Crystal Cave and renamed in the 1950s by owners Si and Ruth Pullen who added lighting, a gift shop, and an exit tunnel before selling in 2008 to expand into a full adventure hub.

Guests explore stunning stalactite caverns on guided tours through the Big Room, then tackle thrills like the Rushmore Mountain Coaster twisting down the slope, Soaring Eagle Zipline Ride, Wingwalker Challenge Course with tightropes and ziplines (plus kid Sky Tykes version), Gunslinger 7D interactive dark ride, gemstone mining sluice, and Sparky’s Snackitorium for snacks.

Family-friendly with unlimited wristbands for repeat rides, it blends underground wonder and outdoor adrenaline year-round, operating weekends in early spring for Black Hills explorers of all ages.
