The Black Hills Caverns were discovered in 1882 by miners looking for gold, but Lakota Indians had already been drawing strength from the caverns’ calcite crystals for generations. This underground cavern is approximately 3,400 feet long and features more than a dozen rock formations, including helictites and popcorn crystals. Visitors can choose between two tour options; the first is the Adventure Tour, which takes roughly an hour and explores the Black Hills Caverns covering three levels of the cave in just under 1 mile. The second option is the Crystal Tour, an easy half-tour that explores the first level of the cave, or about 1,500 feet.
