While cave tours have been suspended since December 2020 for construction at press time, they were expected to resume in mid-June. There are no self-guided tours here, and visitors must be accompanied by a ranger at all times experiences range from Historic Lantern Tours to wild caving tours. Nine bat species call this dark underworld their home, including the Northern long-eared bat, which has been designated as “threatened” under the Endangered Species Act. Nestled beneath the iconic Black Hills of South Dakota, in the southeastern corner of the state, the cave remains relatively intact and unchanged, according to the National Park Service, and the great bulk of it has yet to be explored.
Stalactites are relatively rare here instead, you’ll see plenty of other types of speleothems, including the sheet-like decorative flowstone, milky soda-straws (hollow tubes) and popcorn, often a cave-hunter’s favorite. This gem of a cave-at 208 miles, the world’s third longest-gets its name from the ruby- and amber-hued crystalline calcite spars that glitter everywhere you turn. Above ground, another 45 animal species, from white-tailed deer to mink to bobcats, roam the nearly 53,000-acre park. You’ll likely encounter a bat or two in the dark passageways, of course.
Highlights include landmarks such as a historic saltpeter mining site and a 40-foot-long boulder known as Giant’s Coffin. Need more superlatives? According to UNESCO, the cave features the world’s richest assemblage of underground wilderness, including 14 species of subterranean critters-troglobites (such as crustaceans) and troglophiles (frogs, salamanders)-that can be found only here.Ĭhoose from several guided tours, when available, or venture into the cave system on your own, beginning and ending at the historic entrance, a natural opening that’s been used for some 5,000 years. Its complex network of cave formations-chambers, shafts, and delicate gypsum “flowers” and “needles”-displays a greater variety of sulfate minerals, including mirabilite, epsomite and celestine, than any other place on (or under) the earth. This World Heritage Site in west-central Kentucky is the world’s longest cave system, winding beneath lush forests and fish-filled streams for nearly 300 miles.
