Jewel Cave National Monument offers a unique chance to descend into one of the most beautiful subterranean caves in the United States. The monument is set within sprawling Black Hills National Forest and has been welcoming visitors since 1908. As the name suggests, the walls of Jewel Cave are dripping with sparkling calcite crystals. Guided tours take you deep into the cave and offer a behind-the-scenes glimpse of the mesmerizing underground world. So far, around 200 miles of the cave network have been surveyed. This is a minuscule three percent of the estimated total length, making Jewel Cave one of the longest known caves in the world.
Planning a getaway to Black Hills National Forest? Book an RV in Custer County and you can explore Jewel Cave National Monument at your own pace. You'll love sleeping under the stars in Black Hills National Forest, with more than 30 campgrounds to choose from. With a home on wheels, you can also venture further afield to other Midwestern recreation areas such as Badlands National Park.
