Situated about 13 miles from the town of Custer in the Black Hills, Jewel Cave National Monument protects and showcases the third longest cave network in the world, where you can explore some of the staggering maze of over 180 miles of mapped subterranean passages. Jewel Cave is irresistible to adventurers, explorers, and geologists and, depending on your level of fitness, there are several ways to explore its splendor.
The Scenic Cave Tour is considered to be moderately strenuous (lots of stairs), but it follows a paved walkway through several lighted caverns and passages. People with mobility restrictions can take advantage of the shorter, (accessible) Discovery Tour, while dare-devils can tackle the Wild Caving Tour, which requires you to scramble, crawl, and squeeze through some narrow tunnels and passages with your own headlamp. Up on the surface, you can hike several trails, do some bird watching, or admire the wild flower meadows. Photo: Jewel Cave National Monument
