Jewel Cave National Monument offers visitors a chance to explore the world’s third longest cave, consisting of more than two hundred miles of surveyed and mapped passages that appeal to the human curiosity. The splendor of Jewel Cave is revealed through glimpses of vivid color and fragile formations. In order to discover the underground wilderness, adventurers will need to join a ranger-led cave tour, with tickets offered on-site on a first-come, first-serve basis. It’s advised that visitors arrive early and get their tickets for the day in the morning, as they often sell out during holiday weekends or peak season.
