Jewel Cave is one of the longest known caves in the world, with over 220 miles of mapped passages lined with calcite crystals. All cave access is by ranger-led tour, most popularly the Scenic Tour with hundreds of stairs, while the visitor center and surface trails are free. Tours sell out in summer, so reserve ahead on Recreation.gov and bring a jacket, as the cave stays cool year-round.
