Jewel Cave gets its name from the many calcite crystals which were formed from acid-rich groundwater. The cave stretches to an impressive 140 miles, making it the second longest cave in the world. Jewel Cave was proclaimed to be a National Monument in 1908 by Theodore Roosevelt. This increased public interest for the cave’s many wonders. Big Duh is the largest room in Jewel Cave. It’s 570 ft long, 180 ft wide, and 30 ft tall. There are various tours which will allow visitors to see Big Duh and other Jewel Cave sights. Scenic tours, Jewel Cave Discovery, Lantern tours, and Spelunking tours are all designed for the viewing of Jewel Cave. Tours should be booked in advance. Jewel Cave is open daily except for Thanksgiving, Christmas, and New Years Day. Visitors should be in good physical health when exploring the cave.
