Jewel Cave National Monument
Jewel Cave is one of the longest caves in the world, with more than 200 miles of explored passages winding deep underground. It got its name from the sparkling crystals that line its walls like tiny jewels.
It is famous for its glittering calcite crystals that sparkle when a light shines on them. Explorers keep discovering new passages, so no one knows exactly how big the cave really is.
Sparkling Crystals
The cave walls are covered with shiny calcite crystals that look like frosting made of tiny gems. When a ranger shines a light, the whole passage seems to twinkle.
Exploring Underground
Visitors take an elevator down into the cave and follow rangers along lit walkways and stairs. The cave stays cool all year, so a light jacket feels good even in summer.
Bats and Wildlife
Small bats live in parts of the cave and help the outside world by eating lots of insects at night. Above the cave, the forest is home to deer, birds, and squirrels.
