From the 400-mile-long Mammoth Cave in Kentucky to a 2,000-year-old lava tube in Washington, there’s a whole world to explore beneath the surface of the United States.

With an estimated 45,000 caves around the country, subterranean adventures have no limit!

Whether you prefer creeping and crawling through less-developed caves, or learning history and geology on a guided tour past stalactites and stalagmites, these 10 most amazing caves and caverns around the U.S. will fulfill your desire to explore down under.

The 119-odd caves in this national park make up an underground world full of skinny dangling rock formations called soda straws, giant pillars resembling massive stacks of broccoli, and rocks covered in a bumpy “popcorn” coating.

General admission ($10 adults, free for children) grants you access to a self-guided tour through the caverns via an elevator, or a two mile trek down the Natural Entrance.

The tour includes the aptly named Big Room, which at the size of roughly 6.3 football fields, is the largest single cave chamber in north America.

Between May and October you can watch a show put on by the 400,000 Mexican free-tailed bats that call these caverns home. Head on over to the ​Bat Flight Amphitheater​ (free with park admission) ​around sunset and watch as they burst out of the cave and take flight into the night.
