Big Room
A self-guided walk past giant formations.

A vast limestone Big Room, one of the largest in North America, reached by trail or elevator, and hundreds of thousands of bats at dusk.
Below New Mexico's desert lie more than 100 caves. The Big Room's 1.25-mile path passes giant stalagmites and the Hall of Giants.
From spring to fall, Brazilian free-tailed bats swirl out of the cave's mouth at sunset, watched from a small amphitheater.
