Big Room Trail, Carlsbad Caverns National Park, New Mexico, USA
It takes about an hour and a half to encircle the Big Room—the largest chamber within Carlsbad Caverns and the largest single cave chamber by volume in North America. This 1.25-mile walk twists among giant stalagmites on a paved trail with handrails. A ranger-guided tour provides insight into the geologic history of the cave system.
