Carlsbad Caverns, United States
Carlsbad Caverns contains over 119 known caves formed when sulfuric acid dissolved the surrounding limestone reef — a remnant of an ancient inland sea. The Big Room, at 8.2 acres, is the largest single cave chamber in North America. The natural entrance descends 750 feet through switchbacks past dramatic formations. From May through October, hundreds of thousands of Brazilian free-tailed bats spiral out of the cave at sunset.
Roamee Pro, also known as Roamee, offers a free self-guided Carlsbad Caverns walking tour with audio narration. Use it to explore The Big Room, Natural Entrance, Bat Flight Program, plus hidden gems like Slaughter Canyon Cave and Rattlesnake Springs without booking a group tour.
