🌲 Park Overview

Beneath the Chihuahuan Desert of southeastern New Mexico lies a subterranean wonderland: Carlsbad Caverns National Park. More than 119 limestone caves—formed when sulfuric acid dissolved ancient reef rock—house giant stalagmites, delicate soda straws, and chambers so vast they could swallow city blocks. Aboveground, the Guadalupe Mountains’ desert landscape explodes with agave blooms and nightly bat flights. Whether you’re descending the natural entrance into the colossal Big Room, witnessing hundreds of thousands of Brazilian free-tailed bats swirl into twilight, or hiking quiet desert canyons, Carlsbad Caverns offers underground awe and star-bright solitude.

🌟 Fun Facts

The Big Room spreads across 8.2 acres, making it North America’s largest single cave chamber by volume.

Carlsbad’s caves were carved not by dripping water but by sulfuric acid rising from petroleum deposits below.

Up to 400,000 bats emerge each summer evening—one of the world’s premiere bat flights.

Nearby Lechuguilla Cave (in park) is over 150 miles long and famed for its rare gypsum chandeliers—entrance is research-only.
