West Texas & New Mexico
White gypsum dunes, a giant cave, the top of Texas and the dark-sky wilderness of Big Bend.
Best time to visit · New Mexico
A cave so big you can walk in through its natural mouth, and a nightly summer bat flight.
The best time to visit Carlsbad Caverns National Park is May–October. For great conditions with fewer people, aim for May, September and October. It's busiest in July.
Underground, it's 56°F year-round, so the cave is always comfortable. Above ground it's quiet and mild.
The bats return to the cave in April and May, and the evening bat flight programs start.
Prime time for the sunset bat flight, when hundreds of thousands of Brazilian free-tailed bats spiral out of the cave mouth.
Bat flights continue into October before the colony migrates to Mexico. The desert above is pleasant.
Walk in via the Natural Entrance (about a 1.25-mile steep descent) and ride the elevator out. It's the best way to grasp the scale.
Carlsbad Caverns' Big Room is the largest readily accessible cave chamber in North America, covering about 8 acres.
Before you go: The park has used timed-entry reservations for the cave. Phones and cameras are not allowed at the bat flight. Check current conditions on nps.gov.
Closest major airport: El Paso (ELP), about 2.5 hours.
