An underground world of massive chambers and millions of bats beneath the Chihuahuan Desert of New Mexico.
The cave stays about 56°F year-round, so any season works. Spring and fall are most comfortable above ground; summer evenings bring the bat flights.
Summer weekends and holidays are busiest, and cave tours can sell out — reserve ahead.
Summer surface temperatures reach the 90s–100s°F with July–September thunderstorms. The bat flight program ends in the fall.
General patterns — conditions vary by year. Check current NPS alerts and road status before you go.
Distances are rough estimates to the closest entrance. Check road and ferry conditions before you go.
Campgrounds inside the park are booked through Recreation.gov, and many fill months ahead.
