Carlsbad Caverns
At dusk, hundreds of thousands of bats spiral upward from a hole in the desert floor.
The natural entrance yawns out of the Chihuahuan Desert and you walk down, hundreds of feet down, through air that turns from dry heat to damp cool in a few switchbacks. Then the Big Room opens around you, a chamber so vast the ceiling simply disappears.
Carlsbad Caverns hides more than 119 known caves, dissolved out of a fossil reef by sulphuric acid rather than the usual patient water, which is why the chambers run so vast. The Big Room, roughly 4,000 feet long with a ceiling arching 255 feet overhead, is walked on a paved loop in about ninety minutes of dumbfounded silence, and timed-entry tickets govern the descent. The theatre happens back on the surface: each summer evening from April to October, Brazilian free-tailed bats pour out of the natural entrance in a rising spiral, watched from an amphitheatre as rangers narrate, free and unbooked, with the biggest flights in August and September when the year's pups join. Below ground it is 56 degrees Fahrenheit forever; above, the desert cools and the bats go to work.
Family
The Big Room's paved, lit loop takes every age underground safely, and the evening bat spiral beats any film you could have shown them.
Couple
Walk down through the natural entrance as the light dies behind you, then surface for an amphitheatre sunset with a quarter-million wings.
Solo
The deeper the trail, the thicker the silence; Carlsbad rewards the contemplative walker with the loudest quiet in New Mexico.
- Sulphuric acid, not water, dissolved these caverns from a fossil reef, which is why the chambers run so enormous.
- The Big Room's paved loop crosses a chamber roughly 4,000 feet long beneath a 255-foot ceiling.
- From April to October, free-tailed bats spiral out of the natural entrance each evening, with rangers narrating from the amphitheatre for free.
- The cave holds 56 degrees Fahrenheit year-round, the most reliable cool in the New Mexico desert.
