Carlsbad Caverns National Park and its underground chambers
Published on 09/23/2026 at 22:27 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Carlsbad Caverns National Park extends from the Chihuahuan Desert into a limestone world beneath the Guadalupe Mountains. Its central feature is Carlsbad Cavern, where enormous chambers, mineral formations and a natural entrance create a landscape unlike the desert above.
Carlsbad Cavern: a landscape beneath the desert
Carlsbad Cavern belongs to a much larger underground system. The park contains more than 100 limestone caves, while its surface includes desert terrain, limestone ridges and parts of the Permian Basin. The caves formed within an ancient fossil reef created by an inland sea about 265 million years ago.
The reef is associated with the Capitan Reef, a geological formation extending through southeastern New Mexico and western Texas. Marine fossils remain in the limestone, linking the underground chambers to sponges, algae, shells and other life from the Permian Period.
Inside Carlsbad Cavern, the Big Room forms a vast underground chamber with a ceiling rising to about 77 metres (253 ft). Stalactites hang from the roof, stalagmites rise from the floor, and other deposits cover walls, ledges and passages with mineral textures.
From Permian reef to protected national park
Carlsbad Caverns National Park was established as Carlsbad Cave National Monument on 25 October 1923, when President Calvin Coolidge signed the founding proclamation. Congress designated the area a national park on 14 May 1930. These dates mark the transition from protected monument to national park.
The cave also has a human history connected with exploration, photography and guano mining. James Larkin White entered the cavern in 1901, and mining began in Carlsbad Cavern in 1903. Ray V. Davis photographed the cave between 1915 and 1918, producing images that brought its interior to a wider audience.
In 1995, World Heritage status was granted to the park. The designation covers the underground caves, geological history and biological features associated with the protected landscape.
Lechuguilla Cave and the wider underground system
Carlsbad Caverns National Park is not defined by a single chamber alone. Lechuguilla Cave forms another major part of the park’s subterranean heritage, with passages that contain unusual mineral deposits and scientific information about cave development.
Exploration of Lechuguilla Cave expanded in 1986, revealing passages beneath the Guadalupe Mountains. Its deposits include gypsum, sulphur and other minerals formed through chemical processes in the limestone. The cave remains distinct from the areas prepared for public exploration.
The park’s geological story reaches from the Permian Period to the present shape of the Guadalupe Mountains. Rainwater, groundwater and dissolved minerals contributed to the formations found underground, while the desert surface preserves a separate landscape of dry washes, scrub and exposed rock.
Carlsbad Caverns National Park therefore joins several landscapes in one protected area: desert, mountain, fossil reef and cave. The most striking contrast lies between the open Chihuahuan Desert and the immense chambers below it.
Visiting Carlsbad Caverns National Park: what travellers from Western Europe should know
- Carlsbad Caverns National Park lies in southeastern New Mexico, near the city of Carlsbad and the Guadalupe Mountains. Road access connects the park with Carlsbad and the surrounding desert region.
- The natural entrance descends into the cavern on a steep underground route. The Big Room provides another route through the cave, with uneven surfaces, rock walls and substantial changes in elevation.
- The park includes desert terrain as well as underground passages. Surface conditions differ from the cave environment, and the landscape contains exposed limestone, dry vegetation and mountain slopes.
- The official language is English and the currency is the US dollar.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
