Grotte de Labeil, Show cave in Lauroux, France.

Grotte de Labeil opens in Bathonian dolomitic limestone on the southern edge of the Larzac plateau, in the cirque de Labeil where the Laurounet rises. Its galleries run 1,885 metres, crossed by an underground river that resurges at the fontaine de Baume Baucart, at 620 m, below the entrance at 650 m. Inside, rounded brown and tan rock masses sit above the water, and a metal walkway with a handrail follows the wall.

Archaeological excavations in the 1960s revealed multiple layers of human occupation at the cave entrance, with evidence dating back 5000 years. These findings show that the site has been used as shelter and dwelling since prehistoric times.

The entrance once served to age Roquefort cheese, linking this place to the dairy traditions of the region. Visitors walking through can still sense this connection to southern French cheesemaking heritage.

The cave can be visited on foot through a natural pathway that is accessible from outside. Guided tours are offered to learn more about the formations and the site's background.

The cave's total mapped development is 1,885 metres, but the full survey of 1,815 metres of passages was only completed in 1985 and 1986 by Éric Elguero and Jean-Pierre Rouges of the Club Loisir Plein Air. Earlier work by the Spéléo-club alpin languedocien had opened the concretion network east of the river in 1972.
