This cave is located 35 km from Millau and around 70 km from Montpellier. Grotte de Labeil is the most southerly of the caves at Larzac and is crossed by an underground river. It is situated at 700m above sea level and its natural entrance was once used for making Roquefort cheese. The sight and sound of the illuminated water is unique and you can follow the river to easily reach this living cave’s richly coloured network of crystals. Guided tours are available.

The cave is apparently 7,000 years old and they organize a special viewing for families with children which my kids loved. They basically give you helmets and a map of the cave and let you go off by yourself for an hour. (Lara Gobourne)
