The Grottes du Cornadore (Caves of Cornadore) look like natural caves with speleothems, but actually these are underground Roman baths, fed by two thermal mineral springs of 22 °C. The Romans used the sulfur rich springs for medicinal purposes, the arsenic and lime was thought to cure kidney diseases. They constructed baths inside the cavern, two of which are shown on the tour. The cave is located in the granite complex of Saint Nectaire, which means there is no geologic process which could form such caves naturally.

The caves contains numerous speleothems. They formed during the last 2,000 years from the mineral rich water entering the caverns. There are limestone formations like stalactites and stalagmites, but also pisolites (cave perls) and aragonite flowers. Wooden water channels and staircases are covered by limestone deposits and look like petrified.
