A guided tour with commentary takes you through a network of galleries and rooms on different levels. Several scientific disciplines are covered: geology (the cave’s formation); palaeontology (galleries containing bones) and prehistory through the attested presence of several cultures: Aurignacian, Magdalenian and Azilian; not to mention history (the Wars of Religion).

The palaeontological aspect is also tackled, with the ossuaries that can still be seen on the upper floors – they plunge the visitor into the specific ice-age environment of the fauna, as impressive as they are varied (mammoths, woolly rhinoceros and cave bears).

The "mask" - E. Demoulin

An important prehistoric settlement, the cave also includes several decorated galleries that contain some extremely interesting figures, but they cannot be visited not only because they are very difficult to access, but also to ensure their conservation.
