The history of the caves

Prehistoric Men very early chose the cavities of the site as a refuge. Excavations carried out since 1914 have uncovered multitudes of pottery, cut flint, huge heap of ash (4 to 5 m thick), quantities of animal bones as well as a human skull with prominent orbits.

These discoveries indicate that this natural shelter was inhabited since a very remote time (10 to 12,000 years).

Questions sur les Grottes
  • Can we visit the caves alone ?

    You can opt for a self-guided tour (reserved for groups of less than 8 people). Children are the responsibility of parents or carers. It is forbidden to leave the main path and touch the concretions.

  • Can we take a stroller in the caves ?

    No because of the stairs! Please note that we provide baby carriers for free.

  • Is there a restaurant in the touristic site ?

    • "Le Chasseur Cueilleur" offers snacks mainly based on local products as well as hot and cold drinks, to consume on the spot or to take away from the park. Open continuously throughout the day.
