Questions sur les Grottes
  • What is the temperature in the cave ?
    • The upper gallery is at 13/14 °C and then drops to around 10 °C at the end of the large hall. For the second part, the temperature drops to 4 °C for 5 minutes. On the belvedere, you will find the outside temperature.


    • It is the temperature differences and the elevation that make this second part of the visit more physical.

  • Why a 2-part visit?

      • The main part corresponds to the concreted gallery and the path constitutes a loop with departure and arrival at the reception of the site. For people ready for an additional ascent effort, it is possible, at the end of the upper gallery overlooking the large room, to continue independently to the belvedere. This overlooks the Cerdon’s valley and its vineyards.
      • This second part with a higher elevation and therefore on the initiative of each and own rhythm.
    • Can we take a stroller in the caves ?

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