Questions sur les Grottes
  • Can pregnant women, elderly people go down to the cave ?
    • The entire path through the caves is landscaped, marked and lit, but the elevation, the stairs and the temperature differences represent additional physical effort compared to a simple walk outside. It is up to everyone to judge their ability based on their physical condition, knowing that the first part remains very accessible.


    • The 2nd part of the circuit is the most physical.

  • I am accompanied by a person in a wheelchair, can I visit the caves ?
    • The entire reception area (ticket office, shop, snack point and toilets) is wheelchair accessible independently. The Caves of Cerdon cannot be visited in a wheelchair or with a stroller. The park is accessible with the help of a wheelchair attendant. The park's trails are mostly grassy..

  • 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.

Provide warm clothing for the visit of the caves (14°c to 4°c for 5/10 min) and comfortable shoes (return by a path in the undergrowth)
