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.
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.
