The complete route of an ancient underground river
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.
Are dogs allowed in the caves ?
Yes, but they must be carried or placed in a basket. Only small dogs
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.
