The Descent into Wonders
A well… or, rather a chasm… It is the first time that this incredible cave opens up before you.
This chasm is nothing other than an immense, vertical, vertiginous doorway that invites us to pass, in a few minutes, from the outside world to the underground world.
It is an entrance to a world that hides a thousand surprises and a thousand discoveries, and that doubtless hides just as many mysteries today…
All that is left is to go down…
Step by step, we go down to where we had never adventured before.
A Vision of the Heart of the Earth
What do the insides of the earth look like?
As you go down, the atmosphere changes. The light dims, and is replaced by gentle humidity; the temperature is a stable 13°C all year round. Those features allow unusual vegetation to develop.
There is no doubt about it: the opening is spectacular.
Édouard-Alfred Martel, visionary explorer, wanted to report on this unique image that had ever been seen before.
At 103 metres below the surface, a river stretches away and leads us into underground meanderings… There is no more sky, but a succession of vaulted chambers, each one breathtaking.
