Hiking
Several million years ago, the Ain was lost underground, in a labyrinth of cavities, an underground gallery called "losses". Over time, the work of water erosion has done its work, and has nibbled the limestone and destroyed the vault of the underground gallery. It remains today a unique natural site where water makes its way between rocky piles and stone remains.

Hiking
A marked and laid out path allows you to follow the bubbling Ain river along narrow and deep gorges, rocks and waterfalls, all surrounded by forest.
