A short walk through the footbridges and belvederes that line the Ain after its departure, magnificent scenery

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.

The Serpentine, (first tributary of the Ain river whose source is located a little higher) forms a small lake near the ruins of a mill. It is from a cornice that this beautiful natural waterfall 15 meters high comes to life when the water level is sufficient.

At the source of the Ain, you will find footbridges and interpretation panels to help you navigate and understand the site. A beautiful and relaxing place to take a break from your run.

The river seems to weave through cracks in the bedrock before flowing into a crystal clear pool. Amazing geography.
