The tour of the lakes is not of much interest, mainly being wide paths, without much relief, and with no view worthy of the name, including on the lakes (which we see very little, except on the eastern part, which is a shame). The western part is even difficult (we follow the road for 2km...). In short, a walk to forget, except perhaps for a running outing, or a detour via the Eagle peak.

A magnificent hike from the parking lot of the first lake via the Pic de l'Aigle and then the Belvederes overlooking the lakes, a magnificent site

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.
