Pretty little lake in the heart of the small Jura mountains

Beautiful, simple, easy walk; lots of traffic noise on the "road" section, a bit of a shame, but the color of the water is magical

A 10 km climb from the small roundabout in Châtillon, it's more like 14 km from the Nantua road or the center of Bellegarde. The gradient is fairly steady, ranging from 5.5% to 7.2%, with about ten small steep sections at +8.5%. Very quiet, with very few cars. The road is generally in good condition, but nothing more. There are some beautiful views along the way.

The Col de Bérentin connects the Valserine Valley to the Retord Plateau, passing through the beautiful Jura forests. Its ascent is gradual and the road is little traveled.
