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

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.
