Brouffier lake by way Bonniot.


Very nice hike starting in the woods, then following an impetuous steep mountain torrent, and going along beautiful waterfalls to reach a high mountain lake in a pasture. Please stay on the main trail, as you enter a rich but fragile area. Nature deserves to be protected.

Drive on the road of "Poursollet" and park at the fourth switchback. From there, turn right on the forest flat track nammed "Bonniot" (no-entry sign) which reaches the Louvet shed (where the wolves used to stand) and the very small lake of Prévourey. Cross the vale into the direction of the end of the combe. A trail starts on the slope in line with the river. While the slope is getting less steep, the trail comes closer the torrent and crosses it. Only few switchbacks to reach the other bank, and a right-side traverse up to the spillway. To go down, walk along the lake on your left and reach a little shed, where the way back begins. Cross the summit of "Brouffier", then walk down to the walking indication "Les Fontenettes". Turn left and left again arriving on "Chemin de Bégoud". Walk back "Chemin de Bonniot" to the car park.
