Lac du Brouffier – A Picture-Perfect Mountain Hike
Lac du Brouffier is everything you could wish for in a mountain lake: crystal-clear water, pristine surroundings, and exceptional views. The perfect recipe for a memorable hiking adventure! On the way back via the Côte des Salières, you’ll be rewarded with a breathtaking 360° panorama: walk seemingly above the city of Grenoble, spread out just below your feet, and take in stunning views of the surrounding massifs — Obiou, Grand Serre, Vercors, Chartreuse, and Belledonne. A hike you’ll never forget!
Route:
From the resort, take the road to Lac du Poursollet. After about 4 km, park at the fourth hairpin turn. From there, take the flat path to the right named Bonniot (marked with a no-entry sign). This trail leads to the Cabane du Louvet (once home to wolves) and the tiny Lac de Prévourey. At the cabane, continue straight ahead — the path to Lac du Brouffier is also signposted to the left; this will be your return route.
Cross the valley towards the end of the combe. A determined path climbs along the stream’s axis. As the slope eases, the trail approaches and crosses the stream. A few switchbacks on the opposite bank lead you up the lake’s natural threshold, finally arriving at its outlet after a last traverse to the right. For the descent, follow the path along the left side of the lake (you’ll see it clearly) and veer toward a small cabin marking the start of the return trail. Climb slightly, then descend to the hiking signpost Les Fontenettes. From there, turn left in the direction of Cabane du Louvet and Lac de Prévourey.
Important!
You are hiking in a protected natural area. Please stay on marked trails, keep dogs on a leash, do not light fires, and carry your waste back with you or to the nearest bins. Respecting and preserving this environment is essential!

From the ski resort, take the "route du lac du Poursollet". After nearby 4km, park your car at the fourth hairpin turns. From theren take on your right the flat path called "Bonniot" (forbidden direction sign) which arrives at the "Cabane du Louvet" (place where wolves were) and one the small Prévourey lake. Once at the cabin, take the path in front of you : the Brouffier's lake is also announced on the left trail, it will be your way back.
Cross the dale towards the back of the hollow ; a trail attacks with determination the slope in the axis of the river. While the slope is weakening, the trail is coming closer to the river and cross it. In some switchbacks on the other shore, it swallows the rock bar of the lake of which it joins the spillway by a last cross on the right. The comedown goes by going along the lake on the left side (you see the trail) and away from a cabin where starts the way back. Keep following the trail which goes up and go down to the hiking pole "Les Fontenettes". From there, take on the left towards the "Cabane du Louvet" and "Lac de Prévourey".
