A great spot for ibex! This area is home to many chamois and ibex, a species reintroduced in 1983 by hunters and EDF during the construction of the Grand' Maison Dam. The 7 Laux, despite what their name suggests, are actually 10: Lake Sagne, Lake Corne, Lake Jeplan, Lake Agnelin, Lake Cos, Lake Blanc, Lake Cottepens, Lake Carré, Lake Motte, and Lake Noir.
As you follow the lakes, you’ll cross the Belledonne Massif.
Marking : The trail is part of the Tour des Sept Laux, a yellow/red GRP®.
Good plans : For the return trip, you can take an alternate route via the Col de la Vache; this involves a descent of 1,200 meters.

Delicate passages : The route is equipped in places with concrete steps and cables, which can be useful on the descent. To be avoided on rainy days, as some sections are slippery.

Admission fee : Free access.

Opening : From 01/05 to 31/10 daily. Subject to snow conditions.

Step by step description : Shortly after Rivier d'Allemond, park on the old Croix de Fer Pass road, which branches off to the left and ends in a dead end, in front of the massive rockslide that forced its reconstruction on the opposite slope. After Rivier, continue along the road for about 2 km until you reach the intersection of the old road (closed) and the new one, which winds down to the valley floor. The trailhead is at this intersection. The trail follows the mountainside for about 1 km, then climbs in tight switchbacks up the Combe des 7 Laux. At the top of the plateau, you’ll first come to Lac de la Sagne. The series of lakes takes you from the Oisans region to the Grésivaudan region.

Warning : As this route is potentially subject to severe damage due to major weather events and its viability may be uncertain, please enquire before embarking on it.

Area : Oisans
