The Lac de Belledonne itinerary is one of the must-do hikes in the Eau d'Olle valley. The atmosphere is wild and the scenery magnificent, with the Belledonne range dominating the trail, including the Croix de Belledonne, and facing the Grandes Rousses and Rissiou massifs.

TECHNICAL INFORMATION:
Start: Coteyssart parking lot above Allemond.

Duration: 4 (outward/return)

ROUTE :
From Allemond, take the direction of l'Eglise, then the route de la Traverse to the Coteyssard parking lot.
The path starts at the bend above the track, crosses the Coteyssard stream and continues through the forest of the same name to reach the Chazeau hut (unguarded). This is the summer home of transhumant shepherds. After the hut, the trail crosses alpine pastures and blueberry bushes, then climbs to the Pas du Bessey via a moraine.
The path then descends slightly and crosses a vast scree, testimony to the passage of the glaciers under the Grand Charnier.
At the trail junction, turn left for the final climb to the lake. You pass 2 small lakes and a waterfall descending from the lake.
The lake nestles on this natural promontory.

THINGS TO SEE ALONG THE WAY:
Chamois can sometimes be seen in the scree area in summer.
