Departure: at the end of the Malpasset road (D 37), staying on the right-hand side of the motorway. (Parking is available without going to the dam car park on the left).
(S/E) Pass the ONF barrier, cross the first ford, turn immediately right with your back to the motorway, and cross a second ford.

Continue along this route. You will reach the top of the climb at Marre Trache.
(2), take the only fork to the right on this section, towards Lac de l'Avellan. Descend towards the lake. Here you can take a break in a pleasant spot.
To continue the hike, walk along the lake shore on the right. Continue towards the nearby car park.
