Caution! There is a particularly tricky section between La Chandelle and Lac Rouge due to the trail having collapsed.
From Névache, take the D301T towards the Upper Valley and park at the end of the road at the Laval car park (2030m).
(S/E) From the car park, go to the roundabout and take the path to the north-north-west, then turn left at the first intersection.
(1) Cross the Clarée on the Pont du Moutet bridge.
(2) After about 100 metres, at the intersection, take the path that climbs up the hillside on your left. This path climbs steeply through the pastures towards the west.
(3) Just before crossing the Rau des Moutet, you will reach a crossroads. Ignore the path on the left, which is the return route, cross the stream and continue climbing to reach Lac des Béraudes (2,504 m).
(4) Descend to the left, east-southeast, behind the yellow sign for Lac des Béraudes, to take the balcony trail. This trail crosses the scree slope to the southeast and then south under the Roche des Béraudes and the Chandelle du Lac Rouge. After a passage of large boulders where you have to navigate from cairn to cairn, you will come across a good trail.
(5) Take this path to the right, heading west-southwest. It climbs steeply up a scree slope to reach the Lac Rouge dam at the foot of the rock face of the same name.
(6) Descend a few metres to reach the lake, which you can go around on the right.
To return, descend via the same path to the boulder field.
(5) Do not attempt to cross the boulders again, but continue your descent to the right on the path.
This descends into the north-east and then north pastures and joins a crossroads marked by two cairns.
(7) Turn 90° to the right, take the path to the east and you will soon rejoin the path you took on the way up.
(3) Descend to the right along the same path to the Laval car park (S/E).
