Park near the bridge over the Cristillan at or below Les Chalmettes.
(S/E) Cross the bridge and start climbing through the forest, following the path. At thefirst junction, leave the signposted path towards Les Chalmettes on your left. Continue along the path on the right, climbing via wide switchbacks to reach the clearing at the Ravin de Beaubarnon.
(1) Walk up this meadow, keeping to the left, and look out for a cairn further on, just before the rocks.
(2) Head straight up to the left onto a path that goes round these rocks and continues up a fairly steep climb along a narrow track, heading towards a large, menhir-shaped rock. You’ll reach a flat area and then the Col de Beaubarnon.
(3) Follow the path downwards until you can see the Col Albert path.
(4) Take this path to the left and reach the foot of the pass. Here, take a wide hairpin bend to reach the Col Albert.
(5) Carefully follow the ridge to the left to reach the highest point of the walk at the Tête de Rissaace or the Longet.
(6) Begin the descent, taking care, to reach the Col de Clausis.
(7) Turn left and follow the yellow-marked path across the large Clausis valley to reach Lac de Clausis.
(8) Continue the descent, entering the forest to quickly reach the Étable des Génisses, also known as the Cabane de la Lavine.
(9) Take the wide track and continue down the gentle slope, crossing the Cristillan at the ford. A few hundred metres further on, you’ll reach the Claux car park.
