This hike starts at a bend in the road leading up to the Col de Colombière, where there is a small car park with space for a few cars.
(S/E) Then climb up the small path. This small path climbs up a corridor and becomes increasingly steep, crossing a few small scree slopes and rocky outcrops. You will arrive at the Col du Rasoir between Pic du Jalouvre and Pointe Blanche. As its name suggests, this pass is as sharp as a razor blade...
(1) The descent opposite is just as steep and takes you down a scree slope. At the start of the season, there may still be snow, in which case you can descend by scrambling.
(2) Pass under the Dents du Jalouvre and turn left to reach the Col de Sosay.
(3) From the pass, you will see Lake Lessy with houses around it. Descend in this direction on the trail.
(4) Pass the Chalets de Lessy and go around the lake on the right, leaving it on your left, and climb towards the Col de la Forclaz, always taking the path on the left without descending.
(5) Once at the pass, turn left onto a small, gently sloping path that will take you across a scree slope and the side of the Aiguille Verte. You can still admire Lake Lessy. When you reach the path that goes around the lake on the other side, the path climbs to the right to cross the ridge at Co.
(6). The descent is quite steep through the mountain pasture. Keep following the path that turns to your left to reach the foot of a Via Ferrata.
(7) Continue on and, after a long traverse under a large rock bar on the side of the Pic du Jalouvre, you will return to the car park (S/E).
