Between trail and off-trail, this hike goes along very beautiful and wide ridges without major difficulties until the passage of the Pissine. During the descent, you will also come across some pretty lakes.
The start of the hike follows the Neuvache with a path that is sometimes paved and therefore picturesque, as the humidity can linger for a while while while the sun has long been on the ridges ahead.
Towards the cross, it is possible to add a return trip to the green lake (about 20 minutes more in return (without stopping). The path climbs up through beautiful twists and turns to the Pas des Griffes.
On arrival at the pass, take and follow the ridges on the left, the ridge is very wide most of the time, no passage requires hands, only two small places require more attention.
The path is obvious until the passage of the Pissine. At this point, on the right is the pointe de la Pissine (seems possible to climb, see Topo JLB). On the left is a small unnamed summit (2724 m) where there is a small casemate.
Descent to the lakes with at times well marked paths, at others less so, but the route is quite obvious. Three beautiful small lakes. For the end of the descent, aim for the path coming from the lake of Curtalès.
Once you have reached the bottom of the Vallon, follow the Terre Rouge refuge, Chapelle Notre-Dame-des-Neiges and the signs for the Chenalette car park.
