An original outing that allows you to discover the superb work carried out here for the construction of the Touvet funicular railway. The ascent is on foot and the descent, to relieve the knees, is by funicular.
(Please note): This route is currently closed. See explanations here
(Comment from a hiker) dated 18 June 2023: small difficult section: crossing the scree slope where you need to use two ropes to reach the path in the forest.

Departure from Pinsot (Isère)
This long route will take you up and down two mountain passes (Morétan and Vay), through the Morétan Lakes valley, and across the wild, unmarked foothills leading to the Col du Vay. You’ll then begin a long, dizzying descent along a balcony path between the Chalet du Vay and l’Aup Bernard, finally arriving – after one last rather steep climb – at a very pretty spot in the middle of which stands the Chalet du Bout, the perfect place to spend the night.
Please note: this hike involves crossing two snowfields as well as a steep, exposed descent.
