The route runs mainly through the Chartreuse Natural Park, passing through the massif's iconic passes and mountains. The route combines fairly steep climbs, passages through plateaus, mountain pastures and a village.

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.

Footprints in the snow for this walk, which can be enjoyed in the summer sun or in the shade of oak and fir trees...

This is a magnificent, easy walk that takes you through many beautiful natural sites, with breathtaking views of the Grésivaudan valley and the Chartreuse mountains.
