Departure from Chapareillan (Isère)
A very beautiful loop, much less frequented than the classic Mont Granier route, starting from the beautiful church of Bellecombe and particularly pleasant in summer.
After the Porte de l'Alpette, the hike runs along almost the entire cliff face of the mountain, passing through the magnificent "gardens" of the upper Alpette du Granier and returning to the Pas de la Porte pass overlooking the Grésivaudan valley.

Departure from Crolles (Isère)
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.
