Mont Granier via the Porte de l'Alpette and the Pas de la Porte

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.
