Between two Alpine capitals there is a massif with a wild character that inspired St Bruno to found the Carthusian order. The proposed itinerary allows you to discover all the faces of the massif: plateaus, cliffs, caves, waterfalls, deep forests, monastic life and views of the largest French glacial lake. The ascent of the most beautiful summits offers exceptional views of the valleys and summits of the other Alpine massifs. However, beware, the silence of the monks must not be disturbed in these mountains... The route crosses the massif from Chambéry to Grenoble without taxi transfers, the opportunity for a soft mobility stay and easily accessible by train!
