Departure from Saint-Pierre-de-Chartreuse (Isère)
A magnificent hike that combines a natural section starting with a climb through the forest, continuing over the pleasant Pas de La Suiffière and then the easy but aerial ascent of the south ridge of the Grand Som, with a cultural section exploring the Monastère de la Grande Chartreuse, a veritable work of architectural art.
