This is definitely the easiest and shortest way to climb the Grand Som.
Caution for those prone to vertigo: between (2) and (3), the walk becomes a climb in places. The passages are often narrow and can be daunting.

This is a loop trail that passes through the Grand Som and, to avoid the crowds, descends along the Arête de la Suiffière (a little exposed but easy), then joins the Col de Freney (and the forest) and, via a path with numerous hairpin bends, returns just above La Correrie, our starting point.

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.
