The Charmant Som is also the most easily accessible peak (see alternative) and the last Alpine pasture in Isère that still producces and sells its cheese on site. From the lodge car park, take the 'Grande Randonnée' path (French Hiking Route) through the pasture. Before you reach the other slope, turn left onto the ridge until you reach the summit cross (follow the paths made by previous hikers).
The descent follows the same route in reverse.
