September 1, 2025, Col de la Charmette

The approach from the south is very nice, the descent to the north via the forest road is not allowed, but with great caution and pushing in tunnels possible

Highest summer cheese dairy, perched in the middle of the Charmant Som mountain pasture. Well, okay, it's not really the season...

The Col de la Charmette is hidden in the middle of the Chartreuse at the end of a dead-end road at an altitude of 1,261 meters. Located in the middle of the forest, it is a starting point for many hiking trails.

Charmant Som (1867 m) is one of the 3 dominant peaks of St Pierre de Chartreuse, and the most accessible by bike from the Col de Porte. Upstairs you will enjoy a beautiful panorama. The Charmant Som, in addition to being the most easily accessible summit, is the last mountain pasture in Isère that makes and sells its cheese on site. The ascent to the Chalet de Charmant Som from Col-de-Porte is a climb in the Grenoble region. It has a length of 5.5 kilometers and an ascent of 364 vertical meters with a slope of 6.7% on average, which implies a difficulty level of 336. The summit of the ascent is located at 1671 meters above sea level.

The Col de la Charmette (1261 m) is a hidden pass within the Chartreuse Massif. The southern slope – and its three variants – is the official ascent of this pass but it can also be climbed from its northern slope. The latter is closed to traffic but... Despite its modest altitude, it is not easy to climb, you will have to face numerous steps at more than 10%!

Culminating at 1,867 meters, the Charmant Som is an emblematic summit of the Chartreuse massif. From the inn of the same name, accessible by car, the ascent is made without major difficulty. At the top, the panorama is spectacular!

Nestled at an altitude of 1,665 meters at the foot of the summit of the same name, the Auberge du Charmant Som is located on a pretty grassy plateau. Accessible by car, it offers a nice break in a remarkable natural setting. On the menu of its menu, a few traditional dishes that allow you to fill up on energy.
