Extremely difficult
Departure from Sarcenas (Isère)
A challenging hike that allows you to discover the most beautiful (and least known) landscapes around the summit of Chamechaude.
The route includes a few fun climbs and descents, a very short off-trail section, a breach through a cliff, a spectacular couloir and an aerial sangle overlooking numerous chamois, a guaranteed spectacle for anyone aiming to reach the summit before midday.
The route is far from the summer and Sunday crowds.

Difficult
Departure from Sarcenas (Isère)
This circular aims to offer alternatives to the very busy normal route, allowing you to discover lesser-known aspects of Chamechaude, the highest point in the Chartreuse. Without being as technical as the Arnaud breach or as exposed as the Sangle du Jardin, this route is off the beaten track: it therefore sometimes requires a sense of direction and certain (short) steep passages require effort and attention.
Please read the Practical Information section carefully.

In the heart of the Chartreuse mountains, the Col de Porte is a former family ski resort whose ski lifts are now closed. The paths are more or less well marked allowing you to enjoy the trails on cross-country skis or snowshoes. The proposed circuit climbs through forest, coming out on a crest and offers superb views over the entire Chartreuse mountain range.

Departure from Sarcenas (Isère)
This is a magnificent, very accessible winter snowshoe hike, which takes you to the summit of Charmant Som from the Col de Porte resort via the snow-covered D57E road, which is sometimes difficult to see when the snow is deep.
This route offers magnificent panoramic views of all the surrounding mountains with a very reasonable elevation gain. Pass by the Oratoire d'Orgeval and the Chalets du Charmant Som.
