Dent de Crolles

Highlight • Summit

At the top of the Dent de Crolles (2,062 meters), the view emerges over the entire Grésivaudan valley. Second highest summit of the Chartreuse massif after Chamechaude at 2082 meters, its ascent is however more technical.

Clémencières Pass

Highlight • Mountain Pass

A wonderful little pass just outside Grenoble. The climb via the Narbonne road is definitely worth the detour. It's steeper than the traditional route, but so peaceful!

first difficulty of the Col de Porte. At the summit, we enjoy a fairly short descent before resuming the ascent of the Col de Porte

A stunning summit with views of Mont Blanc. The two climbs from the Col des Ayes are relatively steep, but steel cables are installed at the more dangerous sections. The climb north via the Trou du Glaz is a bit longer and a bit easier. The climb east is a bit steeper and more exposed. The view is good, though.

Culminating at 2,082 meters above sea level, Chamechaude is the highest point of the Chartreuse massif. Easily accessible from the Col de Porte, it offers an exceptional 360-degree view. You can see a beautiful part of the massif as well as those in the surrounding area. On a clear day, the view extends to the highest Alpine peaks.
