The Dent de Crolles, at 2,062 meters, is one of the best-known peaks in the Chartreuse. This distinctive limestone mountain towers high above the surrounding area and offers, on a clear day, a magnificent view over the Alps and the Grenoble valley. The hike there leads through varied mountain meadows, rocky terrain, and impressive limestone landscapes. A strenuous climb, but the views and the special atmosphere of the Chartreuse make it absolutely worthwhile.

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.

nice climb up to the intersection...then the road going to the fort is cleaner depending on the day (twigs, bread needles...)
