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.

From this cross there is a splendid view of the Chartreuse massif, the Grésivaudan valley towards Grenoble and Chambéry, the Belledonne massif and, as an added bonus, there are orientation tables. Super 👌!

Magnificent lake! Accessible to all! As a bonus, you'll find ibexes and a few marmots if you're lucky. For the more courageous, you can climb to an altitude of 2,900 m by continuing on the path with a magnificent view if the sky is clear!

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.

Starting point for the Dent de Crolles for the bravest and for Pravouta for those who wish to take a short family stroll.

Magnificent and relatively easy pass, with basic fitness. Offers a magnificent view of Mont Blanc. Be careful though, the Chaos and the Col are currently completely covered in snow. Being in a group, I did not attempt the ascent of the Col which, without equipment, can be particularly slippery and dangerous. Possibility of going back down via Prayet towards Saint Pierre en Chartreuse. Tested in November, however, no problems observed, very accessible.
