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

The Arnaud pass is a cable-equipped passage very exposed to the void. Experience with airy paths recommended. Not recommended for descent. No escape possible.

Very beautiful view when the sky is clear, remember to take a windbreaker at the summit, you will find ibexes. The area is really very simple and does not require strong hiking / trail experience (for the altitude 2930 I think)

In winter as in summer it is perfect, full of spots for bivouacking, a walk or a trail, there are no dangerous areas, and all the passages are simple and well indicated! 👌

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!

Once you start, you can't go back. I only continued at the top because a hiker pulled my backpack up with a rope. I was stuck with my backpack. Or you can pull yourself up 3 meters on the rope, which is a risky task... I couldn't do that. There are many risky, steep sections. Safety would be advisable.
