A beautiful pass, with beautiful landscapes. It's a must to do in the summer when the road is closed to cars, so you can really enjoy this climb 😉

One of the most beautiful views of the valley, with a rather unusual view overlooking the mole. It is then possible to cross the ridges to Pointe du Haut Fleury but be careful at Pas de l'Ane which is quite exposed despite the handrail. Strictly not recommended in case of dizziness.
