The appeal of climbing Rachais lies in these ridges. They offer views of the Chartreuse mountains and invite you to venture further into the massif.

Quite a bit of traffic from Corenc, calmer from Clémencières.

Perched at 1,434 meters, the Col du Coq is accessible after a twelve-kilometer climb regardless of the direction of the road taken. It offers a beautiful view of the Dent de Crolles.

A pass with little crowds (end of April 2024). The road is open despite the signs (no snow removal). The bitumen is correct, average in places (mounted in Gravel). A few very steep slopes with a small flat area which allows you to breathe on the Charteuse side. No infrastructure at the top. Road and bitumen in good condition on the St-Pacrasse side.
