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.

A beautiful path apart from the ford which must be crossed using a rope There is a path that goes down further which allows you to avoid this passage.

is it really worth the name "must-see"... given that the useful must-see is 5 minutes away (Col de l'Emeindras).... in my opinion, too many must-sees risk making you less You can spot the real must-haves, right? Good walks to all

Nice little descent to learn how to position the front wheel correctly, while being careful on certain sections to ensure that the child does not pick up too much speed or panic (risk of falling on the left of around 3m at certain locations).
