- Don't be surprised: I created the highlight because the previous highlight was in the wrong place (not on the "real pass") -
The Col du Coq is the highest pass in the Chartreuse. From the north / west (St. Pierre) the road is in really bad condition (08/2020), there are some sections for which a gravel bike would be more suitable. Unfortunately, the worst part is also at the steepest (over 15%) point. The ascent from the north / west (I only drove this side) has two longer steep sections, but is otherwise easy to do. You shouldn't be surprised that shortly before the summit it goes downhill for a relatively long time, only to then climb again well. On the east side, you can either descend right into the valley (but be careful: very long, completely unlit tunnel on the descent !!) or to the left to the Petites Roches.

Nice pass with a magnificent view of the Dent de Crolles. Attention very frequented by cars on weekends in good weather ...

quite demanding climb and very damaged road on the Brevardiere side

From the Plateau des Petites Roches, allows a return to Grenoble via the Col de Porte.

Add approx. 500m vertical drop, but much prettier than Grésivaudan.

Exceptional site at the foot of the Dent de Crolle with access via a wild forest road

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.

Very nice climb from the Isère valley to be driven. On the other hand, however, there is a steep and dangerous road.
