It is indeed Chartreuse. There is also a "must-see" that presents "a magnificent view" of Chartreuse when it is actually Belledonne!!

Very pretty, but it's not the Vercors, it's the Chartreuse, Mont St Eynard to be exact.

Gravel section with 40mm tires. (Caracal Hutchinson) In a very dry period (end of June), nothing to complain about in the St Hilaire/Col de Marcieu direction.

Conditionally recommended: Definitely recommended on a mountain bike. Relatively bumpy on a gravel bike. But doable with 45-inch tires and 2.5 bar pressure. There are few views along the trail, however, as it leads through dense forest.

Beautiful pass. Relatively steep climbs from the valley. There are rest stops at the top.
