Two passes in one ascent: Romeyère and Mont Noir, the highest point in the vast Coulmes beech forest and also the highest road pass in the Vercors. The scenery is varied and always interesting: starting in Pont-en-Royans with its troglodyte houses, you first climb the spectacular gorges de la Bourne (a route that can be vertiginous and very busy with cars), then up the tranquil countryside of Rencurel to the Col de Romeyère, before finishing on the steep forest road, often in poor condition... read more

Two passes in one ascent: Romeyère and Mont Noir, the highest point in the vast Coulmes beech forest and also the highest road pass in the Vercors.

The scenery is varied and always interesting: starting in Pont-en-Royans with its troglodyte houses, you first climb the spectacular gorges de la Bourne (a route that can be vertiginous and very busy with cars), then up the tranquil countryside of Rencurel to the Col de Romeyère, before finishing on the steep forest road, often in poor condition, that leads to the Col du Mont Noir. All in all, a great cycling experience.

From the Col du Mont Noir, we recommend descending to Cognin via Malleval, to admire the breathtaking Gorges du Nan.

Deux cols en une montée : Romeyère et le Mont Noir, le point culminant de l'immense hêtraie des Coulmes et aussi le plus haut col routier du Vercors.

Le décor est très varié et toujours intéressant : partant de Pont-en-Royans et ses maisons troglodytes, on grimpe d'abord les spectaculaires gorges de la Bourne (route parfois vertigineuses et qui peuvent être très fréquentée par les voitures), puis on remonte le champêtre et tranquilleval de Rencurel jusqu'au col de Romeyère, pour finir par la route forestière pentue, souvent en mauvais état, qui aboutit au col du Mont Noir. En bref, une très belle expérience cycliste.

Du col du Mont Noir, il est conseillé de descendre sur Cognin en passant par Malleval, pour pouvoir admirer les très vertigineuses gorges du Nan. On peut également redescendre sur Pont-en-Royans mais en passant par Presles et les falaises éponymes, qui présentent elles aussi un cadre vertigineux et spectaculaire, étonnamment méridional.

This climb takes you to increasingly quiet areas on beautiful roads. So there is a lot of traffic at first, but you are not very bothered by it. The road winds very nicely through the mountains.

Deze klim brengt je naar steeds rustiger gebied over prachtige wegen. In het begin is er dus wel veel verkeer, maar daar heb je niet heel veel last van. De weg slingert heel mooi door de bergen.
