Col de Romeyère, via the Écouges road

Highlight (Segment) • Other

Typical of the Vercors region, the Écouges road winds its way through the cliffs to reach the Col de Romeyère, at 1,074 meters.

In summer, the cool air is welcome as you cross the Drevenne (canyoning) and enter the forest.

Col de Romeyère

Highlight • Mountain Pass

An iconic pass in the Coulmes massif, accessible after a difficult climb on the north side, and an easier one on the south. It provides access to the Col du Mont Noir, the massif's benchmark pass.

Located in the Coulmes Forest, with no view or panorama, the Mont Noir Pass peaks at an altitude of 1,421 meters.

Little known and far from traffic, it nevertheless offers five very different climbs:

The climb up here is one of the most beautiful in the Vercors.
Continue to the Col de Prélétang!
