Roc Cornafion, Mountain summit in Isère, France

Roc Cornafion is a mountain summit in the Isère region that rises to 2049 meters and forms part of the eastern boundary of the Vercors massif. The peak features rocky ridges and steep slopes that give way to forested lower elevations typical of this Alpine landscape.

The mountain has been crossed by shepherds and travelers for centuries using pathways that connected Alpine valleys. These traditional routes continue to serve as the basis for modern climbing approaches to the summit.

The plateau of Cornafion, between roughly 1,600 and 1,900 metres, is a paragliding take-off site used mainly in north-west, west, south and south-west winds. Pilots fly over the Villard-de-Lans valley and can work the ridges north and south of the summit; south-west winds allow soaring above the combe de Pissavache. Landing options include Les Espinasses, five minutes from the car park.

The climb is best attempted during warmer months when snow and ice clear from the routes. Visitors should bring proper mountain boots, water, and weather protection, as conditions can change rapidly at elevation.

The Cornafion plateau between roughly 1,600 and 1,900 metres is walkable without special equipment, while the summit itself is harder. Its rock faces hold climbing routes graded from 3a to 7a, including the 283-metre Arête S and the 200-metre Persévérance at 7b.
