Connecting the Gapençais and the Durance valley, the Lebraut pass is a magnificent viewpoint over the Serre-Ponçon lake. Small roads that are as discreet as they are panoramic provide access to the heart of resplendent nature.

As stated by others and nice climb, very quiet. But man-man-man what a bad road surface on the east side.
