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.

The Col de la Gardette (2125m). A tough and beautiful climb from Chorges towards a bucolic pass where green mountain pastures stretch as far as the eye can see. Flowering mountain pastures are visible along the climb, while Lake Serre-Ponçon stretches along the mountainsides. At the top, the Réallon valley is also revealed when the sun shines on it.
