Very simple climb, pay attention to the asphalt which is very slippery and easy to slip.

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 Chanteloube viaduct, located in the town of Chorges, emerges like a silent vestige of a bygone era. Started in the early 1900s, it was initially intended to connect Chorges to Barcelonnette by rail. The project was finally abandoned in the 1930s. Each year, in the spring, as the lake swells from melting snow and seasonal rains, the viaduct disappears beneath the waters. However, in winter, when the lake level drops, the viaduct emerges from its aquatic lethargy, revealing its majestic arches and solid pillars.

The desire to establish a dam to tame the tumultuous waters of the Durance dates back to the 19th century. The creation of the lake marked the beginning of significant economic and tourism growth for the region. The site has quickly become an essential tourism destination in the Southern Alps. This work therefore makes Serre-Ponçon one of the largest artificial lakes in France and one of the largest earthen dams in Europe.

Constructed over six years and completed in 1961, the barrage flooded two villages - Savines and Ubaye. Climbing up past the barrage, you can see just how it as built to almost blend into its surroundings.
