The Chanteloube viaduct, located on the Serre-Ponçon lake, is an unusual place. Built for a railway line that was never completed, this partially submerged viaduct offers a fascinating spectacle, with its arches reflected in the turquoise waters of the lake.

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.

Mount Colombis (1733 m) is one of the least known monsters of the Alps. Very tough climbs like Mont Ventoux, Grand Colombier or Mont du Chat have a much greater reputation in the cycling world. But it's not just because of that... to put it bluntly, it's because it's so scary!

For climbers and panorama fans. I don't want to judge whether it is THE most beautiful view of the Lac, because the view from the Pic de Morgon is not to be despised either, but you can't get up there by bike. The effort of climbing up the Mont Colombis with 2-digit percentage values is definitely worth it and is also rewarded with a spectacular panorama.
