A spectacular section of the route that captures the essence of the Drôme Valley. On one side the crystal-clear, swimmable waters of one of Europe's last natural rivers, on the other the unmistakable profile of the Forêt de Saoû and its three iconic peaks (the Trois Becs).

Splendid panoramic viewpoint immersed in nature, ideal for a short stop during the route. From here, a wide and evocative view opens up over the surrounding landscape, with valleys, mountains, and small villages that follow one another on the horizon. A perfect place to stop, take some photos, and enjoy the tranquility and beauty of the panorama for a few minutes.

The climb starts quite gently from Chamaloc and becomes progressively more challenging as you enter the spectacular valley. The most scenic part is the final section, with hairpin bends set into the rock faces and the impressive crossing of the Col du Rousset tunnel.
