Coordinates: 44.471358 N, 6.271042 E | Height: 124 m | Type: Dam
If you’re wandering the sun‑kissed valleys of Provence‑Alpes‑Côte d’Azur and crave a blend of engineering marvel, turquoise water, and rugged mountain scenery, the Barrage de Serre‑Ponçon should be at the top of your itinerary. This 124‑metre‑high concrete dam, perched above the shimmering Lac de Serre‑Ponçon, is not only a feat of French engineering but also a gateway to outdoor adventure, photography, and tranquil moments on the water’s edge.
About Barrage de Serre‑Ponçon
Built in the 1950s to tame the Durance River and generate hydro‑electric power, the Barrage de Serre‑Ponçon (often simply called the Serre‑Ponçon Dam) quickly became a symbol of post‑war modernization in France. Its massive concrete wall stretches across the valley near the village of Chorges, creating one of the largest artificial lakes in Western Europe—Lac de Serre‑Ponçon.
The dam’s 124 m height and 600 m length hold back roughly 1.3 billion cubic metres of water, providing flood control, irrigation for the surrounding agricultural plains, and a reliable source of renewable energy. The reservoir’s turquoise surface reflects the surrounding peaks of the Alpes de Haute‑Provence, making it a favorite spot for photographers and nature lovers alike.
Beyond its functional role, the Barrage de Serre‑Ponçon has become a cultural landmark. Its sleek, mid‑century design blends harmoniously with the rugged landscape, and the site offers panoramic viewpoints, interpretive panels, and occasional guided tours that explain the dam’s construction, its environmental impact, and its role in the regional economy.

How to Get There
By Car
The most convenient way to reach the dam is by car. From Avignon (≈ 90 km), follow the A51 motorway north toward Gap, then take the D944 exit for Chorges. The drive is scenic, winding through pine forests and alpine pastures. Parking is available near the main viewpoint and the visitor information kiosk.
By Train & Bus
If you prefer public transport, take a TER train from Avignon or Marseille to Gap (the regional hub). From Gap, regional bus line L‑05 runs to Chorges and stops within a short walk of the dam. Check the latest schedules on the SNCF website, as services are less frequent on weekends.
By Bike or Hike
For the adventurous, the Véloroute du Lac de Serre‑Ponçon offers a well‑marked cycling route that loops around the lake, passing the dam at several scenic spots. Experienced hikers can also follow the GR 56 trail, which skirts the reservoir and provides stunning viewpoints of the structure.
Tip: Bring a printed map or download offline maps (e.g., MAPS.ME) because cellular coverage can be spotty in the higher valleys.
