The Truyère river starts in the Monts de la Margeride, at the peak of the Three Sisters in Lozère, at 1470m altitude; it slowly winds around the old massifs, then reaches a point where it was diverted by the lava flows from the Cantal volcanoes.
Continuing for 170km, the Truyère has carved through granite mountains and formed many deep gorges.
“The Truyère gorges, initially the ‘well-behaved’ tributary of the Lot, begins in Margeride, discreetly winding through granite-covered hills and marshland; later it cuts into the land forming steep, rugged gorges. Its flow, by this point considerably powerful, has seen a series of huge hydroelectric dams built.
The valley hesitates between Cantal (Saint Flour, Carladez) to the north and Aveyron (Viadène, north Aubrac) to the south, then joins up with Entraygues and Le Lot.”

Visits on the Route de l’énergie
A wonderful map to explore the Barrages
At the source of the Truyère, around Sarrans Lake, at the confluence, towards the Lot valley
All the info you need is on this map. Great to plan out a holiday taking in all of the magnificent valleys between Aveyron and Cantal…

The Truyère EDF Centre in Couesques
Starting in the old control room of the Couesques plant, a new, fun, interactive museum has been built to teach you all about hydroelectricity.
This new 600m2 museum tells the history of hydroelectricity in the Lot and Truyère valleys, with an educational timeline containing models, touchscreens, films, experiments and more, explaining how the plants and dams produce the number 1 renewable energy.

Visit the Montézic Hydroelectric Plant
The Montézic Hydroelectric Plant, located 400 metres underground, is the second most powerful plant in France, producing 920 megawatts. It uses cutting edge technology to transfer energy via a system of pumps, allowing it to produce hydroelectricity in under two minutes.
The plant began operating in 1982, and is the youngest part of the Lot-Truyère hydroelectric chain. It is currently being renovated.
Every sunday, EDF opens the plant’s doors to the public and gives fantastic guided tours, beginning with a presentation of how the plant works and its place in the Truyère hydroelectric chain, of EDF’s workers and their different tasks, then of the history of the site and its construction. It ends with an impressive look at the plant’s machine room, where the 310 lightbulbs on the ceiling have been replaced with LEDs to improve the room’s lighting.
This year, EDF has also purchased two seven-seater electric vehicles to safely transport visitors around the site.
