Mauvoisin Dam

Located in the Haut Val de Bagnes nature reserve, built between 1951 and 1958, the imposing 250m-high concrete structure is the highest vaulted dam in Europe. To find out more about its history, take Sentier du Barrage. This will lead you to the top of the dam via an ancient 392m long gallery where an exhibition explains how the building was constructed. When you reach the top, you will be greeted by a fantastic view over Mauvoisin Lake with its vertiginous waterfalls.
