Grande Dixence – the 285 Meter High Dam

Val des Dix

The Grande Dixence, the world's highest gravity dam, collects the meltwater of 35 Valaisian glaciers in the region surrounding Zermatt and leading up to Val d’Hérens. The dam can be viewed, and is the starting point for several hiking tours.

The first dam was built in Val des Dix as early as 1934. Grande Dixence, built in the years from 1951 to 1965, is a construction of incredible magnitude. It is 200 meters thick at the base, 695 meters long and 285 meters high. Six million cubic meters of concrete were required for the construction of the dam. The large reservoir holds 400 million cubic meters of water, which is channeled into the lake through 100 kilometers of tunnels.

Guided tours with slide shows and films take place in the interior of the dam. An aerial cable car takes visitors to the top of the dam, which has a magnificent panoramic view of the Valaisian mountains. A variety of mountain hikes begin here, such as the high altitude Ibex Trail , which was established by the Grande Dixence S.A. in collaboration with Pro Natura Valais.

    If you like your scenery big, then do not miss a trip to see the dam! Both the dam and the surrounding 10,000ft peaks will astound you in their magnitude. The photos shown above do not do justice to the scale of the place. The dam itself is massive and it's at least 300ft from the top of the dam down to the lake. We thought that this would be just another day out in Switzerland, but it turned out to be one of the highlights of our whole trip to the country. Afterwards follow the signs to the picture postcard village of Evolene, not far away.
