Dams and reservoirs
They are among the biggest, heaviest and most impressive structures in the Alps – the dams and reservoirs situated in the Valais mountains. The biggest of them can be admired during guided tours. Made by human hands, they serve as powerful testimony to the importance of hydraulic energy for a mountain canton’s economy. The Valais reservoirs will continue to play a significant role in the future – as Switzerland’s greatest source of renewable energy. A visit is sure to be an unforgettable experience.
The Mattmark dam, the biggest earthen dam in Europe, lies south of the Saas Valley. The reservoir, used for generating electricity, is a popular destination with visitors interested in learning technical details of its operation and who love its wild, romantic location. Kraftwerke Mattmark AG, which operates the dam’s generators, has built a modern mountain restaurant with an exhibition space here at 2205m. Visitors can enjoy an unimpeded view of the glistening reservoir and a breathtaking panorama extending to the Monte Moro Pass. The crest of the Mattmark dam, at 2200m, is easily accessible by car or public transport. From this point you can take a gentle stroll on a level path around the lake. It takes approximately 2.5 hours to complete the hike around the lake by foot.
