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.
