Europe's largest earth dam, the Mattmark Dam, is located to the south of the Saas Valley. The reservoir, which is used to generate electricity, is a real powerhouse and fascinates visitors not only with its technical details, but also with its wild and romantic location and is the starting point for numerous impressive hikes.

The Mattmark Dam, located in the Saas Valley, is an important structure and at the same time a place of historical and emotional significance. It was built between 1960 and 1967 and, with a height of 120 metres and a volume of 10.5 million cubic metres, is the largest earth dam in Europe. The dam was created by backfilling moraine material and is mainly used to generate electricity, producing around 680 million kWh annually. A tragic natural disaster occurred in 1965 when an ice avalanche from the Allalin Glacier buried 88 workers. Today, the Mattmark dam is a popular excursion destination for hiking and mountain biking, as well as an important part of flood protection in the Upper Valais. A restaurant and an exhibition room on the top of the dam offer visitors an insight into the history and function of the dam.

The road to the Mattmark dam is closed in winter.
