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. A modern mountain restaurant with an exhibition space is located 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.
The restaurant in Mattmark is closed from 19th October 2020 until spring 2021.
