The Visperi irrigation channel, which carries water from the Nanztal valley, is partly carved into vertical rock. Beautiful views and vistas of the Lötschberg south ramp opposite accompany the entire hike.

Starting in Gamsen village, signposts lead you into the forest towards Eyholz. From here, the hike follows the spectacular Visperi irrigation channel. Some sections of the terrain are rocky and steep, but most of these passages are secured with handrails – however, sure-footedness and a head for heights are essential for this hike. Towards the end of the hike, you will reach the Schlegel, which – driven by a water wheel – provided the Vispern with information about the flow of water through its knocking sounds. Through the chestnut forest and lush meadows, you will reach the town of Visp.

“Suonen” is the name given to the historic irrigation channels in Valais, most of which are still preserved or even in operation today. They were used by farmers to channel precious water from mountain streams to orchards, pastures, and vineyards on the mountain slopes to protect them from drought. The Visperi draws its water from the Gamsa in the Nanztal valley, then crosses forests, fields, and steep rocky passages, finally ending above Visp.
