The Bisses of Nendaz

A bisse is an ancient irrigation channel which can be found in the Valais region of Switzerland. The bisses are an important part of the history of Nendaz.

These irrigation channels are open ditches delivering much needed water from mountain streams to the pasture land, fields, vineyards and orchards of the region. A large number of bisses are still in use today and continue to transport the much need water to the more arid regions.

Run Valais will be taking you on guided runs along the numerous scenic trails that accompany these historic watercourses.

There is a unique network of bisses, with nearly 100km trails running alongside of them, many still have water flowing within their banks. These footpaths can be found at between 700m and 2300m in altitude.
