Bisses are the historic irrigation channels of the Valais. A bisse is an open ditches delivering priceless water from mountain streams – often by daring routes – to arid pastures and fields, vineyards and orchards. Many bisses are still in use today and so are carefully maintained. Numerous trails accompany these historic watercourses, inviting visitors to varied hikes on historic trails.
The Bisse d'Ayent brings water to the meadows and vineyards of Ayent and Grimisuat, either in the traditional manner or by more modern techniques, and it flows into the Revouire Pond. Examples of old building methods have been restored along its course, including corbelled structures in the Lienne valley, girders of the special type known as “boutsets” at Torrent-Croix, and the Follés walkway, built into a ledge at a breathtaking height.
