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.
Grand Bisse de Vex
It is popular with summer visitors who like to follow its gentle course, especially the section between the resort of Veysonnaz and les Mayens-de-Sion. Even during heat waves, the air here is pleasantly cool thanks to the shelter provided by the trees. The forest consists of conifers, mainly larches, whose fallen needles form a thick and soft carpet on the trails.
