Beautiful hike, ideal for families, through alpine pastures and forests from the Lourantze pasture at the end of the sublime Lac de Tseuzier to the Mayens d'Arbaz.

The Bisse de Sion, a typical irrigation canal, was built between 1901 and 1903 by the town of Sion to bring water into the Sionne. 

Today, parts of the bisse are underground and are unfortunately no longer visible. 

The hike starts at the Tseuzier dam and more precisely at the Lourantze mountain pasture, where it crosses the torrent of the same name through wooden gutters. The route continues on the right bank of the lake. To continue the route, you have to follow the access road to the dam and cross the tunnels to reach Les Rousses. The route runs along the open-air bisse to the "Trédouchet" locality, then on the small road built on the canalized bisse. However, the latter is again underground between Trédouchet and Pralan and is therefore no longer visible. It is above Anzère that it is once again in the open air where you can end your hike.

It is also possible to continue the route as far as Les Mayens d'Arbaz, where the finish is near the Étang Long, which is popular with fishermen and has picnic areas with space for barbecues. During the summer months, you can also enjoy a meal on the terrace of the Restaurant du Lac Le Pascali's.

The route of this hike, ideal for families, is gently sloping and offers a truly breathtaking panorama.

At the beginning of this hike, it is possible to combine it with the "Tour du lac de Tseuzier" on the left bank of the lake, starting by crossing the dam wall.

In the Rawyl region, enjoy a meal at the Restaurant du Barrage or at the Étape de Lourantze.
