The ascent to the Tseuzier dam, which rises to an altitude of 1777 metres, begins in Sion and is almost 25 kilometers long. From the vineyards of the central Valais to the Lac du Tseuzier, this route offers breathtaking panoramic views at every turn. All along the way, the route is signposted. 

The first few kilometers wind through vineyards to reach the combe de Voos, gradually rising above the plain to the village of Botyre. The road then climbs up the Liène on a sometimes steep slope through the forest, allowing you to admire the view of the highest peaks above the opposite side of the Rhône valley. The climb continues with a few hairpin bends up to Lac du Tseuzier, in which the surrounding peaks are reflected.
