After a short gondola ride from Haute-Nendaz to Tracouet, take the path along the Lac Noir on the right. The ascent to the Dent de Nendaz is via a mountain path. At 2'461 metres above sea level, next to the cross, enjoy the view over the lake and the surrounding mountains.

Follow the ridge that leads to the Basso d'Alou. Stop for a moment at the top of the Pointe de Balavaux to admire the view of the Cleuson dam and the Val de Nendaz. From there, begin the descent to the Basso d'Alou.

Once at the pass, follow the path back down towards Siviez. You cross the mountain pasture of the same name where the Hérens cows spend their summers.

Once above Siviez, continue along the Bisse de Saxon, the longest in the Valais! It takes you through a superb forest of spruces and larches. In the heart of this forest is the Bourlâ cabin where the guardians of the bisse used to stay. From there, leave the bisse and follow the narrow path back to Haute-Nendaz.
