From Thyon to Grande Dixence

This first stage of the tour of the Val d'Hérens begins in Thyon, a village located near Sion. The path runs along the Hérémence valley and immediately climbs to the foot of Mont Rouge, near the Essertze gouilles. These peaceful ponds alternate with peat bogs over 13,000 years old, and are an ideal place for a short break.

The path then continues towards the Lac des Dix and the Grande Dixence dam, a building of superlatives. It is the highest gravity dam in the world, the most massive in Europe, and it generates the electrical equivalent of two nuclear power stations!

The path passes close to the lake, then descends to the foot of the dam to complete the stage.
