Randonnée pédestre

Émosson - Grenairon

Finhaut

Stage 1 of the Tour du Ruan

From the Col de la Gueulaz, Emosson (1965 m) coord. 561.170/101.980 to the Refuge du Grenairon or Chalet-Hôtel du Buet (1974 m) coord. 550.420/98.050.

This 7-hour stage passes along the Emosson lake to climb towards the Vieux-Emosson dam (2206 m) and bypass it on the right bank to reach the site of the dinosaur tracks (2400 m).


Then take the path that leads to the Col du Vieux (2572 m) and continues in a steady climb to the highest point of the Tour: the Cheval-Blanc (2830 m). A magnificent panorama from which you can see the Bernese Alps, the Rhone Plain, the Valais Alps, the Mont-Blanc massif, the Chablais and the Jura all at once. From here, a slight descent towards the Lac de plan du Buet through the Combe of the same name. This part of the route is certainly the most challenging part of the Tour in case of bad weather, especially in fog (lack of markings).

From the lake, the path leaves in the direction of the Frètes du Grenier, passing the Grenier de Commune (2775 m) and the Cathedral (2498 m), to continue in a labyrinth of large limestone blocks entangled like castles. On our left, the immense and wild west face of Mont-Buet. On the descent, at an altitude of 1974 m, we find the Grenairon refuge where the first day of the Tour ends.
