Description of the route

From Vieux Crest mountain hut, take first the track and then follow the unmetalled road leading to the rural hamlet of Sousun.
Passing through it, the route heads out over level ground to Charcherioz.
Continuing on from here for a short while, on the unmetalled road and then along the track, the route climbs up to the G.B. Ferraro and Guide di Frachey mountain huts.
The path now descends towards the valley, through the summer pasture of Raccard to the village of Saint-Jacques.
Crossing the road bridge over Torrent Evançon, the route turns right along the path which climbs up through meadows and sparse woods.
Just after the summer pastures of Croues you reach an unmetalled road which the path crosses at various points, until it reaches the summer pasture of Nannaz inferiore.
The route now continues entirely on unmetalled road, which climbs up as far as Grand Tournalin mountain hut.
