Saint-Rhémy-en-Bosses - Frassati mountain hut

From the village of Saint-Rhémy-en-Bosses cross the road bridge over the Torrent Grand-Saint-Bernard.
About 100 m along the unmettalled road, take the wide footpath to the right which climbs up to the village of Laval.
Then follow the asphalt road through the villages of Couchepache and Mottes and, after a downward stretch, take the unmetalled road which passes under the motorway viaduct and continues on level ground as far as the summer pastures of Devies.
A little further on, take the footpath to the right, alongside a dry-stone wall, then climb up across meadows to the summer pastures of Merdeux Inferiore.
From here there is a short stretch of unmetalled road as far as the summer pastures of Côtes, before the route takes a mid-slope path across to the summer pastures of Moindaz.
It then climbs once again, through wide green meadows, to the summer pastures of Tsa de Merdeux.
After crossing several streams and climbing a steep grass spur, you arrive at the plain of lake Merdeux and at the Frassati mountain hut.
