This itinerary is a section of Alta Via 1, AV1. From the village of Saint-Rhémy, cross the Grand-Saint-Bernard stream and 100 m after crossing the dirt road, take the wide path on the right that goes up to the residential area of Laval. Follow the paved road through Couchepache and Mottes then, after a brief section in descent, take the dirt road on the right, which goes under the motorway overpass and continue on level ground to the pasture Devies.
Just after this point, take the path on the right that runs along the dry-stone wall, which goes up through the meadows until it comes to the pasture of Merdeux Inferiore. From here, a short section on the dirt road takes you to the pasture of Côtes, then continues on the path, which runs up the hillside towards the pasture of Moindaz. Go up the wide green meadows until you you come to the pasture of Tsa de Merdeux and then, after crossing several streams, and going up a steep grassy crag, you come to the plateau of Lake Merdeux. From here, the trail rises in altitude and lead to a debris basin surrounded by a beautiful, jagged, rocky crest. Cross the basin and take a diagonal slant to the left, and after a few narrow bends you come to the final steep debris slope that leads up to Col de Malatrà.
