Description of the route

From the car park in Thumel, follow the path no. 11B which, after crossing the Dora di Rhêmes on a bridge, follows it for a few hundred metres before entering the valley of the Grand Vaudalaz stream. After a steep climb, you come to a plateau with Alpe Grand-Vaudalaz. Now, as you come to a junction, continue along route 13A on the left. You first go up onto high altitude meadows and then deposits of debris and moraine to reach Col Rosset.

With respect to the downloadable gpx and kml tracks, you need to pay attention to the trail variant (see attachment).
