Description of the route

Follow the paved road from the car park in Thumel and, after a few hundred metres, continue straight along route 12 near a bend on the now dirt track. Cross a bridge and take the path to the left. Cross the Dora di Rhêmes over a bridge and head into 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.
