Departing from Aproz, set off towards the village of Fey before joining, after a fairly steep passage, the main road Sion-Nendaz at Basse-Nendaz. The itinerary then branches off to the left on to a quieter road leading to Saclentse.

Then when you reach the main road towards Siviez turn right towards Haute-Nendaz and cross the heart of the resort before plunging towards Isérables on a windy road overlooking the valley. A sharp left turn takes you across a wooden bridge leading you along an unpaved track towards La Tzoumaz.

As you leave the village, the road winds up through the forest, then through the mountain pastures until you reach the pass located at 2’173 metres above sea level. The last part runs along a gravel hard pack track.
