The route starts in Aproz and climbs to Siviez car park near Cleuson dam, offering a magnificent view of Mont Fort and Mont Gelé.
Starting in Aproz, the route first heads towards the village of Fey. Your efforts begin in earnest once you leave the village, with a short but relatively steep climb to the main road passing through the village of Basse-Nendaz, where you turn onto the little-used Saclentse road. Up until this point, the route is identical to the one leading to the Col de la Croix-de-Cœur. As soon as you reach the Route de Siviez, high above Nendaz near Bleusy, you can enjoy a breathtaking view of Mont Fort and Mont Gelée at the far end of the Val de Nendaz. Continue in the direction of Siviez on a steady slope, with the wall of the imposing Cleuson dam gradually coming into view before you reach your destination near the ski lifts of the 4 Vallées ski area.
Cyclists with a head for heights can reach the top of the dam via a 3.5km road, much of which is surfaced with gravel. Follow the MTB signage.

From Aproz, follow the road that leads to the village of Fey and continue until you reach Basse-Nendaz, where the route forks to the right. Follow this path for 1.7 kilometres before turning left and continuing on a narrow road that follows a little-used stretch of route via Saclentse. Up until this point, the route is identical to the one leading to the Col de la Croix-de-Cœur. Turn left and continue for a little over five kilometres along the Route de Siviez until you reach the foot of the ski lifts. There is a finishing post at the edge of the big car park where you can take a photo to immortalise your climb.
