A long and beautiful cross-country itinerary. Never forget that these fabulous trails are in mountain terrain and require technique on both the uphill and downhill sections.

Carte & Points d’intérêt

J'y vais


The first ascent takes you to the Arponts plateau, partly via a lovely forest track, then onto a magnificent singletrack balcony leading across the mountainside to the Plan Sec Refuge located above the lakes of Plan d'Aval and Plan d'Amont.
The descent from Plan d'Aval is on the Moulinator 1 & 2 enduro trails (back with a vengeance!).
This challenging itinerary requires good physical fitness and a little technique. Exceptional views over the mountains and valley and the guarantee of a high-mountain decor.
Located on the edge of the Vanoise National Park, the Plan d'Amont and Plan d'Aval dams (built between 1945 and 1956) contribute to feeding the power stations in the valley. Both lakes supply water to Mont-Cenis lake, despite the latter being located on the other side of the valley.

Departs from: Plan de la Croix (on the road between Aussois and Val Cenis Sardières).

From 01/05 to 15/10.
