This road follows the Aravis mountains from the pass above Ugine for more than 20km, through the mountain pastures. It serves as a balcony that overlooks the Val d’Arly with a grandiose panorama over the Alps and the Mont-Blanc.
This route through the mountains is the perfect place to observe the fauna. A large reserve of 3,600 hectares, created in 1968 strivesto protect this environment. Today there are more than 1,000 chamois, 120 mouflons, a large number of roe deer and a few stags in this area.
A protection program also allows a population of Tétras-Lyre (black grouse) to roam in the area. But the local star is of course the marmot who gather in the scree slopes and near the alpine farms.
