Description of the route

Park the car in Gimillan, in the municipality of Cogne. Take route no. 8 on the right of the village, which leads to the Alpine pastures in the Grauson valley. Continue amid the high altitude pastures until you come to Alpine pastureland of Pila, Crouzet and Grauson Désot. At a junction that you meet soon after this last place, take route no. 8A to the left which climbs up to the Alpine pastures of Grauson Dessus, passing a junction along the way where the right-hand path, which you ignore, would take you to Lake Coronas. Continuing on along the same route, you come to a high plateau where the first of the Lussert Lakes is located.
To reach the other three lakes, continue climbing past a series of steep rocky crags, which bring you to the hollows where the lakes are situated.
