When you get to the main car park in Pila, near the telecabin lift departure point, take the dirt road (14I) that goes under the Pila-Chamolé cables, then takes you comfortable to the Saint-Grat hermitage. Now continue along the private road (19A) until you come to the pasture of Chamolé. Just before the pasture, take route 20A on the left, which goes up the hillside to Col Plan-Fenêtre. Now descent along the route signposted 20, inside the vast valley of Comboé, to reach the pastures of the same name. Go past these until you come to a crossroad, where you ignore branch 14 on the right, and take the left-hand path 16 which goes up to Plan-Valé. Now, continue first across meadows and then over debris until you come to Le Grand Sex. At the crossroad the itinerary bends left, and heads for the crest. Follow this to the summit, which can be recognised by the statue of the Madonna.
Note - this information is not directly connected to the Cammino Balteo path but it is part of the Aosta Valley tourist offer.
