From Etirol (1598 m) take the dirt road (n. 107 / 7) that goes into the valley upwards, walk by the summer pastures Tsantsevella and go on to the little lake (n.105), cross the torrent and continue along another dirt road (n.1) as far as the Beutsòlo pastures. Follow the private road (no.1), and leave it on the left to take the path that leads to the ruins of Hospice de Chavacour. At the crossroad near the ruins, take itinerary 5 on the right, which soon leads you to Alpe Château. Cross this road and continue along itinerary 5 until you come back to the dirt road. After a few metres you come to a crossroad, where you take the left-hand branch, which follows the trail (still no. 5) and reaches Alpe Grand-Drayères, visible from afar, owing to its characteristic vault shape, then goes on to the Rivolta bivouac.
The last section of the trail is very demanding.
Note - this information is not directly connected to the Cammino Balteo path but it is part of the Aosta Valley tourist offer.
