From Erésaz, a hamlet in the municipality of Emarèse, take trail no. 1 near the church, which goes up to meet the regional road. Cross this, then continue towards the right on the mule track which, after crossing the paved road twice, takes you to Chassan. Here the trail goes along the internal road network towards the village then returns to the mule track at the top of the residential area. The itinerary rises steeply close to a canal, where the trail continues in a straight line. After going up a slope scattered with larch trees, you come to Sommarése. Now, go along the regional road for about 100m on the right, then, near the municipal car park, take a small road on the left signposted 5. After reaching the chapel, take the mule track on the right, which after a short while meets the private road from Col de Joux and later becomes a dirt road near a cabin. Continue along this road until you go past a meadow and, after leaving the cart track leading to an irrigated basin, continue straight ahead along the path that goes into the wood, crosses a dirt road, is joined by trail no. 1B from Col du Joux and leads to the crest, taking you to Testa di Comagna.
Note - this information is not directly connected to the Cammino Balteo path but it is part of the Aosta Valley tourist offer.
