Description of the route

From the square in Lillaz, in the municipality of Cogne, take route AV2 which continues into the Urtier valley. After reaching a group of houses and going past a short section of a penstock, it goes up into a wood, and after crossing a number of meadows, reaches the pasture of Goilles Inferiore. Next, the trail goes over the stream, across a small bridge, and continues on the orographic left bank, climbing up inside the wood. You then come to junction where the trees become less dense. Continue along the same itinerary, ignoring the path (13G) to the right that goes into Bardoney valley, until you come to the P.N.G.P. park guard’s lodge. Keep going until you come to another crossroad, where, on the right, the 13D takes you to the Acque Rosse valley. The trail finally takes you to the hill of the same name.
The pass is situated along the Punta Nera - Torre di Lavina ridge and connects Cogne valley with Campiglia Soana. In the past it was used for normal communications between Cogne and Canavese.
