Description of the route

Leave the car in Valnontey, in the municipality of Cogne, and cross the bridge over the stream and climb up the vast plateau, where the Paradisia botanical gardens are situated. On the left, take the path for the Sella refuge which, after a short flat section, goes into the conifer woods and winds gently upwards. Crossing the stream over to the left takes you to vast pastures which rise then descend again gently, to cross back over the stream. The trail now goes up in long diagonal tracks to reach the basin where the Sella refuge stands along with the park guard’s lodge. From here the trail crosses the flat meadows, then climbs softly in a long diagonal line, until it runs alongside the stream. When you get to a steep slope, the trail heads left, crosses a grassy bank and starts to wind up along a wide stony slope. After crossing the rocky wall, you come to Col Loson.
