Description of the route
From Planaval, in the municipality of Arvier, follow the paved road towards La Clusaz and, after the village, continue to the left, then take the bend after which you come to the start of the trail (at the start of the road). This goes up through a thick wood, initially of broad-leaved trees then conifers, and comes into contact with the ruins of the Bénévy pasture, and ends at the meadows near an aqueduct basin. Go further up to reach a plateau scattered with large rocks. Now continue along the path surrounded by green meadows, then follow the section that runs alongside the stream and crosses over it to the left. The trail then climbs a ridge that leads to another plateau. Go back over the stream towards the right, then continue along a flat section until you come to the remains of Baraques du Fond pasture. Just after the pasture, the trail turns right and goes up to Lake du Fond where, after crossing the brook, it starts to flank a short section of the bank, until it returns to the path on the right that climbs up again amidst the meadows. Go up a number of grassy crags, then take a long right diagonal bend along the hillside, until you come to the final rocky leaps before reaching Col de la Crosatie.
