Ecours (1026m) / Charvaz (1512m) / Vedun (1525m) – 3 hrs

The first part of the trail coincides with route number 1: Ecours / Echarlod / Vedun. The path unfolds through the houses of Fenêtre and clambers up through pine woods and xerothermic vegetation, following the ancient mule track that unwinds through series of stone walls and trees. At this point you have reached the deep valley furrowed by the Charvaz torrent. Once you've crossed the torrent, you start to ascend into the woods along a well beaten trail that becomes less accessible amongst the ups and downs of the track, before reaching Montagnoulaz. Beyond the chalets, the trail becomes a track and climbs up the steep slope to finally reach a rocky passageway. Moving diagonally, you cross a canal where the trail is covered by the debris of a landslide. Beyond the trellis you find yourself along a flat track that leads you to the piste that comes from Vedun. The trail then intersects route numer 1 Ecours / Echarlod / Vedun.

The road track passes alongside chalets that find themselves between woods and alpine praries. At the foot of Hôpitaux, leave the road to then take the lane on the right that begins beneath a rocky mountainside.
The trail passes behind houses and climbs up into the woods : within a short amount of time you will reach the farm road once again, after having come across the route indicated as no.3 and no.101, coming from Morgex and Planaval.

An uphill slope then takes you to the crossing of a torrent from which the path that passes over the top of Mount Charvaz branches off. After several ups and downs, the trail comes to a crossroads indicating route no.1 A that takes you to Col-de Bard (1750m). The path then comes to an end as you pass through the fields of Charvaz. You will therefore have to descend towards the left, crossing the pastures until you reach the ruins of an old building.
