Stay on the left bank of the Diolon; the path becomes somewhat overgrown with grass. The valley becomes very flat. The stream changes its name to the Lac du Col stream! Near a cubic rock, fords the stream to rejoin the path, which climbs steeply towards the hut at the base of the Gnourou chairlift.
(4) The path becomes a dirt track suitable for vehicles, rising gently through the pastures.
(5) Turn right onto the ascending track.
(6) Turn left onto the track leading down towards Roche Rousse and, after a short descent, follow a track to the top station of the Roche Rousse Télémix.
