Departure from the Col du Corbier car park.
(S/E) Cross the access road to the pass (D32) and go up Route de l'Arblay. Cross a dead end on the left.
(1) When the road turns right at a hairpin bend, continue straight ahead on a forest track.
(2) Pass the hamlet of Arblay and continue along a path. Further on, descend in switchbacks to the Pas de l'Ours.
(3) Turn right onto a tricky passage that descends via secure steps to the Tire valley.
(4) Cross the stream and climb north-west up an open ridge from where you can see the entire Vallée d'Aulps and Mont Blanc.
(5) Turn right and head north-northeast (view of Lake Geneva). Take several tricky passages equipped with chains. Finally, when the view clears, you will arrive at a fork.
(6) Take the path that climbs to the right towards the Col de Nicodex. Make a hairpin turn to the right, then one to the left. Continue north-east to reach the Col de Nicodex (you can stop at the chalets just below, where there is drinking water in summer).
(7) Take the path that branches off to the right towards Col de Plan Champ. You will arrive at the sign for "Les Vannées".
(8) Then turn right, heading south, and continue climbing towards the Col de Plan Champ. Leave the Chalet d'Ouzon behind on your left and reach an intersection.
(9) Take the track on the right that climbs towards Col de Plan Champ. After a few bends, you will reach the pass.
(10) Take the track that heads south-east, slightly downhill. Soon turn right with the track and descend south-west, more steeply, to the Chalets d'Ouzon.
(11) Continue down the track. Pass two chalets, enter the forest and descend steeply. Further down, take a hairpin bend to the right, then one to the left. Continue straight ahead until you reach a metal staircase on the left.
(12) Go down the stairs. At the bottom, cross the D32 and return to the car park where you started (S/E).
