(1) Turn right onto the balcony path, passing the Baraque du Col Vert. Stay on the balcony path, running parallel to the cliff, and reach the Baraque des Clos, the junction with the path leading to the Pas de l'Oeille.
(2) Stay on the balcony path, reaching the path leading up to the Refuge de la Station du Col de l'Arzelier.
(3) Head west, crossing the cirque formed by the Moucherolle peaks (Grande and Petite).
(4) Continue south-west.
(5) Pass the path leading up to the Pas de la Balme on your right.
(6) Pass the path leading up to Pas Morta on your right and head south to reach the evening’s stop, the Cabane de La Peyrouse (E).
Near the Roybon hut there is water, but after that there is none; occasionally, near the Clôt hut, a small spring flows, but it often dries up in summer, so you will need to make a preparatory trip to leave a water supply at La Peyrouse.
