(S) Set off from the campsite at the Pré de Chaumette refuge, behind the refuge. Head due north towards the Vallon de La Pierre. The ascent is gradual up to the foot of the pass, which lies to your left.
(1) After crossing the torrents flowing from the Veyrardonne Glacier on the eastern face of the Sirac, begin the ascent through a very rocky landscape on the path shared bythe GR®54and theGRP® du Tour du Vieux Chaillol to reach the top of the Col de la Valette.
(2) Continue with a short descent followed by another climb. Take care, however, as the ground is unstable and covered with slate. Reach the Col de Gouiran.
(3) Continue northwards, descending again to reach a crossroads at the bottom of this descent.
(4) Start the ascent along a very eroded, sloping path which can be very slippery, leading to thethird pass, the Col de Vallonpierre.
(5) Then begin the descent to reach the Refuge and Lac de Vallonpierre, as well as the bivouac area (E), today’s stage.
