This first stage starts at the Refuge de l’Orgére.
(S/E) Take theGR®55opposite the refuge. Right from the start, there is a significant climb through the woods. After this first section, as you emerge from the woods, you’ll reach a junction at an altitude of 2,178m, where there are ruins that were likely once a summer pasture.
(1) Turn right and ignore the path branching off to the left. Continue straight ahead (north), still climbing. Pass at the foot of Tête Noire on the left. You’ll reach a flat area at an elevation of 2,502m and a junction. To the left is a beautiful waterfall and to the right, below, is Lac de la Partie.
(2) Continue to the right (north) towards the Col de Chavière (ignore theGR®55which branches off to the left). Climb up to the pass, at an altitude of nearly 2,800m, where a magnificent view awaits you. There were numerous snowfields for the month of August.
(3) Descend from the pass over very unstable scree to reach Plan des Cairns, a place where, as the name suggests, there are a multitude of cairns. To the right, the head of the first glacier on this route, the Gebroulaz, and an imposing rock massif, the Aiguille de Polset, which rises to 3,500m.
(4) Continue northwards along theGR®55to a junction.
(5) Turn left and leave theGR®55. Walk alongside a small lake on your right. Continue to the Peclet Polset Refuge (E).
