From the Plan Glacier hut to the Durier hut (3369m) # +700m

From the Plan Glacier hut, (guarded from June to September,) go to the SE (following a path with some steel cables, passing a couple of rock mounds, to descend onto the Miage glacier. Cross this horizontally to the SW to reach the cliff at the foot of the Col de Miage, to the right of an obvious gully and at the foot of a rock spur (large red paint mark.) Climb up the rocky spur, which becomes less and less marked to the col, (steel cables near the top.) The Durier hut is to the left By climbing the spur, stonefall risk is greatly reduced. The path is good so try to stay on it.

Variant : by traversing the Dômes de Miage It is possible to reach the Durier hut in 2 days from Contamine by traversing the Domes de Miage.

Route # +1100m

S Ridge # +685m

From the Durier hut, go up the snow slopes to the right of the ridge. Climb two snow shoulders to the base of a rock spur (3800m, 1h30). Climb to the right by a chimney. If it is iced up, climb to the left, (steeper). Careful, some loose rock! At the top of the rock bastion (3940m, 30min to 1h, abseil chain now in place), go up a steep snow slope to the summit ridge. (4052m), 0h30, 3h00 from the hut).

(If necessary, it is easy to turn back from the summit to the Durier hut, sling in place near the chimney. From the top of the bastion it is more than 60m, foresee a second abseil, lots of rock spikes).

NE Ridge

From the summit go down the NE ridge, very narrow, to Col de Bionnassay (3888m, 0h50), traversing below the crest, depending upon the conditions, or even one person on each side. Be careful of cornices, or if there is a strong wind.
