Brunat-Perroux Route (Aiguille de l'Index)

Aiguilles Rouges are small mountains if compared with the giant lying in front of, but they are really a great balcony, giving magnificent views over the massif of Mont Blanc. Moreover, the fine peaks of this group offer several interesting climbs. One of these is Aiguille de l'Index, or simply Index. On its sunny East face a fine and homogeneous route grading 4b-5b is running on very good gneiss, rough and worked. Another important quality of this route is the variety of the climbing styles on slabs, cracks and little walls.

Approach - From the upper station of the Index chair-lift a short trail heading towards left (SW) leads to the base of Aiguille de l’Index East face (5 minutes).

The route starting point is situated near a slab on the right of a corner closed by a roof.

P2 – Another long pitch; climb the corner again, 5a, and some little walls on the left, 4b, then go slants to right and climb a spur leading to a stance, lying some meters before the middle grassy ledge. 5a, then 4b, 50 m.
P3 – Cross the ledge slants to right and belay at a bolt on a slab, some meters on the right of a little gully.
P4 – Another long pitch; climb directly a slab and some little walls following one another, then go lightly slants to right. 4b, 5b, 50 m.
