OverviewBrunat-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.
The starting point to get the Aiguilles Rouges massif is the town of Chamonix, in the French side of Mont Blanc Group.
