OverviewBrunat-Perroux Route (Aiguille de l'Index)
Aiguilles Rouges may appear small mountains when compared to the giant lying in front of, on the contrary they are fine mountains, in addition to really being a great balcony, giving magnificent views over the massif of Mont Blanc. Actually this fascinating range is rather wide and consists of many interesting summits. Moreover the setting is gorgeous and these peaks offer several interesting climbs.
One of these latter is Aiguille de l'Index, or simply Index, a popular rocky peak resembling an index finger as seen from the village of La Praz, near Chamonix. 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.
