Rock climbing the Aiguille L'Index via Brunat-Perroux in Aiguille Rouges near Chamonix is a great half-day outing. Watch climbing climbing vlog episode, where I explain how to climb Aiguille L'Index via Brunat-Perroux in Aiguille Rouge. This is a classic alpine rock climbing multi-pitch near Chamonix of seven great pitches and a total length of 180 meters. The route follows several off-width cracks and dihedrals, but still offers plenty of slab climbing and face climbing. Rock climbing the Brunat-Perroux to the summit of Aiguille L'Index in Aiguille Rouges finishes off with an immensely exposed ridge, where you can endure the views of the Mont Blanc summit as well as Mont Maudit, but also the town of Chamonix down the valley. Rock climbing Brunat-Perroux in Aiguille Rouges is a bolted route, but bolts are very sparse. Actually, I would say that you only use them for navigation, and you should at least bring a full set of cams of friends. I brought a full set of DMM Dragon 2 cams that I constantly used. All belay stations are properly equipped with two bolts. The alpine climbing route Brunat-Perroux in Aiguille Rouges is graded D+, 5c, which I would say is fairly well graded. The route to the summit of Aiguille L'Index offers plenty of exposed climbing mostly around 5b. I climbed Aiguille L'Index via Brunat-Perroux in Aiguille Rouges with a friend, who had never done an alpine multi-pitch rock climbing route before. I reckon Brunat-Perroux in Aiguille Rouge is a great introduction to alpine multi-pitch rock climbing in the area of Chamonix. You approach Aiguille L'Index by taking the La Flégère lift form Les Praz de Chamonix all the way u to Col de L'Index. From here you hike west (left of the lift station) until you come to the base of Aiguille L'Index. It is pretty straight forward. An alternative route to the summit of Aiguille L'Index, would be to climb the much easier South-East Ridge, which is an AD, 4c, alpine rock climbing multi-pitch route. It might be easier, but it is much more exposed!
