The Aiguille de la Glière can be quickly reached from the Index chairlift. Looking for a more sustained climb than the famous South ridge, we chose the Les Portes de la Chapelle, a TD+ route.
We climbed Acqua concert in Aiguilles de Van (Perrons). The route is not the best we have done but it offers the stunning views.
There are multiple great routes in the Perrons de Vallorcine and A Bigger Bang is definitively one of them with its memorable 7a pitch.
The Kohlmann route is probably less known than the Rebuffat but as nice in my opinion. It is a short route, easy to find, on good granite with a climb mostly on corners.
We did another fun climb in Aiguilles Rouges: the Ravanel route in the South summit of Aiguilles Crochues. 15 pitches/400 meters easy and very scenic, relaxing after the crimps of Aiguille du Belvédère.
Aiguille du Belvédère (2,965m) is a peak in the Aiguilles Rouges massif. The 300 meters of its Southeast face are steep, compact and home of half a dozen of difficult routes.
