Most of the routes can be approached from either the Le Brevent or Flegere lifts.
Simply an amazing collection of gorgeous granite summits along the south side of the Chamonix Valley. Approaches range from 10 minutes to one hour and the possibilities seem endless. Classic lines include the Frison Roche on the Brevent, any routes on the Aiguille l'Index, Chapelle Gliere, or Clocher-Clochetons. Many of the routes are also reatured in Rebuffat's Mont Blanc Massif: 100 Classic Climbs.
Twin 50m ropes, 12 draws, a small set of nuts and cams in the 1-2.5 range, and a few slings will enable you to climb just about anything in the Aiguilles Rouges. Of course a helmet is also recommended. Many routes can be approached in Teva sandals but a pair of normal approach shoes is better for some of the walkoffs. See guide book for more specific route requirements.
These routes can be quite crowded in the summer so get there early and move quick. Also, you'll see lots of stupid and dangerous things occur at the overcrowded belay stands. Climb safe and wear a helmet.
