In Chamonix, we love crack climbing, espacially when when we can put our own protection.
Almost all routes in high mountain are only bolted for belays, leaving over perfect cracks very clean.
For one pitch ascent, let's try Vallorcine, Le Couteray area. Overhanging nice cracks and magic place !
Don't forget your cams!
Vent d'émotion, alpine mountain guides in Chamonix !
