The Aiguille de Mesure is part of the Aiguilles Rouges massif in Chamonix. As soon as there is enough sunshine or warm temperatures, these mountains offer splendid climbing in solid granite with a good view onto the Mont Blanc massif. The route Songe d'une nuit d'hiver is just one of many quality routes on this mountain and in the chain of the Aiguilles Rouges.
