There are days in the mountains where everything is perfect. This day, the weather and conditions were wonderful. “Contamine-Grisolle” in Tacul is a classic route that does not go out of fashion. It is close, never very hard, there is snow, ice and magnificent rock. The couloir is climbed with a tightrope, then we take the time to climb the difficulties in several length of rope. For the return, we follow the track of the normal way of “Mont Blanc du Tacul”.
