This is the way from the Aiguilles du Midi down to the Mer de Glace, filmed in September 2011, in the winter there is a rope to hold and a wider track, it's all a bit more precarious in the summer. Lady Collum is 70 years old. This was her second time down, the first time it was very windy and there was no way I was going to use the video! Christophe Rezette http://www.guides-alpes.com/ is the guide, he really earns his money at 3.30.
