Focal point of the Chamonix Valley, for both mountaineers & visitors. The glacier is the biggest ice-fall in the Alps (3 630m of vertical) &, as a result of the gradient, is also the fastest moving glacier between 1m & 1m 50 each day). In 1786, it was the historical route chosen by Jacques Balmat & Dr Paccard to reach the Europe’s summit, le Mont-Blanc. Les Bossons chair-lift (1 102m long) was built in 1960. In 1962, it was host to the World Championships & local boy Charles BOZON won gold in the slalom.
