Mont Blanc : How long does it take to get to the summit?
That depends on several factors – which route you are on, how fit you are, the snow and weather conditions and how acclimatised you are. A strong, well acclimatised team, finding good snow conditions might take only 3-4 hours from the Gouter Hut to the top. However, ill prepared and unacclimatised teams may end up spending the night in the open. To allow for some training, acclimatisation, and a serious summit attempt you should plan on spending at least a week in the area.
