I read somwhere in the forum that said Aletsch Glacier ist one of the must-sees in Switzerland. Am just wondering if the hiking activities around Egglishorn, Fiesch etc to see the Aletsch suitable for winter weather like now?
You can certainly go ski touring on the glacier though I think that it would be better in March-April for the weather, length of daylight and the crevasses should be more filled in. I haven't been there but I hear there are routes that would be suitable for a strong-intermediate skier with enough stamina to last a long day out. Plenty of more difficult routes to take as well.
