In reply to Mark Collins:
Gross Wannenhorn is quite popular as a ski mountaineering summit.
However, in summer you are almost always alone. Strange, actually, because it has IMO the best views in the Bernese Alps: Right between Aletschhorn to the West across Aletsch Glacier, Gross Gruenhorn to the North, and Finsteraarhorn across Fiescher Glacier to the East.
Also, the steep West face drops down more than 1000m almost straight to Konkordiaplatz, and to the South you can see the Valais panorama from Fletschhorn to Mont Blanc.
Fiescher Gabelhorn next door to the North is even less visited and a bit harder.
