By either of these routes gain the obvious broad ramp that will lead up to the SW Ridge. The ramp may be easy snow but, if not, it is easier to cross to its far side and climb the rock, mainly UIAA 2 and occasionally 2+, to arrive at the shoulder at about 3750m. From here, after a short flat section, follow the ridge (with some moves of 2+ on good rock) initially on the R, then on the crest itself. There are occasional bolts and abseil rings. There is a further steepening below the summit. Traverse L here and climb a short crack which may be icy (UIAA 3-) then move back onto the ridge near a fore-summit. Easier mixed ground leads to the summit itself.

Admire the fine interconnecting ridge to the Lauteraarhorn and all the big peaks of the Oberland, including a great view of the distant Mittelegi Ridge of the Eiger.

Descent is the same in reverse. Printed texts suggest 50m abseils, but this is not needed and may cause rope drag, so do 25m abseils and avoid the need to carry an extra rope.
