The east ridge offers a beau­tiful pan­o­r­amic ascent to the Wiwan­ni­horn. It is the lon­gest climb on the Wiwan­ni­horn with the 17 pit­ches. High abo­ve the Balt­schie­der Val­ley, it offers varied clim­bing and is very well equip­ped. In the begin­ning, the­re are some lichens, but the hig­her you get, the more beau­tiful the clim­bing beco­mes. It’s more a moun­tain hike and block clim­bing than an actu­al sport clim­bing rou­te. The dif­fi­cult pit­ches rela­te to some short indi­vi­du­al points in the first pitches.
The big edel­weiss bou­quets and a small larch tree at 2985 m are brea­king records. After the 8th pitch, don’t miss out on the crossing to the left to a sur­pri­sin­gly nice crack.
In ear­ly sum­mer, the approach over the steep firn fields can be very tricky.
Des­cent: Over the west ridge or sou­thwest wall, Tritt­ji. Rap­pel­ling over the east ridge is not recom­men­ded, becau­se the rope can get caught in the bould­ers when pul­ling the rope.
Time: 4 – 6 hours from the hut to the summit.
Equip­ment: 12 quick-draws, 50 meters rope and alpi­ne equip­ment depen­ding on the conditions.
