About this place
Wyssnollen (also spelled Weissnollen) is a high-alpine summit of about 3,590 m in the Bernese Alps, in the Swiss canton of Valais. For the municipality of Fieschertal it is one of the goals on the glaciated fringe of the Finsteraarhorn massif. It is a modest glacier tour rather than a technical climb, but the whole route runs over glaciated ground.
Where is Wyssnollen?
The peak rises beside the Grünhornlücke pass, which separates it from Gross Grünhorn. The pass sits at roughly 3,286 m and is a standard link between the Finsteraarhornhütte and Konkordiahütte huts. The area belongs to the Fiescher glacier system, which flows down toward the Fieschertal valley.
How do you climb it?
The normal route approaches from the east and the SAC route portal grades it F (easy). Allow 2.5 to 3 hours and about 690 m of ascent. In winter and spring the east flank makes a half-day ski tour from the Finsteraarhornhütte, with a descent of around 600 m.
A harder alternative is the north-west ridge, starting from the col between Gross Grünhorn and Wyssnollen. It is graded WS and takes about an hour from the col. Climbers often combine it with a hut-to-hut crossing.
What is its history?
The first ascent took place in 1889. The mountain has remained an accessible objective in a region where most summits are far harder.
When to go and what to bring
You are on glacier all the way, so bring crampons, ice axe, rope and crevasse-rescue skills. Spring is a good time, with the Finsteraarhornhütte as a base. In bare ice or fresh snow, even a route rated easy should not be underestimated. Check conditions with the hut or local mountain guides.
