Switzerland
The Wiwanni cirque lies above Ausserberg on the sunny north side of the Rhône valley in Upper Valais, on the southern edge of the Bietschhorn group. Around the Wiwannihütte (2470 m) the hut lists about fifty multipitch routes on compact gneiss, from well-bolted alpine plaisir lines on the Wiwannihorn (3001 m) and the Augstkummenhorn to demanding routes for experienced climbers. Ausserberg has a station on the Lötschberg mountain line between Brig and Goppenstein; a toll road continues to Fuxtritt (1851 m), from where the hut is a walk of about 1 h 30. Approaches and descents are alpine terrain with snow patches early in the summer. In 2026 the hut was wardened until 18 October; the climbing season is roughly July to September.

Eight short pitches of 4b to 5a on compact, grippy gneiss slabs above the Wiwannihütte, finishing on a 2880 m summit. Pitches 3 and 4 climb a big steep slab that is the heart of the route. Chained belays and an abseil descent make it the gentlest introduction to the Wiwanni routes, though the starting pitches feel stiff for 4b.

Switzerland · Wiwanni (Baltschiedertal)
A 17-pitch bolted ridge to a 3001 m summit. Three slab and wall pitches of 5a and 5b come first, then a long run of grade 3 and 4 on the crest that many parties climb moving together, with one fine 5a in the middle. A full mountain day: the summit ridge beyond the last bolt and the scrambling descent are part of it.
