  • NoticeReported 1 May 2025

    The Blatten landslide (May 2025; month precision) closed the Bietschhornhütte approach from Ried and Blatten, which runs through the restricted zone. Use the new approach from Wiler or Kippel.

  • AdvisoryReported 1 Jul 2025

    A new approach to the Bietschhornhütte from Wiler and Kippel opened in summer 2025 (route updated July 2025; month precision): T3, 3½–4 h, 1,200 m, longer than before but without exposed sections. It is not yet officially approved or on maps and is used at your own risk.

The usual normal route: from the Bietschhornhütte (2,565 m) up to the Bietschjoch, across the upper Bietschgletscher to P. 3408, then a long, loose rock ridge with many towers and pitches of III (a few bolts and pegs) to the north ridge and the summit cross. 5–6 hours and about 1,450 m from the hut, a similar time down.

Since the Blatten landslide of May 2025 the Bietschhornhütte (2,565 m) is reached from Wiler or Kippel in the Lötschental: a new, pink- and white-red-marked approach along the Lonza, up forest roads through the 'Obre Wald' and a new path across the 'Tännerra' to the old hut path (T3, 3½–4 hours, 1,200 m). It is not yet on official maps and is used at your own risk. The old path from Ried and Blatten is closed. From the hut a path climbs to the Bietschjoch (about 1¼ hours). Cross the upper Bietschgletscher, now split in two, under the Schafbärg, then gain the broad, blocky lower ridge at about 3,150 m and climb scree to P. 3408. From there follow the long west (more exactly west-south-west) ridge all the way, with many towers, never extreme, and passages of III; there are a few bolts and cemented pigtail pegs. Stay on the crest, where the rock is best: the flanks are loose. Several side ridges branch off south-west, so take care to regain the crest. Where the west ridge meets the north ridge, follow it for about 20 minutes to the summit cross. The SAC gives 5–6 hours and 1,450 m from the hut, ZS-. Descend the same way, with an abseil at the 'red tower' and several hard towers bypassed on the south side (cairned traces). Allow a similar time for the descent, then 1,000 m more to the valley. An alternative is to descend the north ridge to the Baltschiederjoch.

Overview

A shapely, near-4,000 m rock peak (3,934 m) on the south side of the Lötschental, often compared with the Matterhorn and part of the Jungfrau-Aletsch World Heritage Site. Both normal routes are long AD ridges on loose rock, climbed from the small Bietschhornhütte or the remote Baltschiederklause.

The Bietschhorn rises between the Lötschental to the north and the Bietschtal and Baltschiedertal to the south, in the Valais part of the Bernese Alps. From the south in particular it is a striking pyramid, and it misses the 4,000 m mark by only 66 m. Its north-east and southern slopes lie in the Jungfrau-Aletsch UNESCO World Heritage Site, formerly named Jungfrau-Aletsch-Bietschhorn.

No route is easy. The SAC describes every line as long and demanding for much of the way, and the mountain as 'a bit of a china shop' despite its fine shape: on all ridge routes the rock is reliable only on the crest. The west ridge from the Bietschhornhütte (ZS-, III) and the north ridge from the Baltschiederklause (ZS, short IV) are the two normal routes; the east spur (S) and south-east ridge and south face (SS) are serious climbs.

It rewards experienced alpinists who want a big, quiet summit; because it is not a 4,000er, it sees far fewer parties than its neighbours. Access to the Lötschental side changed after the Blatten landslide of May 2025, which closed the old hut path from Ried and Blatten.

Climbing Notes

Requirements: fitness for a 10–12 hour summit day near 4,000 m, confident movement on long, loose ridges with climbing to III (west ridge) or IV (north ridge), glacier skills, abseiling and good route-finding. Many parties hire a guide.

Typical itinerary for the west ridge: train to Goppenstein and Postauto to Wiler or Kippel, then 3½–4 hours by the new path to the Bietschhornhütte (22 places, booking required). Leave early: 5–6 hours to the summit and a similar time back to the hut, then 1,000 m to the valley. For the north ridge, approach the Baltschiederklause from Ausserberg (5½–6½ hours) and allow 5–6 hours from the hut; traversing up one ridge and down the other is a classic.

The season is short: July to September, when the ridges are dry. Snow on the ridges makes them icy and slow. The Bietschhornhütte path from Wiler/Kippel is not yet officially approved and is used at your own risk; check its status with the hut or the AACB before going.

History

The first ascent was made on 13 August 1859 by Leslie Stephen with the guides Anton Siegen, Johann Siegen and Joseph Ebener. Edmund von Fellenberg climbed the west ridge on 19 August 1867 with Peter Egger, Peter Michel and Anton and Joseph Siegen. In May 2025 a landslide buried the village of Blatten at the head of the Lötschental; the hut approach from Ried and Blatten was closed and a new path from Wiler and Kippel was built in summer 2025.
