About this place
Balmhorn is a 3,698 m peak in the Bernese Alps, rising above Leukerbad and the Gemmi Pass in Switzerland. The summit ridge carries the border between the cantons of Bern and Valais. This is a mountaineering objective, not a casual hike.
Where is Balmhorn?
The mountain belongs to the main chain of the Bernese Alps, in the western part of the Alps. The summit sits at roughly 46.425° N, 7.694° E. Leukerbad in Valais lies to the south, while the Kandersteg area in canton Bern is on the north side. Maps disagree slightly on height, giving anything from 3,697 to 3,699 m; 3,698 m is the figure you will see most often.
What makes it special?
Balmhorn is a broad, snow-covered massif with a distinct summit ridge, visible across the Gemmi Pass area. For climbers it offers a compact alpine day: glacier travel, an exposed ridge and careful route-finding. The first ascent took place on 21 July 1864, when Frank, Horace and Lucy Walker climbed it with the guides Jakob and Melchior Anderegg, following the Zackengrat ridge.
How do you climb Balmhorn?
The normal route follows the southwest ridge, the Zackengrat, in both summer and winter. It is graded PD+ and the ascent takes about 5 hours. You gain the ridge by climbing the steep slope above the head of the Schwarz Glacier towards the Zackenpass.
Most parties start from Berghotel Schwarenbach, which you can reach from Kandersteg or from Leukerbad. The shorter southern approach goes over the Gemmi Pass: ride the Gemmibahn cable car up from Leukerbad, then walk about an hour to the pass.
The north side is served by the Balmhornhütte, reached from Kandersteg through the Gasterntal valley. On the Lötschenpass side, the Lötschenpasshütte is the usual base.
What gear and precautions do you need?
Bring glacier equipment: rope, crampons, ice axe and harness, plus the skills to move roped on a glacier. If you lack experience, hire a mountain guide in Leukerbad or Kandersteg. Start early and check the forecast, because weather in the Bernese Alps changes quickly.
When should you go?
The climbing season runs from summer into early autumn, once glacier conditions settle. In summer the Gemmi side is easy to reach thanks to the cable car. The ridge is also used as a ski-touring route in winter, but that is an undertaking for advanced parties.
