The Allalinhorn is a mountain in the Swiss Alps, located in the canton of Valais within the Pennine Alps range. Its summit reaches an altitude of 4,027 metres (13,209 ft) above sea level, making it one of the Alpine four-thousanders.
Geography
The Allalinhorn lies north of the Matterhorn and east of the Rimpfischhorn, forming part of the ridge that separates the Oberaletsch Glacier to the west from the Allalin Glacier to the east. The mountain is situated near the resort town of Saas-Fee, which is often used as a base for ascents.
Topography
The mountain’s prominence is approximately 230 m (755 ft), with the key col located at the Allalin Pass (3,797 m). The Allalinhorn’s summit is characterized by a pyramidal shape composed of crystalline gneiss and granite.
Climbing History
The first recorded ascent of the Allalinhorn was made on 28 August 1856 by Swiss mountaineer Alfred Wills, guided by the local alpinists Christian Almer and his son. The route employed was a glacier approach over the Allalin Glacier, followed by a rock scramble on the north-eastern ridge.
Routes
The most frequented modern route is the “Allalin Hut” (Almagellerhütte) approach, which begins at the Saas-Fee cable car station, proceeds across the Hohsaas plateau, and ascends via the Allalin Glacier to the Allalin Hut at 2,905 m. From the hut, climbers follow a moderately steep snow and ice slope to the summit ridge. This route is graded F (facile) in the Alpine grading system and is considered one of the easier four‑thousander ascents, often used for guided tours.
Alternative, more technical routes include:
- The north‑west ridge (graded PD+), involving mixed rock and ice climbing.
- The south‑west face (graded AD), a steeper, less frequented line demanding advanced ice-climbing skills.
Access and Tourism
The Allalinhorn is a popular objective for mountaineers due to its relatively straightforward ascent and proximity to alpine infrastructure. The alpine hut system, notably the Allalin Hut, provides accommodation for climbers and hikers. The mountain is also visible from several ski areas in the Saas-Fee region, contributing to its prominence in local tourism marketing.
Environmental Considerations
Glacial retreat, attributed to climate change, has affected the Allalin and Oberaletsch glaciers, influencing the condition of ascent routes and necessitating updated safety assessments for crevasse hazards.
Cultural References
The Allalinhorn appears in various alpine guidebooks and climbing literature as an exemplar of an accessible high‑altitude summit. Its name is derived from the local dialect, combining “Allal” (a nearby alpine pasture) with “horn,” a Germanic term meaning “peak.”
