The Aletschhorn (4,193 m (13,757 ft)) is a mountain in the Alps in Switzerland, lying within the Jungfrau-Aletsch region, which has been designated a World Heritage Site by UNESCO. The mountain shares part of its name with the Aletsch Glacier lying at its foot.
The Aletschhorn, the second highest mountain of the Bernese Alps after the Finsteraarhorn, is the only one of the higher peaks that lies completely in Valais. It is the culminating point of a chain running parallel with the dividing ridge, and surpassing it in the height of its principal peaks. Standing thus between the principal range of the Bernese Alps and the Pennine chain, it shares with the Bietschhorn the advantage of occupying a central position in relation to the high peaks around it. The Aletschhorn is often thought to command the finest of all the panoramic views from Alpine summits.
On its northern flank lies the Aletschfirn, which is part of the Aletsch Glacier. On the southwest lies the Oberaletsch Glacier and, on the southeast, lies the Mittelaletsch Glacier. Both are in the catchment area of the Massa river, which originates in the Aletsch Glacier and ends up in the Rhone river. Its remote location in the middle of glaciers means that the Aletschhorn, despite its height, is less frequently visited and less well known than the summits of the Jungfrau and the Eiger, which lie about 10 km on the north.
