The Allalinhorn (4,027 m (13,212 ft)) is a mountain in the Pennine Alps in Switzerland.

It lies between Zermatt and Saas-Fee in the canton of Valais, and is part of the Mischabel range, which culminates at the Dom (4,545 m).

It was first climbed by London barrister Edward Levi Ames, a member of the Imseng family and Franz-Josef Andenmatten on 28 August 1856.

[2] The building of the Metro Alpin funicular to the Mittelallalin (3456 m) just below the north-east face has turned the mountain into one of the easiest and popular 4000-metre peaks of the Alps,[3] when climbed by the standard route (WNW Ridge, difficulty Grade F).

On the normal route, climbers can ride up to the Mittelallalin; from there, there are only about 500 vertical metres to tackle.
