Einshorn, Mountain peak in Grisons, Switzerland

Einshorn is a peak in the Lepontine Alps standing at 2,944 meters in the Graubünden region of Switzerland. The mountain features steep rock faces and sits surrounded by alpine meadows and valleys.

The Splügen Pass, once the more important Alpine crossing, lost traffic after the San Bernardino road was opened year-round in 1967. The old pass road and paths survive largely intact, and hikers on the Via Spluga can still follow them. The Einshorn rises directly above the pass and the roadless Val Curciusa.

The name Einshorn follows a Graubünden naming pattern based on the sun's position: a neighbouring 2,457 m peak near Tschappina is described as a summit over which the sun stands at one o'clock. The nearby Mittaghorn reflects the same custom, and the more common Mittag element appears in several other peaks, gaps and knolls.

Summer routes start from Nufenen (1,569 m) via Alp de Rog and La Valeten, or from San Bernardino (1,608 m) via Strec de Vignun, both rated EB and taking about four hours. The south flank from San Bernardino is a T5 hike requiring mountain experience. The north-west pillar and north ridge are rated S to SS and take eight hours; the north face is avoided by climbers.

The Einshorn and Pizzo Ucello form a single ridge, but only one of the two is visible from each side. Drivers on the A13 see the Einshorn before the San Bernardino tunnel and Pizzo Ucello after it, so many believe they passed the same mountain twice.
