Hörnli, Mountain summit in Zurich, Switzerland

Hörnli is a mountain summit near Zurich that rises to 1,133 meters above sea level. The peak overlooks the surrounding landscape and sits within a region of varied terrain and forest coverage.

In the Middle Ages the Schwabenweg, a branch of the Way of St. James, crossed the Hörnli. Since 2008 the route is part of the Kreuzlingen branch of the Via Jacobi, Swiss national trekking path no. 4, signalled as the Fischingen–Rapperswil leg. At the foot near Steg the last bear in canton Zurich was killed in 1532.

The name Hörnli refers to the whole mountain chain on the right bank of the Töss, from the Tweralpspitz down to the Eschenberg near Winterthur. The summit is called Hörnli-Kulm, and a mountain inn owned by the canton of Zurich has operated there year-round. A local bear story is tied to the Bärtobel ravine on the mountain's flank.

The summit is accessible via marked hiking paths that pass through different elevation zones. It is best visited during daylight hours for safety and better views.

The area displays different microclimates created by the elevation changes across the mountain. This variation supports different plant communities within a relatively small space.
