Zeller Horn, Mountain summit in Zollernalb, Germany.

Zeller Horn is a mountain summit in the Zollernalb area that rises to about 913 meters and offers extensive views across the surrounding landscape. The peak displays distinctive limestone rock formations typical of this part of the Swabian Jura.

The mountain is named after the settlement of Zell, abandoned by the 15th century on the territory of Boll, now part of Hechingen. Only the pilgrimage church of Maria Zell survives, standing on the former site of Zell Castle below the summit. The Zellerhornwiese on the western slope was protected as a nature reserve on 14 February 1950.

The mountain draws regular visitors who come to experience the rolling hills and limestone geology of the region. People use the summit as a destination to connect with the natural landscape and enjoy views across the Swabian Jura.

Multiple marked trails lead to the summit from various starting points, and parking is available at the base. The paths are well-signed and suitable for different fitness levels.

On clear days, visitors can see both Hohenzollern Castle and the expansive Swabian Jura landscape from the peak at the same time. This dual view makes the location particularly rewarding for photography and observation.
