Hundsrücken, Mountain summit in Zollernalb, Germany.

The Hundsrücken is a 931.4 m high mountain on the Albtrauf of the southwestern Swabian Jura near Bisingen in the Zollernalbkreis. Its steep northern drop gives views east to Hohenzollern Castle and the Albtrauf up to the Dreifürstenstein, north over the Alb foreland, and west past the Balinger Berge with the Plettenberg to the Black Forest.

On 26 August 1972, heavy rain triggered a landslide in which the saddle between Hundsrücken and Irrenberg slid downhill for 700 metres on the north side. Repeated reactivations have enlarged the slide area from about 20 hectares to over 36 hectares. On a spur of the Hundsrücken, Burg Ror recalls the Walger family, who were feudal tenants of the Counts of Hohenzollern.

The mountain features the ruins of Ror Castle, which belonged to the Walger family who served as vassals to the Counts of Hohenzollern.

The summit is reached on foot; the steep drop on the eastern side faces Burg Hohenzollern and the Albtrauf up to the Dreifürstenstein. The saddle between Hundsrücken and Irrenberg slipped northward in the 1972 landslide, so the ground there is still moving and the scar area has grown from about 20 to over 36 hectares. The Irrenberg-Hundsrücken nature reserve covers 128 hectares; stay on the paths across the dry limestone grassland.

The 128-hectare Irrenberg-Hundsrücken nature reserve, the largest in Zollernalbkreis, grew out of a landslide: on 26 August 1972 heavy rain sent the saddle between Hundsrücken and Irrenberg sliding 700 metres down the north side. Repeated reactivation has enlarged the scar from about 20 to over 36 hectares, and the bare ground now carries rare calcareous grassland.
