Zeterklippen, Granite cliffs in Ilsenburg, Germany

Zeterklippen are three granite rock formations near Ilsenburg with distinct shapes rising above the forest. They form part of a popular hiking route through the Harz Mountains.

The name appears in records from the 15th century in various spelling forms. The area later developed into a popular hiking destination in the Harz region.

The cliffs serve as checkpoint number 10 for the Harz Hiking Badge, a regional initiative promoting outdoor activities in the Harz Mountains.

The Große Zeterklippe is reached from the Molkenhausstern after about 2.5 km: the path climbs through spruce forest, then a steep 0.5 km branch and, after some 200 m, a gentler 0.4 km stretch lead to the summit rock. Iron ladders mounted on the rock are used for the final climb.

Just below the Große Zeterklippe stood the Mattengarten work hut, built when a botanical garden was laid out here as a replacement for the inaccessible Brockengarten on the Brocken.
