Ruppin Switzerland lies in a wide belt of terminal moraine and runs from Neuruppin in the south to the village of Binenwalde in the north, the largest part of it being situated in the borough of Neuruppin. The central part of Ruppin Switzerland is the nature reserve of Ruppiner Seenrinne with its chain of lakes: the Kalksee, Binenbach, Tornowsee, Zermützelsee, Tetzensee, Molchowsee and Rhin.
