Lake Harkort begins about 2 km west of the confluence of the Volme and the Ruhr, and extends to the west.
The northern shore of Lake Harkort is particularly popular: The attractive boardwalk, which runs along the lake from Herdecke, is used by walkers, cyclists and skaters alike. The Ruhr Valley cycle path also runs here. Its inviting culinary offering, mini-golf, boat rental and leisure pool (a natural pool) await visitors and the passenger ship MS "Friedrich Harkort" encourages you to take a trip around the lake. Harkort lake is a lake popular among young and old alike and therefore quite busy.
