About Herdecke
Herdecke is uniquely situated at the confluence of the Ruhr river and two reservoirs, the Harkortsee and Hengsteysee, earning it the moniker 'City between the Lakes.' This geographic position makes it a regional hub for water sports and cycling, while the landscape is defined by the steep, wooded hills of the Ardeygebirge. Visitors can explore local heritage at the Hohensyburg Burgruine or enjoy leisure time at the Park am Bleichstein. The town effectively balances its industrial Ruhr area proximity with extensive green space and riverbank recreation.
