Hiking in Essen, Germany centers on water, woodland, and old Ruhr landscapes. Circle Baldeneysee for long lakeside miles, climb to Ruhrtalblick on the Baldney Steig, or wander through Schellenberger Wald past Schloss Schellenberg. South in Kettwig, quiet paths thread the Kettwiger Stadtwald and the Deibachtal, giving this industrial city a surprisingly green hiking edge.
