The Ruhrhöhenweg is a long-distance hiking trail that accompanies the Ruhr from its source at Winterberg in the Hochsauerland to its confluence with the Rhine at the Rhine Orange sculpture in Duisburg. The 219km long Ruhr is the king of the rivers in North Rhine-Westphalia, not only because the Ruhrgebiet, the largest industrial region in Europe, developed along the Ruhr, to which Germany owes a lot of prosperity, but also because the Ruhr represents more like hardly any other river the diversity of the North Rhine-Westphalian landscapes.
