Willingen is a community in Waldeck-Frankenberg in northern Hesse, Germany, some 80 km west of Kassel. Willingen borders in the north on the community of Diemelsee, in the east on the town of Korbach, in the south on the community of Medebach, and in the west on the towns of Winterberg, Olsberg and Brilon (all three in the Hochsauerlandkreis in North Rhine-Westphalia). Willingen's landmark is the great railway bridge, "Das Viadukt", built about 1918. The community thrives mainly on tourism. There were 1.3 million overnight stays in 2003, and attractions include winter sports and bowling clubs. Among Willingen's greatest events are the International Ski Federation's yearly World Cup Ski-jumping competition at the Mühlenkopfschanze (a ski-jump arena with seats for 100,000) and the yearly "Mountainbike-Event" at the Ettelsberg (mountain) to which 35,000 spectators came in 2005. Nearby lie the trails of Bike Arena Sauerland.
