Route: Walk of Wisdom (Netherlands)

The Walk of Wisdom is a marked trail around the city of Nijmegen, crossing the Dutch-German border. It is a modern non-religious pelgrimage route. It consists mostly of trails, stringing together natural areas, like the floodplains of the Ooij and Beuningen, the hilly wooded areas of Berg en Dal and the Reichswald, heath areas of Mookerhei, and the fens of Hatertse & Overasseltse Vennen. A very diverse route, often walked in the stages, where the modern pelgrims collect a 'pigeon ring' for every finished stage.
