Boucle du Barrage d'Eupen

Between the dam and Osthertogenwald

Length (in km)
14,5 km

Your walk is a loop in the heart of the superb Hertongenwald, on the slopes of the East Cantons of Wallonia. The path leads around the artificial lake created following the construction of a dam 63 metres high across the river Vesdre in the 1940s. The grandiose landscapes and outstanding view over the lake on one side and the narrow Langesthal valley on the other side will delight you.

After exertion, comfort. You can recover in the ‘Wesertalsperrer’ visitors’ centre where you can take a final look at the superb panoramic view of the lake and its surroundings from the terrace.
