Boucle du Barrage de la Gileppe

Between dam and Westhertogenwald

Length (in km)
15 km

You are invited to take a trip through the forested area of Hertongenwald, known in French as the ‘forêt des Ducs’, on the slopes of the East Cantons of Belgium. The path around the artificial lake created when the dam was built between 1875 and 1878 reveals a landscape of softwood and deciduous trees. The views over the steep-sided valleys, the setting for many streams from the Fens plateau, will delight those who love peaceful atmospheres.

At the end of your hike, two panoramic lifts take you 77 metres above the dam for a well-deserved snack at the top of the Tower. From there, a last look over the region, with a 360° view, will leave you with an unforgettable memory of your day.
