In the heart of the Hautes Fagnes, the lakes at Robertville and Bütgenbach offer two complementary settings: wooded shores and the Warche valley for one, and large beaches and sweeping vistas for the other. Here, the water blends with the Ardennes forests to create a nature getaway combining relaxation, sport and panoramic views.
