Beautifully located climbing area on the Ourthe with its own picnic area and here the sound of the river instead of, as is often the case in Belgium, the road and railway line. Actually, there is something for everyone, although the focus is on easier to intermediate routes. The rock is good, but not always perfectly solid.

Unmissable for the Red Cross: Dive into an enchanted kingdom where legends and mysteries weave the fabric of the landscape… This mountain of sand, like a sleeping giant, reveals its heart of stone sculpted by the whims of time. At the dawn of the Jurassic, erosion gently carved out winding galleries, while the main gallery, 15 meters long, arouses a curious fascination. Was it an offering from the ancients, shaped by human hands, or simply the patient work of nature? The flints found nearby whisper echoes of prehistory, silent witnesses of a bygone era. The Trou des Fées, guardian of forgotten secrets, awaits you.
