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.
