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.

Nice to explore the cave. Beautiful spot. After visiting the cave you continue your walk via a very steep descent.

Tickets 24-25 cost 14 euros (adults) and 11 euros (child). The tour lasted more than an hour and was led by a very experienced bilingual guide, well worth it!
