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.

Picturesque Chefna valley. One of those beautiful streams here, originating on the plateau of the Parc Naturel des Sources. The steep drop and rocky bottom make it unique. The water cascades over the boulders in waterfalls and pools. It flows gently now (July), but it will be raging in the rainy season.

A must-see is this steep part of the Ourthe Valley, bucolic and ideal for climbing, as well as the memory of Charles Quint in the ruins of the Lognes castle! Hiking there is a varied pleasure between the relaxing banks of the river where fishermen and kayakers compete, and the impressive rocks to be bypassed by steep paths. Go hiking there, fun is guaranteed!
