A magnificent hiking trail, but not to be underestimated. Along the hillside, you'll walk through rock formations, some of which you'll have to crawl through, and past viewpoints overlooking the Ourthe Valley. Some caves are accessible, but only after a short, steep climb. Be careful.

Les Tartines is one of the many rock massifs in this valley. 4 vertical, relatively narrow walls made of dolomitic limestone are perpendicular to the valley. At the bottom of the hiking trail there is immediately a rock cavity 'Trou derrière la gare' and then a sharp further climb to the first Tartine. You can cross it on a forest path, but you can also go through it on a more adventurous path. This happens with the first one over the stomach and hands through a man-sized hole. For a moment you feel like a caver here. You can just walk through the 2nd and on the 3rd you get a beautiful view of Comblain au Pont. The forest path leads you further through beautiful forest to the heights of Oneux.
