This spectacular ridge walk follows the rocky heights above the Ourthe valley and offers several breathtaking views, including the iconic La Roche aux Faucons. The route winds through forest, over stony paths and past clearings where you can spot lizards and orchids bloom in spring. Along the way you pass three viewpoints, two of which have benches. The paths are well marked but sometimes narrow and uneven – sturdy shoes are recommended!

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!

The rock massif of the Roche au Faucons was too hard for the Ourthe, which had to make a large bend here. The Sentier des Crêtes runs here on the outside bend over the rock. Beautiful rocky forest path with magnificent views of the Ourthe bend and surroundings.

The Ninglinspo valley appeals to the imagination of many nature lovers, if only for the name alone. And rightly so, because it is one of the most beautiful areas in the Ardennes in which the most unique mountain river in Belgium flows, the Ninglinspo, a small tributary. of the Amblève. It is a rugged but at the same time breathtakingly beautiful canyon-like environment that is very popular with hikers and nature lovers. This is an extension of the normal walk that also takes you along another river, the Chefna.
