On the viewpoint Pic du Diable you can enjoy a wide panorama of the meanders of the Semois, the deep forests and the Mill of l'Epine. The road to Corbion offers spectacular views of the Semois. The return to Bouillon takes you along small paths through dense deciduous forests and on the 'Rocher du Pendu' offers a fairytale view of the landscape and the Abbey of Clairefontaine. Along the course you will see the Park of the Arboretum with many ancient trees and 'La Ramonette', the site where the first wooden castle of Bouillon was built. It is a tiring trail, but wonderful and it will certainly tempt experienced hikers.
