The Roche Bayart is a striking rock formation in the French Ardennes, closely linked to the legend of the Four Sons of Aymon. According to the medieval story, the magical horse Bayard, carrying the four brothers on his back, leaped over the rock, creating a cleft in the stone with a single hoofstroke. The rock is located near the monument to the Four Sons of Aymon and, together with the surrounding peaks, forms a symbolic tribute to these heroes of Carolingian epic. The area is accessible via a hiking trail that leads visitors past the rocks and through the forest, offering panoramic views of the Meuse Valley.

It's very beautiful... but the second half is a lot of climbing and scrambling, quite tough.

The beautiful hiking trails are partly difficult for hikers because they have been destroyed by mountain bikers or induro bikes.

La Table des Fées, located in the Semois natural park, is an impressive rock pedestal. Naturally formed, this structure evokes a giant table surrounded by local legends: it was used for the antics of fairies, chased from the Hultai hill in Auby.
