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.

According to legend, a wagon and its entire team fell inside. The horses and coachman died, smashing against the stone. Some believe that the ghost of the unfortunate man has been haunting this cursed excavation ever since, and that it's possible to glimpse him after dark...

Undoubtedly one of the most breathtaking places in Revin, but one of the most difficult to reach. It's best to have strong legs. The Godin Hole (the name is uncertain), several centuries old, originated from a prospecting operation in the rock face. It lies at the bend of a small, steep path overlooking the house in the middle of Fallières. "It comes from the search for slate schists. At the time, people were very poor and looked for slate by digging into the rock. There are other similar holes along the stream below, they extend all the way to the Plateau," says Edmond Szelong, a history buff. No one knows exactly when this breakthrough was made, probably in the 18th century. The imposing cavity, dug into this porous rock, inexorably lets water seep through. It fills with every downpour. “Children used to be responsible for emptying it every morning using buckets.”

Super nice viewpoint on protruding rocks in a serene forest. Unofficial possibility for a bivouac.

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.
