A superb section of play amidst the rocky terrain. Take this short detour to admire the ruins of Linchamps Castle, a medieval fort whose origins are uncertain due to a lack of documentation.

Unspoiled nature; beautiful grassland next to water. Watch out for mosquitoes in autumn!

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.

We just completed the hike, which is magnificent. Physical but superb. 14.7 km and 490 km of elevation gain. A little info: The Naux footbridge is closed due to severe corrosion. Probably for quite some time, unfortunately. It's impossible to cross. We must continue to the Thilay bridge.
