Tips from the Community

August 8, 2026, Monthermé

Along the Voie Verte, you glide into Monthermé, a village that still carries its history in its facades. The Meuse was a workplace here for centuries: wood rafters, forges, and small industries set the rhythm. Today, you mainly see the quiet echo of that — natural stone houses against the slope, wide stairs that workers once climbed up and down daily, and a village center that has formed around the river.

Great view of the loop

The panoramic view of Monthermé, along the Sentier des 4 Fils Aymon, offers one of the most impressive views of the Meuse Valley in the French Ardennes. From this elevated vantage point, a picturesque scene unfolds of wooded hills, winding river tributaries, and the charming town of Monthermé nestled in a loop of the Meuse River. The view is a highlight of the hiking trail dedicated to the legendary four brothers and their horse, Bayard, and combines nature experiences with epic folklore. Thanks to well-maintained paths and informative signs, the panorama serves as both a visual and cultural highlight.

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.

What Paul_C said above is nonsense. There is NO "chemin des petitte croix" in this region, although there is one in central and southern France. It's nowhere to be found. So please, if we're going to share information, please make it CORRECT. This cave is only accessible via a few unnamed forest paths.
