Traffic-free bike rides around Viroinval
Around 2026: a beaver dam flooded the GR. Bypassing the submerged area can be difficult if you are carrying a load, with young children, with a stroller. The GR is therefore temporarily diverted, pending development. Signs inform hikers on the ravel, for those going down, and on the GR, for those going up. You can still pass by mountain bike by getting your socks wet... and more in case of a fall, as you can't see well what's under the water.

The Passerelle de Saint‑Joseph, a modern, beautiful cycle bridge, is located in a place where Revin still clearly shows its industrial past. In the 19th and early 20th centuries, this part of the Meuse valley was a hub of the timber industry, hydropower, and rail transport. The footbridge connects the old Saint‑Joseph working-class district with the bank where the railway line and later the Voie Verte were built. Also, pay attention to the beautiful surroundings.

Along the Voie Verte, you glide into Monthermé, a village that still carries its history in its facades. For centuries, the Meuse was a workplace here: log drivers, ironworks, and small industries set the rhythm. Today, you mainly see the quiet echo of that – natural stone houses on the slope, wide staircases that workers once climbed up and down daily, and a village center that has formed around the river.

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.

Semi-buried washhouse covered with a timber-framed roof decorated with festoons. In the 19th century, washhouses served an important social function. They were one of the few places where women could exchange ideas. Washing clothes was also physically very strenuous. Therefore, practicing this activity collectively made it more bearable. Contrary to popular belief, washhouses most often allowed washerwomen not to wash clothes, but to rinse them.
