Follow the flow of the Semois

All routes start in the heart of Bouillon, at the foot of its legendary medieval castle. From there, riders follow the river upstream into a landscape of endless forest trails, open valleys, and timeless villages — a natural playground built for gravel.

The Parc National de la Semois delivers everything riders love: fast, rhythmic terrain, mixed surfaces, and wild beauty around every corner.
