One-way connections between the Theux and Stoumont EXTRATRAIL routes cover a loop of approximately 13 KM passing Charmille (Vert Buisson) and Ville-au-Bois (Stoumont hills).
VIOLET “CONNECTION” markers can be followed for this loop.

You can then explore the small and very popular valley of Ninglinspo (torrent) along with that of Chefna (stream).
