'The Queen of the Belgian rivers'. Deep in the Ardennes and Gaume, the most beautiful wild river in Belgium and northern France flows into countless wild twists: the Semois/Semoy. It originates on the plateau of the Arelerland (Pays d'Arlon) in the middle of the capital of the province of Luxembourg, Arlon. In the gently undulating Gaume, the Semois turns from a stream into a river and gently flows through green meadows, on the way to the hard Ardennes massif.
