GR 16 - Sentier de la Semois (Belgium, France)
'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.
