Where the Lys crosses Wervicq-Sud, not far from a towpath.

Let the Lys be your guide...

The source of the Lys is in Lisbourg at an altitude of 115m. The river slowly flows past several remarkable sites such as the Verchin castle, before arriving in the town of Aire-sur-la-Lys, situated on the water with stunning architecture. The river leaves the Pas-de-Calais and heads for the North, crossing two towns with grand belfries: Merville and Armentières. The waterway flirts with Belgium where Flemish and French landscapes alternate with cross-border towns full of history. The brewery museum in Comines-Warneton and the tobacco museum in Wervik (Belgium) are signs of the rich heritage. After 7km in the countryside, the Lys opens onto another cross-border town: Menin (Belgium) and Halluin (France) where the river harbour is ideal for relaxing before the 100% Belgium stage.
