Once upon a time… A verdant landscape crossed by charming waterways and dominated by impressive monuments. In the heart of Aire-sur-la-Lys, surnamed “the Belle of the Pas-de-Calais”, a collegiate church, chapels and a belfry listed as a Unesco World Heritage Site, vie for the limelight with cobbled streets, little flower-bedecked bridges and natural areas such as the Ballastières, a veritable haven of peace right in the center of town.

On foot, by bike or by boat, along the hiking trails or on the banks of the Lys, the area can be discovered in every season and reserves authentic and delicious surprises for its visitors.
