As amazing as it is exciting, this beautiful northern region is an unexpected territory to visit! Contrary to what most people might think, no it doesn't always rain and yes, there are lots of activities to choose from! From the old district of Lille (and its unmissable annual flea market) to Saint Omer and its marshes, to the largest aquarium in Europe in Boulogne sur Mer: there are plenty of ideas and there is something to please every taste and age.
