Aire municipal close to St Omer and handy stop if going back to Dunkirk. On a marina with canal walks and a small town with a few shops close by . All facilities free but a French van parked on bourne hooked up which looked like he was permanant along with 3 other vans who had leads running to the boatside electric points.(all fishing). This left just 4/6 spaces instead of 7/10.Spoke to a guy who had been there a few times and fulltimed in France and he complained to the council meeting but got nowhere.
