North of Calais, the windswept North Sea Coast is another popular spot for a coastal camping holiday. Swing by the fortified city of Gravelines, with its sandy beach and postcard-ready blue-and-white beach cabins, then dive into WWII history at Dunkirk. The Belgium border is right nearby, so you can even enjoy a day trip to Bruges or Ypres. You can also explore different options for camping near Calais on Hipcamp.
