Southwest of Calais, the coastal dunes give way to cliffs that culminate in windswept, 134m-high Cap Blanc-Nez, which affords breathtaking views of the Bay of Wissant, the port of Calais, the Flemish countryside (pock-marked by Allied bomb craters) and the distant cliffs of Kent. The grey obelisk (erected 1922), a short walk up the hill from the parking area, honours the WWI Dover Patrol. Paths lead to a number of massive, concrete German bunkers and gun emplacements.
