The starting point for the GR21, Le Tréport is a pretty village with narrow, colourful houses. It is famous for housing the Kahl-Bürg bunker dug by the Germans during the Second World War. But its real highlight is the funicular railway that takes you up to the upper town. From up there, the panorama is breathtaking: in a magnificent tableau, the houses stretch from visitors' feet to the beach below and the cliffs are lost in the horizon.
