The Picardy Coast’s territorial organisation is structured around two large urban units, the Abbeville region and the "3 sister towns" Mers les Bains-Eu-Le Tréport, surrounded by other rural areas (Friville-Escarbotin, Gamaches, Crécy-en-Ponthieu, Rue, Saint-Valéry-sur-Somme...).

This entire area therefore has medical, residential, commercial, school, logistical and even tourism infrastructures, which offer its inhabitants day-to-day comfort, leisure activities and local services.
