Stretching from the final loops of the Seine to rural Vexin hills, Val-d’Oise mixes Impressionist heritage with airport dynamism. Cergy-Pontoise is a planned university town; Pontoise and Auvers-sur-Oise recall Pissarro and Van Gogh. Roissy-en-France hosts Paris-CDG airport, while the Vexin Regional Park offers orchards and limestone villages. Expect suburban houses, village stone homes, and new builds—ideal for travellers and nature-loving commuters.
