You’ve probably seen this charming town in northern Normandy dozens of times before and just never realized it. Its boat-lined harbor was a favorite subject of late 19th-century impressionist painters, including Claude Monet, Pierre-Auguste Renoir, Alfred Sisley, Camille Pissaro, and native son Eugène Boudin (there’s a museum here in his honor). Today, Honfleur is a popular weekend and holiday spot that’s still home to centuries-old half-timbered houses and a harbor rimmed with inviting cafés.
