This seven-day route uses three overnight bases: Rouen on nights one and two, Honfleur on night three, then Bayeux on nights four to six. It moves from Rouen’s Gothic cathedral and Impressionist painting to the timber church and slate-fronted harbour of Honfleur. Bayeux brings a smaller cathedral town, art and local craftsmanship before two very different excursions: Omaha Beach and its cemetery, then the medieval abbey of Mont-Saint-Michel. Collect a rental car when leaving Rouen on day three and return it there on day seven; the two city days can be walked. May, June and September suit the town-and-coast purpose with useful daylight. The early-June commemorations create their own room and access demand, so choose another week if those ceremonies are not the reason for coming. Add a day for Étretat, the Cotentin or another D-Day sector.
