Grand Couronne

Grand-Couronne is a small town in the Seine-Maritime region of northwestern France. It sits inland along the Scarpe River, not on the coast. There isn’t local saltwater diving access, and the town itself isn’t a diving hub. Nearby freshwater options exist in flooded quarries or lakes in the broader region, often used by local clubs for training. If you’re visiting for diving, plan trips to coastal centers along the Manche or explore regional freshwater sites outside the city for training or short excursions.
