Belle Dune Aquaclub is an aquatic leisure centre located in Fort-Mahon-Plage on the Côte Picarde in northern France, close to the Bay of Somme and the Marquenterre nature reserve. The facility serves as the aquatic hub for the Belle Dune holiday resort, offering indoor and outdoor pools, water slides, and recreational water areas designed for families and groups. The seaside setting of Fort-Mahon-Plage provides guests with easy access to wide sandy beaches and the natural dune landscapes of the Picardy coast. The aquaclub is well suited for families with children of all ages seeking water-based fun in a comfortable, supervised environment, and pairs naturally with the broader outdoor activities and coastal scenery that make this stretch of the northern French coast a popular holiday destination.
