Classified as a National Nature Reserve, the Marchand Dune is an exceptional environment that is home to half of the species recorded in the Hauts-de-France region.
It is composed of three types of dunes: white dunes, dominated by marram grass; grey dunes, covered with moss and small flowers; and wooded dunes, where sea buckthorn reigns supreme. Each environment offers a unique atmosphere and is well worth a visit.
