The park contains the Marais-Vernier, the largest peat bog in France, which is a remnant of a former river meander.
The Brotonne Forest, located within the park, covers approximately 6,700 hectares and is known for its protected deer populations.
The Seine estuary tides penetrate deep into the park, creating a 'mascaret' (tidal bore) visible during high spring tides.
The park features the 'Route des Abbayes,' a designated path connecting several historic monastic sites along the river loops.
It is home to the 'chaumières' (thatched-roof houses), a traditional architectural style using local reeds and oak timber.
The Parc naturel régional des Boucles de la Seine Normande spans over 80,000 hectares along the Seine estuary between Rouen and Le Havre. It encompasses a landscape of chalk cliffs, limestone plateaus, wetlands, and extensive forest massifs like the Brotonne Forest. The territory is defined by the winding loops of the Seine, which create a unique microclimate supporting both Mediterranean and northern flora. It incorporates 77 communes and features a significant concentration of religious heritage sites, including the abbeys of Jumièges and Saint-Wandrille. The park serves as a regional hub for migratory birds, particularly in the Marais-Vernier area. Agriculture remains a core component, with traditional orchards producing cider and pommeau. It functions as both a protected environmental zone and a lived-in cultural landscape with specific zoning for biodiversity conservation.
