OCTEVILLE-SUR-MER
Exceptional landscapes born from the meeting of land and sea. Initiated in 1992 and officially created in 1997, the Seine Estuary Nature Reserve, the second-largest nature reserve in France, covers 8,528 protected hectares.
Singular, fragile spaces, between land and sea, near the Normandy Bridge, in the communes of Sandouville, Saint-Vigor-d’Ymonville and La Cerlangue.
Fauna and flora that live to the rhythm of the tides and the seasons
Mudflats, salt meadows, ponds, reedbeds and wet meadows are home to more than 500 species of plants and a rich fauna of more than 300 species of birds, 70 species of fish, nearly 50 species of mammals and 13 species of amphibians: seals, eels, spoonbills, toads…
Farmers, reed cutters and fishermen also work in this area which is managed by the nature reserve.
The Reserve Building
At the foot of the Pont de Normandie, on the Seine Bay area (on the tollgate side), the Maison de la Réserve (Reserve Building) offers an educational area for discovering the estuary, in the Avocette room.
An educational path near the hall, between ponds and reed beds, means you can walk along this sensitive area.
Nature events
Numerous guided tours are available all year round organised by the Reserve to discover birds, amphibians, flora, ponds, the work of reed cutters in winter and so on during visits or hikes.
