National Nature Reserve of the Bay of Somme

The National Nature Reserve of the Bay of Somme is a protected area along the northern French coast with mudflats, salt marshes, and coastal dunes. These distinct natural zones are shaped by the estuary's tidal movements and create habitats for hundreds of bird and animal species.

The reserve was established in 1994 to protect France's largest estuary and its ecological systems. This decision came after growing recognition of the area's importance for seal and bird populations that depend on the tidal landscape.

Locals and visitors view this protected area as essential to understanding the region's relationship with coastal wildlife and tidal ecosystems. The reserve reflects how communities have learned to coexist with the rhythms of seals and migratory birds that define this landscape.

Multiple observation points equipped with binoculars and telescopes allow you to watch seals resting on sandbanks and hundreds of bird species throughout the year. The best viewing conditions occur at low tide when wildlife is most active and visible.

This area contains France's largest seal colony, which rests on sandbanks during low tide and swims in the brackish waters during high tide. These seals return regularly to the same sandbars in groups, making them dependable subjects for visitor observations.
