Baie d'Authie, Protected bay and estuary in northern France.
The Baie d'Authie extends across 105 kilometers between Côte d'Opale and Côte Picarde, featuring salt marshes, mudflats, and intertidal zones.
The estuary has sustained local communities through centuries with its abundant fishing resources and natural salt production from the marshlands.
Local residents maintain traditional fishing practices in the bay, collecting cockles and brown shrimp according to seasonal regulations.
Visitors can access observation points and walking trails throughout the bay, with information centers located in Berck-sur-Mer and Fort-Mahon-Plage.
The bay hosts a colony of harbor seals that rest on sandbanks during low tide, while over 200 bird species inhabit its diverse ecosystems.
