The Baie d'Authie is one of the last wild estuaries in northern France, having largely escaped industrial port development.
The harbor seals (Phoca vitulina) in the bay are part of a growing population that uses the sandbanks for resting during low tide.
The estuary's topography changes constantly due to the high tidal range and the resulting migration of sandbars.
The area is an internationally recognized stopover for thousands of migratory birds navigating the East Atlantic Flyway.
The Baie d'Authie is a 'Grand Site de France' candidate area, emphasizing the preservation of its natural landscape integrity.
The Point de vue Baie d'Authie is a designated observation area offering an expansive panoramic vista of the Authie estuary between Berck and Groffliers. It serves as a primary viewing location for the local colony of harbor and gray seals that congregate on the shifting sandbanks. The site is characterized by an evolving landscape shaped by tidal cycles and significant sedimentation. The estuary acts as a protected natural habitat for migratory birds and various coastal flora. Accessible via the Chemin aux Raisins, the site provides a transition point between the urban beach environment of Berck and the rugged nature reserve of the Baie d'Authie. The observation point is managed as part of the regional effort to preserve coastal ecosystems while providing public educational access.

Bring binoculars for clear observation of the seal colonies, which can be distant depending on the tide.
Consult local tide tables before visiting; seals are most easily viewed on the sandbanks during low tide.
Dress in wind-resistant layers, as the estuary is highly exposed to North Sea breezes.
Do not attempt to walk out onto the tidal flats or sandbanks, as the incoming tide is extremely rapid and dangerous.
Maintain a significant distance from the seals to avoid disturbing the wildlife; dogs must be kept on a leash.
