During low tide, the retreat of the sea exposes fossils embedded in the chalk formations along the base of the cliffs.
The town was a popular holiday destination for Parisian society in the late 1800s, leading to the rapid construction of its ornate seaside homes.
Plage de Mers-les-Bains is a pebbled and sandy beach situated in the Picardy region, defined by its preserved collection of Belle Époque villas along the seafront. The beach is bordered by a long pedestrian esplanade that separates the water from colorful, highly ornamental townhouses dating from the late 19th and early 20th centuries. The coastline features dramatic white chalk cliffs that mark the boundary between the departments of Somme and Seine-Maritime. At low tide, the receding water reveals extensive rocky platforms and sandy expanses suitable for shore fishing and tide-pooling. The beach is accessible via the Esplanade du Général Leclerc, which provides a direct view of the English Channel. It functions as a Blue Flag beach, indicating maintained water quality and environmental standards. The site is geographically adjacent to Le Tréport, allowing visitors to walk between the two towns along the coast.

Wear sturdy footwear as the transition between the boardwalk and the shoreline is composed of shifting pebbles.
Check local tide tables before visiting if your goal is to walk along the cliff base, as high tide submerges the coastal path.
Bring wind protection, as the exposed cliffside location often experiences significant coastal breezes.
Do not attempt to walk along the base of the chalk cliffs during high tide, as the water reaches the cliff face, leaving no escape route.
Respect the private property of the beachfront villas; do not climb on balconies or block private entrances.
