You park beside Le Hourdel's tiny harbor—a cluster of weathered shacks on pilings, nets drying in the salt wind—and the beach unfurls northward in a long crescent of smooth pebbles. This is the Somme Bay's wild shoulder, where the river surrenders to tide and grey seals haul out on exposed sandbars at low water. Bring binoculars: on calm mornings you'll spot their dog-like heads dotting the flats half a kilometer offshore, and if you're patient, harbor porpoises finning through the channel.

The beach itself is all shingle—ankles roll on the larger stones near the waterline—but the walking is easy along the upper berm, where driftwood tangles with bladderwrack and your dog can run leash-free for kilometers. Cayeux-sur-Mer lies three kilometers south, but Le Hourdel feels like its own republic: a handful of fishermen's cabins, one café, and a lighthouse blinking at the mouth of the bay. Locals come for moules-frites at the portside shack, then linger as the sun drops behind Picardy's chalk cliffs.
Evening is the revelation. The western horizon opens wide, and as the tide recedes it leaves mirrors of standing water that double the apricot and violet sky. You'll hear oystercatchers piping, smell iodine and mud, and understand why painters have been setting up easels here since the Impressionists worked the nearby coast.
