The Baie de Somme, on the Picardy coast of Hauts-de-France, is a wide estuary of sand flats, salt marsh and tidal channels, and Le Hourdel, reached by the Chemin des Douaniers near Cayeux-sur-Mer, sits at the southern edge of the bay. The point is known for its colony of grey and harbour seals that haul out on the sandbanks at low tide. The typical frame looks out across the flats with the seals as midground subjects, the shining wet sand as foreground reflecting the sky, and the far shore of the bay in the background. Low tide at dawn gives the best conditions: the flats are exposed, the light is soft and the water left in the channels mirrors the sky. Because the sun rises over the land, side and back light create a gentle glow on the sand and water, and calm, clear mornings give the strongest reflections. October to February is best for seal pups, while August sunsets offer colour over the bay. Tide tables must be checked before any visit, since the tide rises quickly across the flats and walking out on the sand is dangerous; photographers should stay on marked paths and observe the seals from a distance. Seals are protected, so approaching closely is discouraged and a 100–400mm telephoto lens is the standard tool, with a tripod for stability. A waterproof bag protects kit from spray and wet sand. The spot is quiet at dawn, becoming busier with walkers and boat trips later in the day. Access is free, and tripods are permitted on the public path. Drones can disturb the seals and are restricted in the protected bay. Restrooms and water are in Le Hourdel and Cayeux-sur-Mer.
