Walking Across the Floor of the Sea

Along the North Sea coast lies a strange and beautiful stretch of coastline known as the Wattenmeer, where the sea itself seems to change its mind twice a day. Each morning and again each afternoon, the water withdraws for kilometres, laying the seabed bare beneath the open sky. Walkers gather at its edge, remove their shoes, and step out onto what was, only hours earlier, the floor of the sea.

The mud is soft and startlingly cool underfoot, squeezing up between the toes with every step. Far from being empty, the flats teem with quiet life: tiny shells, scurrying crabs, and the curling casts that worms leave behind in the wet ground. A guide leads each group towards a distant island, checking the time constantly, for the exposed seabed is never truly given, only lent by the sea for a few short hours at a stretch.

Then, inevitably, the tide turns. The water returns far faster than most visitors expect, racing back across the flats in bright silver lines. This is precisely why nobody attempts the crossing alone. Only the guide knows the safe routes and the narrow windows in which to use them, which is what allows each group to reach firm ground again well before the sea quietly reclaims its floor.
