Wadden Sea, Denmark

Wadden Sea, Denmark

The Wadden Sea refers to a shallow sea and wetland area stretching from the northwest of the European continent to the North Sea. It begins along the southern coast of Denmark, extends southward to the German coast, then turns westward toward the Netherlands. This is a relatively flat, expansive temperate coastal wetland environment, formed through complex interactions of physical and biological factors, resulting in numerous transitional habitats and tidal channels, sandy flats, seagrass meadows, mussel beds, sandbanks, mudflats, salt marshes, estuaries, beaches, and dunes.

The waters here are full of shallows, making it one of the world’s most famous areas for mudflat hiking. From June to early September each year, on weekends, the sea is dotted with people carrying backpacks carefully wading through the muddy flats. The listed sites make up 66% of the entire Wadden Sea area, home to countless animal and plant species, including marine mammals such as harbor seals, gray seals, and harbor porpoises. Up to 12 million birds breed or overwinter here annually, with over 10% of 29 species found living in the area. It is one of the few remaining large-scale natural intertidal ecosystems where natural processes remain largely undisturbed.
