Wadden Sea and Hallig Islands of Schleswig-Holstein Biosphere Reserve, Coastal biosphere reserve in Northern Germany.
The Wadden Sea and Hallig Islands biosphere reserve is a protected coastal area featuring extensive mudflats, salt marshes, and five inhabited islands along the North Sea. The landscape changes constantly with two daily tidal cycles that submerge and expose the seabed.
UNESCO designated this coastal area as a biosphere reserve in 1990 to protect an ecosystem shaped by thousands of years of human settlement. The five inhabited Hallig islands were officially added to the protected zone in 2005.
The Hallig islands are home to communities who have adapted their way of life to live with regular tidal flooding for centuries. Their raised houses built on artificial mounds shape the landscape and show a unique relationship between people and the natural environment.
Check tide schedules carefully before exploring the mudflats, as the area experiences two daily tidal cycles that determine when areas are accessible or underwater. Wear sturdy shoes and waterproof clothing to safely navigate the wet, windy terrain.
The Hallig islands are the only formations of their kind in the world, distinguished by their low-lying, flat structure that extends barely above sea level. During severe storms, entire islands can be submerged, making resident life there truly exceptional and rare.
