Welcome to the Wadden Sea World Heritage site
The Wadden Sea is the largest tidal flats system in the world, where natural processes proceed undisturbed. It extends along the coasts of Denmark, Germany and the Netherlands.
The Dutch-German Wadden Sea became World Heritage in 2009, followed by the Danish part in 2014. The Wadden Sea was inscribed into the UNESCO World Heritage List for its globally unique geological and ecological values. Nowhere else in the world is there such a dynamic landscape with a multitude of habitats, shaped by wind and tides. Biodiversity on a worldwide scale is reliant on the Wadden Sea.
Denmark, Germany and the Netherlands have been joining forces for its conservation for over 30 years, taking responsibility of preserving this irreplaceable ecosystem for the benefit of present and future generations.
