The Wadden Sea area is characterised by an ever-changing natural environment due to tidal waters and waves transforming the landscape every single day. The tidal waters are home to an enormous production of worms, snails, mussels and crustaceans in the tidal flats which drain about two times a day. This is crucial for the millions of migratory birds that each spring and autumn descend on the Wadden Sea to eat and rest on their journey.

The Wadden Sea National Park extends from the Danish-German border to Blåvandshuk and covers 1,459km², of which approximately 300km² are on land. It consists of shallow waters, tidal flats, sand banks, barrier islands, tidal channels, sand dunes, marshland areas and salt meadows. The park extends across four municipalities. Tønder, Esbjerg, Fanø and Varde.
