The Wadden Sea has been a UNESCO World Heritage Site since 2009. The Wadden consist of the islands: Texel, Vlieland, Terschelling, Ameland and Schiermonnikoog. They are located on the North Sea, in the northwest and north of the Netherlands and can only be reached by boat.

The origin of the Wadden Islands were created by the last ice age when the sea level was about 100 metres below the current sea level. Subsequently, wave action and tidal movements transported sediment from the sea to the coast.

The Wadden Sea is a recognized biological ecosystem found only on the Dutch-German-Danish North Sea coast. Low and high tides alternate here every 6 hours in the extensive system of channels and dry sandbanks. This results in a unique habitat for more than 10,000 (rare) plant and animal species. In addition, the Wadden Sea is also a popular stopover for millions of birds during their migration.
