Water there. Water gone.

Water. Sometimes it's there. Sometimes it's gone. One day, you can take a swim. Another day, you can walk the very same spot on foot. The tides make it happen, and they make the Wadden Sea a special place. More than 10,000 animal and plant species have adapted to the living conditions amidst land and sea, fresh and salt water. The regular guests also include 10 to 12 million migratory birds. This natural treasure is protected by national parks. The Wadden Sea is transboundary: More than 11,000 square kilometers from the Netherlands via Germany to Denmark, constantly reassembled by salt marshes, dunes, mudflats, and sand. The diversity of species and the originality of the landscape have ensured that the Wadden Sea is recognized as a UNESCO World Heritage Site. As such, it is in line with the Great Barrier Reef and the Grand Canyon, among others.
