The Wadden Sea, located along the North Sea coast, boasts a rich ecosystem teeming with a variety of species. Covering 11,500 square kilometers, this UNESCO World Natural Heritage site extends into the Wadden Sea National Parks of Schleswig-Holstein, Lower Saxony, and Hamburg. Mussel beds, vibrant seagrass meadows, and soft mudflats provide sustenance for numerous animals, while salt marshes along the dunes give way to sandy beaches and islands, including Hallig islets. For migratory birds, the Wadden Sea serves as a crucial stopover, thanks to its fluctuating water levels and diverse habitats. The landscape is continually reshaped by high and low tides that occur every six hours, creating opportunities for mudflat hiking, known as Wattwanderung, allowing visitors to get up close to local wildlife. Seals lounging on remote sandbanks further enhance the charm of this remarkable environment.
