Part of an archipelago that extends along the German and Danish coastlines, the Wadden islands you see today are a remnant of the former coastal dunes. Admire the wide beaches and vast dunes, marvel at the flora and fauna and explore the sights and specialties of each island. The ferry to the island is, especially at low tide an unique introduction to the World Heritage. Did you know you that Wieringen is called the secret Wadden Sea Island, now part of the mainland it used to be an island.
