Wadden

The Wadden (I am not actually sure of which name to use in English) is a coastal region stretching from the north-west of the Netherlands through Germany to the west of Denmark. It consists of the Wadden Sea, large parts of which fall dry during low tide, and the Wadden islands, a string of islands that shields this sea from the North Sea.

The Wadden are very similar to what is called the Outer Banks of North Carolina, off the east coast of the US
