This sliver of sand and salt marsh in the Wadden Sea - roughly 74 hectares, last measured - is one of three islands in the Rottum reserve where access is explicitly forbidden. Not restricted.

Zuiderduintjes: The Moving Map

Photo credit Baykedevries, CC BY-SA 4.0. Like the rest of the eastern Wadden Sea, Zuiderduintjes is in slow geographical motion. Its growth between 1995 and 2007 was not a fluke; the island has been gradually building up since formal mapping began in the early twentieth century, even as Rottumeroog next door has shrunk....
