Vadehavet (Wadden Sea)

The Wadden Sea is not a naturally evolved cultural landscape in the usual sense, but one that was wrested from the sea. Since the Middle Ages, the inhabitants of the marsh have erected dikes, built up artificial mounds, and reclaimed land. Storm surges repeatedly undid this, and the great flood of 1634 claimed thousands of lives and permanently altered the coastline.In Ribe stands Denmark's oldest city, founded around 700 as a Viking Age trading post. The cathedral, the cobblestone alleys, and the high-water marks on the house walls tell both stories: the prosperity from maritime trade and the constant threat from the water. On Rømø, whaling brought money into the country in the 18th century, while on Fanø it was sailing, evident in the thatched captains' houses.Since 2014, the Danish section of the Wadden Sea has also been part of the UNESCO World Heritage, and it has been a National Park since 2010. Twice a year, hundreds of thousands of starlings gather over the marsh in flocks, forming dense formations just before sunset. The Danes call this spectacle Sort Sol, black sun.

The region is sprawling and sparsely populated; without a car, getting around can be a hassle. The Esbjerg–Ribe–Tønder railway line connects the main towns on the mainland, with buses taking over from the stations, sometimes with infrequent service.The islands have varying connections. Rømø is reached via an approximately nine-kilometer-long causeway, and Fanø by ferry from Esbjerg in twelve minutes. Mandø has neither a causeway nor a ferry; only a tidal path leads there, which is submerged at high tide.The tide calendar is crucial everywhere. Mudflat hikes only with a guide, tidal paths only within the specified time windows. The cycling network is well-developed and flat; however, the west wind almost always blows, making choosing your direction a matter of planning.
