Sylt belongs to the North Frisian Islands and is one of the most popular holiday destinations in Germany. It is a narrow island with a 40-km white beach and dunes on the western (sea) side and opens to mudflats on the eastern side. Geologically, Sylt originated as a terminal moraine of the Saale glaciation; it was connected to the mainland until a devastating flood in 1362. In the 1920s a rail only causeway was built once again linking Sylt to the mainland.
The island, and especially the city of Kampen, were traditionally known as a meeting place for Germany's high society, and many rich Germans maintain holidays homes on the island.
Classically Sylt is a beach destination and this still remains the main draw of the island. While the landscape of the German coast is beautiful even for those who don't want to swim or bathe, the temperature of the water rarely exceeds 20 °C even in the summer and that it can get rather windy.
