    Overview

    The East Frisian Islands are a chain of islands in the North Sea, off the coast of East Frisia in Lower Saxony, Germany. The islands extend for some 90 kilometres (56 mi) from west to east between the mouths of the Ems and Jade / Weser rivers and lie about 3.5 to 10 kilometres (2.2 to 6.2 mi) offshore. Between the islands and the mainland are extensive mudflats, known locally as Watten, which form part of the Wadden Sea. In front of the islands are Germany's territorial waters, which occupy a much larger area than the islands themselves. The islands, the surrounding mudflats and the territorial waters (The Küstenmeer vor den ostfriesischen Inseln nature reserve) form a close ecological relationship. The island group makes up about 5% of the Lower Saxon Wadden Sea National Park. The largest island by surface area is Borkum, located at the western end of the chain; the other six inhabited islands are from west to east: Juist, Norderney with the largest town in the islands, Baltrum, Langeoog, Spiekeroog and Wangerooge. There are also four other small, uninhabited islands: Lütje Hörn east of Borkum, Memmert and Kachelotplate southwest of Juist, Minsener Oog, a dredged island southeast of Wangerooge, and Mellum at the eastern end of the island chain which, following the boundary revision by the Federal Office for Nature Conservation, no longer belongs to the East Frisian Islands, but to the mudflats of the Elbe-Weser Triangle (Watten im Elbe-Weser-Dreieck).
