Norderney is one of the seven populated East Frisian Islands off the North Sea coast of Germany. The island is 14by, having a total area of about 26.3km2 and is therefore Germany's ninth-largest island. Norderney's population amounts to about 5,850 people. In 1946 Norderney gained municipal status and belongs to the Aurich "Kreis" (county). On the northern side of the island lies a 14km long sandy beach. The neighbouring island to the east is Baltrum, which lies about 800m (half a mile) away beyond the Wichter Ee. To the west is the island of Juist, about 3km away on the other side of the Norderneyer Seegatt. The entire eastern half of Norderney belongs to the Lower Saxon Wadden Sea National Park. Access to the park is restricted, as it is subdivided in zones of different accessibility for the protection of the wildlife. The status as a National Park also affects all kinds of traffic on the island, while especially car traffic is subject to strict regulations. The mainland is easily reached via ferry operated by AG Reederei Norden-Frisia from the harbour, Norddeich pier near the northern German city of Norden. Norderney also possesses an airport with a 1000m runway.
