Juist rules of the road: no entry except for bicycles and horse-drawn carriages proceeding at walking pace
Juist beach in winter
The tallest buildings on Juist that can be seen from the North Sea are the water tower and an old hotel. There is a lighthouse on the island, but it is not in use. At the western end of the island is the Billreef, a large sandbank where birds such as dunlins, grey Plovers and knots rest during their migration. In the western part of the island the beach and the dunes are eroded by the sea. The edge of the dunes moves about five metres south each winter. On the western third of the island is Lake Hammersee, a freshwater lake.
Juist is accessible by plane or daily ferry. FLN Frisia Luftverkehr operates planes between Norden and Juist. Most motor vehicles are prohibited on the island, with only the fire department, the German Red Cross and doctors allowed to use them. Island tractors require a special license, while most other transport is done by bike or horse-drawn carriage. It was reported by Reuters news agency on the 24th September 2014 that an unmanned "parcel copter" will commence delivery of urgent drugs and supplies to the island by DHL. It will be the first time an unmanned aircraft had been authorised to deliver goods in Europe and the first time that automated drones have been used to deliver medicines anywhere in the world. The flight at an altitude of 50m and at a speed of up to 18m/s will be automated but monitored in Norddeich.
Tourism is the main source of income for Juist's economy. Almost all the buildings on the island feature guestrooms, with several hotels and a youth hostel also on the island. There is an island partnership between Juist and Hiddensee in the Baltic Sea.
In the 17th and 18th century Juist was cut in two parts by several storm tides (see St. Peter's Flood). Around year 1770 people started to close the 2 km wide burst at the southern side by a dune dike. As recently as 1928 the northern side was repaired. By that time, the water in Lake Hammersee had turned from saltwater to freshwater. On September 9, 2001 Juist citizens voted for their mayor directly for the first time, with Karl-Josef Wederhake winning the election. He was re-elected in September 2006.
