The Beltringharder Koog is an impressive nature reserve in North Friesland, Schleswig-Holstein. The Koog was embanked in 1987 and covers an area of 3,350 hectares, making it the largest nature reserve on the Schleswig-Holstein mainland. It was created in response to storm surges and today serves to protect the coast and promote biodiversity in the region. The Beltringharder Koog has a variety of habitats, including saltwater and freshwater lagoons, wet grassland and tidal floodplains. These diverse biotopes provide habitat for numerous species of birds that breed or rest here. Over 100,000 waders and water birds use the Koog throughout the year, making it a paradise for birdwatchers. Commonly seen species include greylag geese and black-necked grebes. For visitors, there are well-developed hiking and cycling trails that lead through the diverse landscape of the Koog. Tours that start at Lüttmoorsiel and lead along the dike to Lüttmoorsee and further are particularly recommended. Observation huts and viewing platforms on these routes offer excellent opportunities to observe wildlife in its natural environment. The Koog is also an example of successful cooperation between nature conservation organizations such as NABU, the Wadden Sea Conservation Station and the WWF. Together they ensure that this unique ecosystem is protected and cared for.

The 5km out to Hamburger Hallig are well worth it. The concrete slabs are well grouted and are definitely suitable for racing bikes. At the end is the Hallig-Krog restaurant - highly recommended. In the season it fills up quickly after opening.

The Hamburger Hallig is a non-dyked peninsula on the west coast of the Nordfriesland district in Schleswig-Holstein. The name of the Hallig is reminiscent of two Hamburg merchants, the brothers Rudolf and Arnold Amsinck. In 1624 they acquired the dyke rights on the northeast corner of the island of Strand as Oktroy and built dykes by 1628. This is how the Amsinck-Koog was created. The dikes were destroyed by the Burchardi flood in 1634. Only the terp with the “Hamburger Haus” remained and became a salvation for numerous Strand residents during the storm surge. After 1634, the dikes were rebuilt at great expense and survivors of the flood settled. In 1658 Arnold Amsinck died in the “Hamburger Haus” in his Koog after he had invested his entire fortune in rebuilding the dykes. In 1661 the house was demolished and replaced by a smaller one. What happened was described in literature by the Husum writer Albert Petersen in his novel Arnold Amsinck (1921). In 1711 the dikes were so destroyed that the Amsinck-Koog was a Hallig again. It remained in the possession of the Amsinck family until 1760. The name “Hamburger Hallig” was first mentioned in 1781. The house on the Hallig was destroyed by the February flood of 1825. In 1855 a dam connecting the island to the mainland was planned. The dam was built in 1859/60, but broke again in 1860. In 1866/67 a bush dam was built from Bordelumersiel to Hallig. This dam was fortified in 1874 and added a spillway that was closed in 1875. Due to the interruption of the tidal flows, the silt formation on both sides of the dam was greatly accelerated. The experience gained here has had a decisive influence on the further development of land reclamation. In 1878 the tax authorities bought the Hallig and from then on leased it for management. In 1880 an artesian well was built. The dam has been navigable since 1901. In 1908 the Hallig was 96 hectares in size. On April 16, 1930, it was 216 hectares in size including the dyke foreland and was declared a nature reserve. The Hamburger Hallig is no longer an island since it was connected to the mainland by a causeway in 1860. While a land connection via a dam does not, by definition, turn an island into a peninsula, the salt marshes in front of the dam are added here. https://de.wikipedia.org/wiki/Hamburger_Hallig

Great piece out into the Watt. Not quite as ideal for the road bike. Always busy.
