The Our Nature Park is a nature park in north-eastern Luxembourg.<ref name="protectedplanet">{{cite web|url=https://www.protectedplanet.net/16358|title=Parc naturel de lOur / Naturpark Our|website=Protected Planet|accessdate=2023-02-11}}</ref> Geography The park is located in the Ardennes on the Luxembourg side of the Our river, on the north-eastern edge of Luxembourg in the border triangle with Belgium and Germany. It covers an area of 306 km² and with around 16,000 inhabitants the area of the 7 municipalities Clerf, Kiischpelt, Parc Hosingen, Putscheid, Tandel, Ulflingen and Vianden. It is part of the binational German-Luxembourg Nature Park and borders on the German-Belgian nature park Hohes Venn-Eifel. Landscape and ecology The area consists largely of a plateau formed from shale rock, which lies at an altitude of about 500 m. It is broken through by numerous valleys such as those of the Our and Clerve. While the steep slopes of these valleys are mostly forested, the plateaus are more densely populated and are also used more intensively for agriculture. There are many wet biotopes in the river valleys as well as on the plateaus, which represent important habitats for endangered animal and plant species. Among other things, the endangered black stork nests here, the freshwater pearl mussel, the wild cat and the hazel grouse can also be found here. A major ecological problem in the park is the conversion of the original deciduous and mixed forest and the tan hedges that characterize the landscape into spruce monocultures due to intensive forest use in recent decades. Nevertheless, several thousand hectares of tan hedges have been preserved, which still characterize the landscape over long stretches. Tourism The park is a popular hiking area, with numerous long-distance and themed hiking trails and educational trails. There are also many cycle paths and mountain bike trails, as well as Nordic walking trails and high ropes courses. Furthermore, the numerous castles, especially Vianden Castle, are of great importance for tourism. Other sights include the Vianden pumped storage plant, the world-famous photo exhibition The Family of Man'' and the Benedictine Abbey in Clervaux, the border triangle near Ouren, the tunnels of the copper mine in Stolzembourg and the escape route around Ulflingen. The visitor center of the nature park is in Hosingen. History The forerunner of the nature park was the municipal association SIVOR (Syndicat Intercommunal de la Vallée de l'Our), which was formed in 1992 by the municipalities of Heinerscheid, Hosingen, Putscheid, Vianden and Weiswampach. In 1995 Bastendorf,
