The Hautes Fagnes (from the French; German: Hohes Venn; Dutch: Hoge Venen, English translation: high fens) are an upland area in the province of Liège (Belgium) and nearby parts of Germany, between the Ardennes and the Eifel highlands. Its highest point, at 694 m above sea level, is the Signal de Botrange near Eupen, which is also the highest point in Belgium. A large part of the Hautes Fagnes lies within the German-Belgian natural park Hohes Venn-Eifel.
The Hautes Fagnes consist mainly of moorland and forest, and stretch between Eupen in the north, Monschau in the east, Spa in the west and Malmedy in the south. It is a very rainy (1500-1700 mm per year) and swampy region. Several rivers have their source in the Hautes Fagnes: the Vesdre, Hoëgne , Warche , Gileppe , Eau Rouge, Amblève, Our, Kyll and Rur. There are several artificial lakes in the region.
