The Ardennes (Luxembourgish: Ardennen; also known as Ardennes Forest) is a region of extensive forests, rough terrain, rolling hills and ridges formed by the geophysical features of the Ardennes mountain range and the Moselle and Meuse River basins.
Primarily in Belgium and Luxembourg, but stretching into Germany and France (lending its name to the Ardennes department and the Champagne-Ardenne région), and geologically into the Eifel—the eastern extension of the Ardennes Forest into Bitburg-Prüm, Germany, most of the Ardenne proper consists of southeastern Wallonia, the southern and more rural part of the Kingdom of Belgium (away from the coastal plain but encompassing over half the kingdom’s total area). The southern part of the Ardennes is the northern section of the Grand Duchy of Luxembourg and on the southeast the Eifel region continues into Rhineland-Palatinate (German state).
