The Woltz is a prominent river in the far north of Luxembourg, effectively serving as the upper reach of the Clerve river. Rising near the Belgian border, it flows through the ruggedly beautiful Oesling highlands, characterized by high plateaus and narrow, winding valleys. The region's cooler climate fosters unique biodiversity, with the river's wet meadows providing a home to rare plants like Arnica montana. As it heads south, the Woltz flows through the town of Clervaux, where it carves its way past steep slate cliffs, adding to the town's scenic charm. Ecologically, the Woltz is vital for the northern Ardennes, offering essential habitats for various water birds and amphibians within its protected banks. Hikers are drawn to the Woltz valley for its dramatic scenery and well-maintained trails that showcase the powerful geological forces that shaped this highland landscape over millions of years.
