The Wiltz river has a length of 42 km (26.1 mi), and a drainage basin with an area of 80 km2 (31 sq mi).


The Wiltz starts in the Ardennes, in Bastogne, a municipality in the Belgian province of Luxembourg. The river is formed to the south of Bastogne by two small streams.

After a course of about 8 km2 (3 sq mi) in Belgium, the river gets into Luxemboug flowing to the east through the Oesling region. In the village of Niederwampach (Clervaux canton), the river turns to the south.

In Kautenbach, commune of Kiischpelt (Wiltz canton), the Wiltz is joined by its main tributary, the Clerve (Luxembourgish: Klierf, German: Clierf).

Finally, the Wiltz river flows into the Sauer river in Bourscheid, Diekirch canton.
