The source of the Sauer is, as Sûre, in the southeast of Belgium in the Ardennes Luxembourg province, on the western part of the Rhenish Massif, at an altitude of about 510 m 1.673 ft.

On their way through the mountainous north of Luxembourg the Oesling, it passes through the Lac de la Haute Sure, an artificial lake to the west of Esch-sur-Sûre.
