Alb River

The Alb rises southeast of the Teufelsmühle mountain at about 743 m above sea level. NN. From here on it flows in a northerly direction through an initially deeply sunk, broad-bottomed valley. It cuts through a valley step in the narrow valley of the Kluse and forms a small, previously artificially elevated waterfall. Below the spa town of Bad Herrenalb, which is towered over by the rock faces of the Rotliee, the valley slopes are significantly lower, and the gradient of the small river has decreased. In this section of the valley lies Frauenalb with its monastery ruins. At Marxzell the Alb takes on the Maisenbach from the right. At Fischweier the Moosalb flows to the left. At Busenbach its course turns to the northwest. Large parts of the floodplains of the Alb and its tributaries in the northern Black Forest have been part of the Albtal and Seitentäler nature reserve since 1994. The Albtalbahn, which runs in the valley floor, connects Bad Herrenalb with Ettlingen and Karlsruhe.
