The Bröl, which runs in the Bergisches Land and Bergisches Land Nature Park , rises south of the Hermesdorf district of Waldbröler . Its source is north of Landesstraße 324 ( Siegener Straße ) at 368  m above sea level. NHN .

As a low mountain range, the Bröl runs mostly in a south-westerly direction through the Bergisches Land or the area of ​​the former imperial rule of Homburg . Shortly below its origin, it flows through an industrial area between Hermesdorf in the east and Waldbröl in the west. Then it runs via Bröl (to Waldbröl) and henceforth through the Nümbrecht districts of Niederbröl , Grötzenberg , Bruch , Winterborn , Gaderoth and Breunfeld to Bierenbachtal . Then, after passing the Holsteinsmühle ( 208.6  m ), to which a mill ditch leads, it flows north past Homburg Castle , which stands on the Schlossberg ( 280.6  m ).

The Bröl then runs further west between Huppichteroth in the north and Homburg-Bröl (zu Nümbrecht) in the south. Then running south-west again, it flows via Erlinghausen , Schönthal (both to Nümbrecht), Herfterath , Ophausen , Müllerhof , Alefeld (all to Much ), Röttgen (Nümbrecht), Bruchhausen (Much), Bröl , Neßhoven (all to Much), Millerscheid ( Ruppichteroth), Höfferhof , Damm , Bröleck , after which - after crossing under the federal highway 478 - the Waldbrölbach coming from the east joins.

Along the B 478, the Bröl flows past the Ruppichterother village of Büchel and the Herrnstein castle ( 124.6  m ), which belongs to the Ruppichterother district of Winterscheid . There are several large ponds in an old arm of the Bröl. It then flows past Winterscheiderbröl (to Ruppichteroth) and Bröl ( Hennef ).

Finally , the Bröl flows into the Sieg at an altitude of 67  m below or southwest of the Münschmühle district of Hennef .
