Giesbach
A roughly 8.3 km stream that rises in the Königsforst and finally splits into two arms that seep away in ponds – with a water-treading station at a tri-city point.
The Giesbach is a stream of around 8.3 kilometres that rises in the Königsforst and flows across the Wahner Heide as far as Rath/Heumar. At its water-treading pool, three cities meet at a single point.

Source and setting
The Giesbach begins in the Königsforst north of Forsbach, at the point where the Brück-Forsbacher Weg starts in the east. From here it turns to the south-west, a direction it keeps for its entire course.
One spot is particularly special: at the water-treading pool on the Rath-Forsbacher Weg, the municipal boundaries of Cologne, Bergisch Gladbach and Rösrath all come together — a tri-border point in miniature that you can cross in a few steps.
Course and outflow
Beyond the water-treading pool, the stream first passes beneath Rösrather Straße and then under the A3 motorway. With that it leaves the woodland behind and enters the Wahner Heide, running along the southern edge of military training pond 3. Here, too, water and paths keep crossing: the Giesbach passes under Bensberger Straße and the Heumarer Mauspfad.
The stream comes to an end on the grounds of Schloss Röttgen in Rath/Heumar, where it splits into a main and a secondary arm — both seep away into ponds rather than flowing into any larger body of water.
