View of the Agger near Lohmar

The Agger is a tributary of the Sieg. Its source is in Meinerzhagen, and after 69.5 km it flows into the Sieg between Siegburg and Troisdorf. The name Agger is of Celtic origin and means "flowing water"

View of the Aggeraue Nature Reserve

Highlight • Viewpoint

Relaxed cycling, expansive valleys, peace and quiet, close to nature. A break from the stress of the city. Climatic health resorts. That's what the larger villages (and towns) along the Agger River are now calling themselves.
