View of Dornheckensee

Highlight • Viewpoint

After the completion of basalt mining in Oberkassel, some of the quarries filled with water. The Dornheckensee is the largest and deepest of them. It goes down to a depth of 20 meters under the water surface. Rock falls and undercurrents make swimming a life-threatening undertaking. A forester was once an eyewitness when an edge broke off and disappeared into the lake together with the oak tree growing on it. There have also been dead people who were caught by undercurrents and could no longer escape the ice-cold deeper water layers. Swimming seems rightly forbidden here!

Nice hiking trail along some ponds in the nature reserve. Quite crowded at the weekend, as it is one of the most popular routes for the people of Rheinbach.

Berggeistsee

Highlight • Lake

The "Berggeistweiher" is one of more than two dozen bodies of water in the "Ville" between Brühl and Liblar, which offer hikers a wonderful variety of walks in the woods. Historically, today's nature and landscape conservation area in the "Rhineland Nature Park" is a former mining area, where lignite was mined in opencast mines long ago.

August 27, 2023, Eulenbach Ponds and Stream in Rheinbach City Forest

The Eulenbach has dug deep into the terrain and the drought of the past summer has left its mark on the ponds. The water system seems to be completely out of balance here.

For the Siegauen you should actually take some time for flora & fauna. Coincidence or not, I even saw a couple of storks in the meadows.
