    After completion of the basalt mining in Oberkassel, some of the quarries have run aground with water. The largest and deepest of them is the Dornheckensee. It goes down to 20 meters below the water surface. Crushing rocks and undercurrents make swimming a life-threatening undertaking. A forester was once an eyewitness, as an edge broke off and disappeared together with the growing oak in the lake. There were also dead people who were seized by undercurrents and could no longer escape the ice-cold deeper layers of water. Swimming seems rightly forbidden!

    Up here you can have a nice break at a table with benches.

    Over a viewing platform you have a nice view over Bonn. At the foot of the platform is a small lake, which shimmers turquoise in the sunshine.

    In addition to the Dornheckensee, there is also the lesser known Mondsee a few minutes' walk away.
