View of Dornheckensee

There is a beautiful view over Bonn from an observation platform. At the foot of the platform is the Dornheckensee, which shimmers turquoise in the sunshine.

After the completion of the Oberkassel/Ramersdorfer basalt quarrying in the 19th century, some of the up to 70 sMeter deep quarrying sites filled with groundwater. Embedded in cliffs, the Dornheckensee today offers a beautiful panorama. Signs indicate that swimming is prohibited here. Rock crumbles off the steep walls of the Ennert and falls into the lake. A dangerous undercurrent can be very dangerous for inexperienced swimmers. Today, the area around the Dornheckensee belongs to the Siebengebirge fauna-flora-habitat area and is subject to strict supervision. A walk around the lakes is recommended, because you can enjoy a unique view above the cliffs enjoy over Bonn. However, care should be taken not to leave the forest paths.
