Leyen pond

Highlight • Lake

A water lily pond/lake cannot present itself more idyllically. The digging wild ducks round off the whole thing perfectly. There are wonderful photo opportunities here. As part of a hike in the Wahner Heide, you should definitely include this highlight. I don't even dare to imagine how beautiful the pond/lake is when the water lilies are in bloom.

View of Dornheckensee

Highlight • Viewpoint

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.

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.

Especially in the morning it is very nice to cycle in the Siegaue. The paths are well developed and the floodplain itself is very well maintained.
