Between the Dornheckensee car park and Oberkassel, the path always runs close to the edge of the breakoff and there are several lookout points from which you can get an overview of the Rhine Valley.

The Heinrichsblick at the nature reserve Rodderberg.
This cozy viewpoint invites with two benches in every season to linger. The great panoramic view offers a view of the Siebengebirge, Königswinter, Mehlem, Bad Godesberg, Bonn and in clear weather Siegburg, the promontory with Wesseling, Bornheim, etc. to Cologne where you can even make out the cathedral and the TV tower.

On Sundays and public holidays there is something more going on, but normally you can rest here in peace and quiet.

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.

The outline of the volcano crater can be clearly seen, and the flora also has plenty of discoveries. Really a great spot of nature, can be well combined with a trip to Rolandsbogen. More here: natur-erleben-nrw.de/natura-2000/regionen-und-gebiete-in-nrw/details/rodderberg

Pollarded beeches in the Kottenforst

Highlight • Natural Monument

The headbooks are witness to a historical forest management. For firewood, the trees were cut off at about 2m height. This meant that cattle driven into the forest could not eat the renewable shoots. The trees are absolutely worth seeing.

Melbtal Nature Reserve

Highlight (Segment) • Forest

It's hard to believe that such a hiking highlight can be found almost in the middle of the city. The path above the old bridge requires surefootedness and sensible footwear (especially if the ground is damp). But it is great fun to walk on the narrow path along the Engelbach and sometimes a little climbing over a tree trunk is necessary.

May 11, 2026, Lava Column of Rodderberg

About 250,000 years ago, the Rodderberg volcano reawakened. A particularly well-visible testimony to the slag eruptions is a fissure filled with lava that penetrated the slag deposits in the northern quarry. The slag was mined, and the basalt dyke remained standing due to its greater hardness. It can still be admired at this spot today. https://www.geocaching.com/geocache/GC1TKGT_rodderberg-vulkan

The pollarded beeches in the Kottenforst Bonn forest near Waldau are mostly common beeches and up to 250 years old. The origin of the pollarded beeches has an earlier agricultural background. Back when wood was still used for heating, so-called forest pastures were established, i.e., meadows were planted with beeches. The beeches were then regularly pruned after 10 to 15 years to a height of approximately two meters. The beeches, which continually sprouted new shoots, grew back, and the cut-off portion was primarily used as firewood.

Very nice for a nature reserve in a city. I prefer less frequented nature reserves (e.g., the Eifel region).

This section is very muddy after the rain. There are dozens of fallen trees. Unfortunately, the bridges have some damage. According to the sign, the path is no longer maintained. What a pity!
