"... The Nachtigallental in Königswinter, at the entrance to the Siebengebirge Nature Park, is simply wonderful, at any time of the year. If you walk up Bahnhofsstrasse there, you'll come straight there. You immediately feel like you are in another, serene world. The hiking trail goes around many curves up towards Drachenfels. The Mennesbach babbles next to the hiking trail and the birds sing. When you have arrived at the upper end of the Nachtigallental, you will already see the Drachenburg and then the Drachenfels castle ruins. Saint Bernard and the Nightingales: A legend from the Middle Ages tells how the Nightingale Valley got its name. Once, Saint Bernard of Clairvaux, the great Cistercian monk, was very upset by the singing of nightingales during a visit to Himmerod Monastery. He was so angry that the birds migrated to a valley in the Siebengebirge, which was later called “Nachtigallental”. Saint Bernard moved back to Clairvaux, but from then on music was at home here. The Nightingale Valley is a bird paradise. But not all monks felt like Bernhard von Clairveau, just think of the famous monk von Heisterbach, Cistercians like Bernhard, he liked the singing of birds. ..."

A few bridges were no longer intact and very shaky. But a nice change from normal paths.

Path through the creek valley, but actually a little too well developed due to the fish ponds.

Surprisingly close to nature, the path through the Ahrenbach valley begins here almost on the outskirts of the village.

Climbing on the Stenzelberg has been expressly forbidden since June 2005. Previously, the Rhein-Sieg district had tolerated climbing, although the Stenzelberg, like the entire Siebengebirge, had been designated as a nature reserve (NSG) since 1920. The climbing ban became necessary due to the new nature reserve ordinance in the course of the recognition of the Siebengebirge as FFH area 5309-301 (Fauna-Flora-Habitat) of the European Union. In particular, the occurrence of the wall lizard was concerned and egg-laying sites at the foothills of the fields were destroyed. Despite the ban, climbing continued illegally after 2005. The path to the rocks was therefore closed by the forestry department.

While Sankt Augustin doesn't feature traditional deep canyons like those found in other parts of the world, the term here refers to the distinctive gorges, valleys, and unique rocky landscapes primarily within the broader Siebengebirge region. These include stream-carved ravines and impressive rock formations resulting from volcanic activity and historical quarrying.
One of the most prominent features is the Stenzelberg Rock Formations, a 287-meter-high mountain with a picturesque rocky landscape formed from volcanic rock. Other notable areas include the Tretschbach Valley with its narrow stream and primeval forest, and the Laubach Valley, which is part of the Siebengebirge Nature Reserve.

The Tretschbach Valley offers a unique experience with its narrow stream, wooden bridges, and jetties. Another favorite is the Great hiking trail in the Ahrenbach Valley, known for its rustic path and seasonal flowers.
