Of course, hikers can find information in advance on relevant websites, for example with the following link to stage 12, which – comparatively short at just under 14 kilometers – leads from Hennef to Stadt Blankenberg (despite being named 'Stadt', it is a district of Hennef) =>> https://www.bergisches-wanderland.de/bergischer-weg/etappen-des-bergischen-weges/etappe-12-von-hennef-nach-stadt-blankenberg-137-km The route description reads as follows: "This stage is full of views, offering new perspectives into the valleys of Bröl and Sieg and, with good visibility, allowing you to discover the Siebengebirge and the Eifel on the horizon. For this, however, some climbs have to be overcome on the comfortable forest paths and dreamlike rocky trails. The school where the idea for the first youth hostel was born, the half-timbered village of Auel and the medieval town of Blankenberg also ensure that there is no monotony in terms of culture and appearance."

The Sülz River flows powerfully through Hoffnungsthal. This tributary of the Agger, approximately 25 kilometers long, significantly shapes not only the townscape but also the surrounding landscape. Densely vegetated banks and open green spaces line the river. During heavy rainfall, the Sülz often swells rapidly, flooding the areas it surrounds.

The Kupfersiefer Valley near Rösrath is a protected landscape area that perfectly showcases the diversity of the Bergisches Land region's valleys. Here, the stream meanders naturally for extended stretches, accompanied by damp meadows, old groves, and wooded slopes. The valley provides a habitat for numerous animal and plant species. As you walk through this approximately 65-hectare nature reserve, you can enjoy peace and quiet far removed from the hustle and bustle of everyday life.

Eulenbroich Castle was built around 1200 as a moated castle and is located in the Sülz river valley, very close to the center of Rösrath. Over the centuries, the building has served many different purposes: as a grand bourgeois villa, as the mayor's residence, and as a retirement home. Since 2003, the Eulenbroich Castle Cultural Association has managed the castle. Today, Eulenbroich Castle is open to the public for concerts, corporate events, markets, seminars, conferences, weddings, communion celebrations, and birthday parties.

At Hauptstraße 310-312 in Rösrath, you can view the historic site of the Reusch Villas (exterior only). The Karl Reusch Villa (built in 1896) and the Kurt Reusch Villa (built in 1894) stand together in a large English-style park with mature trees. These two villas are among a total of four villas owned by the Reusch brothers. The other pink villa can still be admired on "Am Hammer," a street branching off the main street.

"The Sülz Valley takes its name from the Sülz River and its two source streams, the Kürtener Sülz and the Lindlarer Sülz. Measured from the source of the Lindlarer Sülz, the Sülz travels 49 km before flowing into the Agger River near Lohmar. This makes the Sülz the most important tributary of the Agger, which in turn drains into the Rhine via the Sieg River." https://www.ich-geh-wandern.de/suelztal "...The name Sülz is derived from the Germanic word *sula- and describes a marshy place, a wallow, or a pool..." https://de.wikipedia.org/wiki/S%C3%BClz_(Fluss)
