Enchanting paths lead you through the Kurtenwaldbach valley near the Forsbach mill. It's hard to believe that the city is just a stone's throw away. Surrounded by dense forest, you always follow the babbling of the stream.

From the former mill - the mill wheel can still be seen on the outer wall of the building - a section of the path begins that can be described without exaggeration as "wildly romantic". Perhaps an old-fashioned word that some may consider kitschy, but in my view it is absolutely accurate.

The section that leads through the "Kupfersieferbachtal" on the right bank of the Rhine undoubtedly deserves the title "wildly romantic" - which may seem a bit kitschy to some. At the moment, the path can only be managed with a small but manageable climb, as a tree has fallen across the path.

The Naafbach valley is a popular recreational area, as the Naafbach was actually supposed to be dammed to form a reservoir. There have been plans for this since the 1930s, which is why no large businesses have settled there since then and hardly any new development areas have been designated. In 1980 it all came to an end - the Naafbach valley was declared a nature reserve.

At this point it is quite steep and the path is not paved. Things get difficult for strollers and the like here

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