The area around the town of Rennerod presents itself to the visitor as a gently rolling plateau with small forests and green meadows at a rather rough altitude for low mountain ranges. The presented hike leads from Rennerod for a large part over the Westerwald-Steig into the Holzbachschlucht (gorge), one of the oldest Westerwald nature reserves. Already in 1929 Prussian authorities placed the gorge under protection. The visitor is presented with a picture as if painted: Maple, ash and elm trees bend at an acute angle over crystal-clear water that gurgles and falls over mighty stones. Rock walls tower 30 m high steeply into the sky. For tens of thousands of years the Holzbach has worked on this idyll, boring its way millimetre by millimetre through the basalt and creating one of the most impressive brook openings in the Westerwald. Especially as the vegetation is the same as in the past: there are beech hall forests, bizarre dead wood formations and numerous wild herbs. On both sides of the brook a path leads the hikers through nature. Boards with explanations are placed everywhere and make it easier for visitors to identify plants and animals.
