The Wahnbachtal is a ca. 30 kilometres long valley. It extends from Much till Siegburg where the creek Wahnbach ends in the river Sieg.
In summer the Wahnbachtalstrasse along the Wahnbach is a popular street for bikers. But also Hiker could have fun there, the pathes leads you through old small villages and untouched nature. On the half way of the valley the Wahnbachtalsperre starts (drink water reservoir). Around the reservoir you can find a lot of interesting places with wonderful views.
You can reach the Wahnbachtal on different ways, car, bus etc.
