Natursteig Sieg

The Natursteig Sieg hiking trail offers almost 200 km of pure enjoyment for hikers, between Siegburg and Mudersbach. The route travels through the solitary natural landscapes of the Sieg Valley, taking in numerous sites of cultural interest, and amazes visitors with its impressive river landscapes and fabulous views. Narrow tracks rather than broadly-laid hiking trails and an appealing route characterise this remarkable hiker´s paradise.

The entire trail can be comfortably hiked in 14 one-day stages. Numerous railway stations follow the trail along the Sieg Valley, ensuring easy access to the various stage points using public transportation.
