Siegtal cycle route

A day trip to the river with a pic­nic

The Siegtal (Sieg val­ley) cycle route fol­lows the river through­out.

Sporty cyclists will manage the 67-kilometre route from Windeck-Auf to the confluence of the Sieg river into the Rhine at Niederkassel-Mondorf (or the reverse) in a single day. However, for anyone wanting some variety, it’s well worth taking two or three days time to cycle along the Siegtal route at a leisurely pace and enjoy nature. The tour takes cyclists along broad, unspoilt water meadows and colourful orchards, over dykes and through forests, which with their wide, asphalted paths are ideal for day tripper and leisure cyclists and families, particularly since there is only one challenging climb just before Schladern, at the eastern beginning or end of the tour.

Cyclists will be rewarded with an impressive natural spectacle. Over a breadth of 84 meters, the Siegwasserfall waterfall, the largest in North Rhine-Westphalia, tumbles down over several stages. It was artificially created during the construction of the railway (1857 - 1859), and today is a popular day trip destination for cyclists and hikers.

The route continues towards the west, always following the course of the Sieg river, with the four towers of the Burg Blankenberg castle rising up about halfway along. The castle complex, which was built in around 1150 on the 150 meter-high hill ridge, and the town of the same name with its historic town centre, are ideal for a half-time break before continuing on to the next stage, through the towns of Hennef and Siegburg to just before Bonn. During the final kilometres of the tour, nature is again the star attraction. Cyclists should be sure to stow a picnic basket and camera into their saddle bags.
