Niederkassel-Mondorf
Windeck-Rosbach (train station)
The Sieg cycle path begins in Niederkassel-Mondorf, just a few kilometers north of the Bonn city limits. The starting point is on the banks of the Rhine, just before the ferry dock. The maritime atmosphere tempts you to watch the ships on the Rhine and admire the pretty motor yachts in the harbor basin. To the left of the ferry there is a peninsula, the tip of which is marked out by a beacon - this is where the Sieg flows into the Rhine. The Sieg cycle path runs between the harbor basin and the edge of town, soon passing two branches of the Sieg. A small asphalt road leads towards the Sieg ferry. Shortly before the ferry, you have the choice of cycling through the floodplain landscape to Troisdorf on the right or left of the Sieg; both options are equally good. Although you haven't been in the saddle for long, a rest in the beer garden of the "Zur Siegfähre" restaurant only adds to the cycling experience and so the short detour is highly recommended. It is also possible to cross the Sieg on a ferry here. Constantly following the tops of the dykes on both sides of the river, the view sweeps over the wonderful, wide floodplain landscapes. Along lush meadows, the Sieglarer See is passed, which is a popular breeding ground for water birds. On the outskirts of Troisdorf, the two paths meet at the Sieg Bridge and soon the view falls on the Michaelsberg Abbey, which rises above the town of Siegburg. Here, it is worth taking a detour into the town centre with many places to stop for refreshments and to shop around the market. On the journey to Hennef, just a few kilometres away, the cycle path repeatedly runs close to the river bank. The Hennef train station is passed in the immediate vicinity and after circling the Weldergoven settlement, the cycle path runs close to the railway tracks. At Lauthausen, the Sieg shows its powerful side: the water rushes down a rapid with a roar and offers a lively sight. Around 200 m opposite the Blankenberg stop, the Sieg is crossed in the direction of Oberauel and soon the mighty walls of the Blankenberg castle ruins greet you from a 150 m high mountain ridge. The castle ruins and the town of the same name with its beautiful half-timbered houses and well-preserved town wall form a fascinating historical ensemble and are definitely worth a visit. If you want to enjoy the Sieg cycle path as a two-day tour, the town of Blankenberg is a suitable destination, as it is "halfway" here. The cycle path winds along the Sieg loops and after the small town of Auel is immediately bordered by beautiful deciduous forest and the river. Behind Auel, the railway crossing has a special feature. To open the locked barrier, you press a request button and speak briefly to an employee in the signal box. You then use the same method to let people know that you have passed the crossing. The cycle path continues over two new bicycle bridges directly to the train station and then to Merten Castle, which is well worth seeing. After leaving the town, you first have to overcome a steep climb into the forest. Before you go straight back down to the banks of the Sieg through the settlement of Lützgenauel, the view of Eitorf at the highest point makes up for the effort. The climb can be avoided. Between Merten and Bourauel, the cycle path next to state road 333 can be used for this. Then, on the opposite side of the river, is Eitorf, whose train station can be reached quickly via a bridge to Siegpark. The rest of the route to Dreisel is what you would imagine an ideal river cycle path to be. You roll along the river bank without interruption. Nothing spoils the view of the lush green meadows that stretch along the river loops. On the opposite side of the Sieg, dense mixed forests stretch up the steep mountain slopes and it almost seems as if they form the natural framework for the river scenery. Past Herchen train station, it is another 1.5 km to the town. Here and a little later at the Sieg loop near Röcklingen, the river is crossed twice. After passing the S-Bahn stop on the outskirts of Wilberhofen, the asphalted path runs to Dreisel. From Dreisel, a steep incline of around 70 meters leads up to Maueler Berg. There are two options for the return journey by train: either from the Dattenfeld S-Bahn station in the Wilberhofen district or from the train station in Schladern, around 3 km away. After the rapid descent, it is worth taking a detour to the Sieg waterfall and the impressive castle ruins in Windeck Schladern. The cycle path runs between the river and the road as far as Rosbach, the current end of the Sieg cycle path. In Rosbach, it is possible to take the train back to the starting point. If you want to continue towards the Siegquelle, we recommend using the Deutsche Bahn (RE 9) between Au/Sieg and Mudersbach-Niederschelderhütte.
We recommend this route from Mudersbach/Niederschelderhütte to the Sieg-Quelle.
There are several bike rental stations along the cycle path, mainly at bus and train stops. The rental can start and end at any station and is done via the app (www.nextbike.de/de/rsvg).
