Radweg Sieg cycling path

The Sieg is a 146 km-long low mountain river, that has been left in its original condition, running from its source in the Rothaargebirge mountains near Netphen until it joins the Rhine at Niederkassel-Mondorf. The Radweg Sieg cycling path closely follows the route of the river through untouched pasture landscapes, bright meadows and the world of riverbank plants and animals. Over a 60 km section between Windeck and the outfall of the Sieg into the Rhine, the Radweg Sieg cycling path is practically level and traffic-free, partly following the former maintenance track alongside the Sieg.



The Cologne-Siegen railway track (S 12, S 19 and RE 9) runs parallel to the river Sieg. Carriages for transporting bicycles are available.


Important information:
Because of the poor condition of the Radweg Sieg cycling path along the section Landkreis Altenkirchen, Rheinland-Pfalz, until further notice, no family-friendly cycling route is available at this point. The current route mostly runs directly along the heavily-used B 62 trunk route and is highly dangerous.
Users are therefore recommended to take the RE 9 train between Au/Sieg and Mudersbach-Niederschelderhütte.
