Once past the famous Bridge at Remagen, the tour sets off downriver. The Rhine promenade offers panoramic views of the Siebengebirge hills and an expanse of mixed forests. The path then leads past Mount Drachenfels near Königswinter to Bonn. As you come round the huge Rhine loop you can glimpse the spires of Cologne Cathedral in the distance. With the Rhine still at your side, you continue downriver and past Cologne harbour to the well-preserved fortress town of Zons. Passing through nature conservation areas, the final stage of the trail ends in the Roman Limes town of Neuss. Terrain: this is a mainly flat, family-oriented route which passes through a number of villages and cities as it tracks the Rhine. The route is mostly on asphalt, with traffic-free paths. Scenery: typical features of the Rhineland scenery include riverside forests and green dykes, Rhine islands and hilltop castles overlooking the river. Almost continuous views of Europe's busiest waterway.
