The Siebengebirge and the Rhine belong together. If you make a boat trip on the Rhine and you come to Bonn-Bad Godesberg on the left bank and Bad Honnef and Königwinter on the right, you have a wonderful view of the Drachenfels and the other mountains. From up there you have a great view over the Rhine Valley. Here are some impressions.
Numerous small and large pleasure boats take you downstream to Bonn, Cologne, Düsseldorf and even across the border to Holland, or upstream through the famous Middle Rhine Valley to Linz, Koblenz, Mainz, Bingen and even further to the Rheingau.
