Roadbook
This route starts at the train station in Radolfzell on Lake Constance and runs on the bike path parallel to the B 33 towards Konstanz. On the way, you cycle through Markelfingen and Allensbach. Instead of big climbs, you can expect relaxed views of the Untersee. Shortly after Allensbach, you pass by Hegne Castle. Finally, arriving in Konstanz, you cross the new Rhine bridge to the border crossing Gottlieben (CH). Shortly after customs, a beautiful lakeside path leads to Ermatingen. Modernly constructed bike paths take you over Berlingen and Steckborn to Stein am Rhein. For the return trip, two options are available. Either via the Höri peninsula (Wangen – Gaienhofen – Moos) or towards Singen around the Schienerberg (Ramsen – Wiesholz – Bohlingen – Moos), back to Radolfzell.
