July 7, 2022,Unsere 5-Flüsse-Tour: Etappe 3: Von Regensburg nach Riedenburg

As with our last multi-day tour, we unfortunately had a rainy day again this year. But we cycled through the tour despite the sometimes heavy continuous rain.

June 24, 2025,Fünf Flüsse Radweg Etappe 3: von Regensburg nach Riedenburg ML

A very beautiful route, almost always along the water. There are several places to stop for refreshments, which are also open on Tuesdays. The route was partly paved, with a larger section covered in fine gravel. But it was all very easy to ride.

August 6, 2025,Riedenburg - Regensburg

In bright sunshine and in a great mood, we completed our last leisurely "Rivers Tour" leg to Regensburg today. Since travel is, as we all know, educational, we now also know what Prunn Castle has to do with the Nibelungenlied (see photo) and why the "Tatzlwurm" wooden bridge is only the second longest in Europe. 😉 Tomorrow we'll take the …

August 9, 2021,11. Sommerradtour 2021 - Von Riedenburg nach Regensburg

The final stage of my summer bike tour initially continued along the Main-Danube Canal / Altmühl. This flows into the Danube in Kehlheim. Here the path became a bit more interesting again, because the river naturally has significantly more currents than a canal and the landscape has changed a bit again. The destination of the stage is Regensburg and since …

The third day started with rain. Further along the Altmühl, the river flowed into the Danube after 20km.
We followed the Danube to Regensburg.
Since it rained continuously and we were so wet and dirty, we cycled the 57km without stopping or stopping for refreshments.
In Regensburg, the Green Spirit Hotel was our destination. We were able to park our …

August 24, 2024,Altmühltal 2024 - in 6 Tagen von Regensburg über Donau, die Altmühl und die Tauber nach Würzburg - Tag 1 - Von Regensburg nach Riedenburg

The 47-year-old diesel horse took us to Regensburg. Then we went along the Danube under muscle power in glorious weather. Just before Kehlheim we had to go for a swim. Then we went along the Altmühl to Riedenburg, our destination for today. There's a folk festival this evening.
