I cannot recommend the route between Sandharlanden and Holzharlanden - far too much traffic

After driving to the Kelheim jetty, I took a boat trip through the Danube Gorge to Weltenburg, which was beautiful to look at, but it was mass tourism.

I then cycled on the path near the banks of the Danube to Eining, which included many pushing and muddy sections. Afterwards, I looked like I had just been pulled out of …

The scenery is very beautiful and the cycle paths are all easy to ride, even when it has rained, apart from a few puddles. The short detour to …

It's done. For the first time, all Franconian Komootler 60+ and friends were out together. Bernd planned a great tour for us from Riedenburg along the Altmühl and the Danube.
