This summer we enjoyed the Donau Radweg a nice bike tour along the Danube river. The tour along the river can be quite long (more than thousand km), but we just did a little part, 7 days trip and 350km, from Passau (Germany) to Vienna (Austria), I would say one of the best bike tour I did ever!
Let me share with you just a lovely places we visited:
Inzell, a tiny village were we overnight the first day, just after this amazing river curve:
Krems, in Wachau is the capital of the white wine. Here we enjoyed to cycle through the wineyards and the white wine!
