El Danubio en bicicleta

Last summer we did the Danube by bike and it was a wonderful experience and it does not take a expert cyclists to do it. A little training before going is good enough. The roads are quite flat and are well signposted. There are some hills but they are not very long, as soon as you have scaled the hills, you can recover on the downsides..... Children who will find it a great adventure.
