Any recommendations that we must see on the route? Slight detours are ok :)

Hi y'all!

My brother and I will be bikepacking this route from Basel > Zagreb in late July. It's going to be our longest ride to date but we have done 1000kms before so no issues on the endurance side, preparedness, etc., although I'm a firm believer that you learn something new every time and can't be prepared for everything but you can continue perfecting this craft 😎

We are basically following the Danube route from its source and continuing towards Budapest and then doing a sharp right towards Zagreb. We'll mostly stay at campsites (possibly some wildcamping) and warmshowers, if we find any. Plus, we have family and friends along the route so we'll stay with them as well.

I know a lot of folks have done sections of this route so looking for any advice on must-see places. It's okay if we have to deviate slightly from the route but we do have a timeline of about 2 weeks to get this done. ⚡

Much appreciated! 🫡
