I've been planning this trip for years. Making the journey from the Alps to Slovakia by bike was a dream of mine 15 years ago.
From Livigno via Offenpass to Umbrail Pass and Stelvio. I have 14 km on the bike and 1300 vertical. Stelvio Alps to Slovakia by bike.
The road along the Danube is mostly flat, sometimes boring. We walk the main routes Passau Linz, Melk to Vienna. Alps to Slovakia by bike.
