The Danube cycle path from Vienna to Budapest is the continuation of the popular bike trail in Europe. Something adventurous but equally interesting, it goes through Austria, Slovakia and Hungary, by extensive lowland forests, friendly Hungarian villages, culturally interesting cities. The scenic Danube Bend, and of course Budapest is the stunning conclusion.
From Vienna to Budapest, length 340 km
