Donauradweg

Donauradweg, or the Danube Cycle Route, is a long-distance cycling route that follows the Danube from its source in the German Black Forest near Donaueschingen to the Danube Delta on the Black Sea in Romania. It is one of Europe’s best-known cycling routes and part of EuroVelo 6.

The route traverses eight countries—Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria and Romania—linking cities such as Ulm, Regensburg, Passau, Linz, Vienna, Bratislava, Budapest, Novi Sad and Belgrade, before continuing to the Danube Delta.

Total distance is about 2,800 kilometers, with variations depending on start/end points and detours. The terrain is mostly flat along the northern Danube, with hills in the upper Danube, in the Wachau and across the Iron Gates between Serbia and Romania.

The Donauradweg is well signposted and largely composed of dedicated cycle paths and quiet roads. Surfaces are mostly paved; towns along the route provide lodging, bike shops and other services. Some sections include river ferries across the Danube.

Along the way it passes through wine regions and several UNESCO-listed areas, including the Wachau Cultural Landscape and Regensburg’s Old Town. It is widely used for recreation, touring and long-distance cycling.

Best cycled in late spring to early autumn. Travelers should check border and visa requirements for non-EU stretches and plan for seasonal service variations in more remote sections.
