Danube Bike Trail 1. - Donaueschingen - Passau - Duna kerékpáros atlasz 1.
The Danube cycling route between Donaueschingen and Passau is about 600 kilometers in length, not including about 260 kilometers of alternative routes and excursions.
Most of the route follows quiet country lanes or dedicated cycling paths. Sections with heavier traffic are rare and usually short. With only a few exceptions, the roads and paths have a hard surface. Gravel sections are usually in good condition. Because the route follows the course of the river, it is almost completely flat. It is mostly on the excursions into the surrounding countryside that must expect some steep sections. It is possible that during flooding part of the route is unusable or closed and you need to use alternative routes.
