Source and tributaries of the upper Donau river

The Danube rises in the dense forests and farmlands of the Black Forest, just 50 kilometers east of the Rhine river at Breisach, at an elevation of about 1,200 meters. The Rhine/Danube watersheds are separated by a continental divide created by the mountains of the Black Forest: the Rhine flows north to the North Sea while the Danube flows east to the Black Sea.
The historically-recognized source of the Danube river is at the town of Donaueschingen. The Donauquelle (Danube source) monument in the center of town was built in the 19th century around a spring. A plaque on the moument states: Bis Zum Meere 2840 kilometer “To The Sea 2840km”. The water from the spring flows into the Brigach then 1.5 km east to the junction of the Breg and Brigach rivers,which is the end kilometer point of the Danube, counting down to the sea at the Danube Delta in Romania.

However, the residents of the town of Furtwangen and the village of St Martinskapelle, 48 kilometers upstream on the Breg river, consider themselves as residing at the source.

Just meters from the Kolmenhof Hotel-Cafe ( is the spring at the head of the Breg, with a plaque stating:
An dieser quelle beginnt die geograpghieche Langen -Messung der Donau Deutscher Donaulange 647 km

“At this the source of the Danube begins geographic length measurement German Danube length 647 km”

Thousands of photos taken on two trips down the Danube (first trip starting at Calais, France and the second trip from Vlissingen, Netherlands, both all the way to the Black Sea) have been used to create the EuroCanals PhotoNav Guides for the Danube. They include the photos shown on this website.

In full-page format they display the details of landmarks along the route, in a km-by-km sequence. The photos are identified by kilometer post; they include ports, bridges, locks as well as sites worth noting. Examples are described on this page:
