Source of the Danube and start of the Danube Cycle Path, Donaueschingen

According to common opinion, the Danube is formed a little east of Donaueschingen by the confluence of the two source rivers Brigach and Breg. A well-known motto here is: Brigach and Breg bring the Danube along. However, the source of the Danube is at least two real sources; symbolically those of the Donaubach in Donaueschingen and hydrologically those of the larger source river Breg at the Martin's Chapel near Furtwangen.

The official starting point of the Danube cycle path is at Lammplatz in Donaueschingen.

What gushes out of the earth at the source of the Danube is water from the Black Forest, which has seeped into the earth, flowed underground to the edge of the Black Forest, and re-emerges as the spring in Donaueschingen.
