Aach spring

Welcome to Aach spring

Germany's largest spring. Here the water emerges from the Danube seepage points in Tuttlingen/Immendingen/Fridingen and flows via the Radolfzeller Aach into Lake Constance, from there into the Rhine and finally into the North Sea.

The Aachquelle is the largest karst spring in Germany and supplies more than 8,000 liters of water every day. The water from the Aach spring is exceptionally pure and has a constant temperature of 11 degrees Celsius.
The Aach, which rises from the spring, flows through the Black Forest and finally flows into Lake Constance.
