Aachquelle – Aachtopf

With an average of around 8,600 liters per second, it is the most abundant source in Germany. The water comes from the Danube infiltration in the north of the Aachtopf and feeds the Radolfzeller Aach, which flows into Lake Constance after about 32 kilometers between Moos and Radolfzell.

For many years, the water power was used for production by the Schiesser companies in Volkertshausen and Rielasingen.

Interesting geology: The Aachquelle originated from the underground drainage of the Danube. Today unfortunately neglected and completely muddy.

The largest spring in Germany in one of the 100 smallest places in Germany: Aach. The source is nothing spectacular. You can hike along, drink coffee in the self-service restaurant. Lay on the bike course. Free entry. Homepage available.

Beer garden absolutely recommendable, but note the opening times: closed from around 1 p.m. on Tuesdays and Fridays. Sausages of all kinds are highly recommended, and the selection of cakes ...
Wednesday is good because Daniela's farm shop in Steißlingen is usually open (it's best to inform in advance).

Very nice refreshment for the feet, just cool down a bit!

Nothing spectacular. But the largest source of Germany in one of the 100 kl. Places of Germany. No entry.

A nice bike ride from the Aachtopf to the confluence with the Untersee near Radolfzell.
