The story of Therme Eins begins, as is often the case in Bavaria, with a failed oil hunt: in 1938, prospectors searching for petroleum near Bad Füssing, in the Passau district, struck an unexpected mineral spring at roughly 1,000 metres underground. It was American soldiers, in 1947, who improvised the first makeshift baths for their veterans, turning simple concreted drainage pipes upside down.

That improvised beginning eventually grew into Bad Füssing's original bathing facility, today known as Therme Eins, which now offers twelve pools at staggered temperatures, a steam bath and a health centre. The sulphurous, slightly acidic water feeding them has since built the reputation of the whole Passauer Land thermal spa region in Bavaria.

Insider tip — Therme eins sits at the confluence of three rivers in Passau, the baroque city where the Danube, Inn, and Ilz meet on the Austrian border. The thermal mineral waters sourced from Bavarian salt formations provide a warming counterpoint to the region's cold winters. The panoramic glass-fronted pools offer views toward the old town's cathedral spires. After a session, explore Passau's medieval alleyways and sample the city's traditional Bavarian hospitality.
