Bad Buchau, on the shore of Lake Feder, earned its spa-town status through a story told in two chapters. The first peat-bath experiments date back to 1920, followed in 1949 by a municipal bathing facility and in 1951 by the founding of the Moorheilbad Buchau. In 1982 a borehole struck thermal water at a depth of 795 meters and 47.5°C, leading to the opening of the Adelindis-Therme in November 1985, with over 800 square meters of water surface.
Just steps from the baths, the Federseemuseum brings Upper Swabia's prehistory to life: its exhibits and open-air archaeological park reconstruct the world of Ice Age hunters, pile-dwelling lake communities, and Celts, drawing on finds remarkably preserved for 15,000 years in the moist peat soil of the Federsee moor.
Insider tip — Bad Buchau sits on a peninsula jutting into the Federsee, a shallow lake and one of Germany's most important wetland nature reserves in upper Swabia. Its bicarbonate-iodide water, emerging at depth, feeds the Federseepark Therme used for balneotherapy and iodine-rich immersion therapy particularly recommended for thyroid and metabolic conditions. The Federsee lake, with its wooden boardwalk through ancient peatbog, is a UNESCO-recognized Bronze Age archaeological landscape worth exploring between sessions.
