Water profile
Stimulating — wakes the body and boosts circulation.
Loaded with major ions — the essential minerals (Ca, Mg).
Dense, salty water — you float without effort.
Bad Karlshafen owes its spa-town destiny to Landgrave Karl of Hesse, who set out in 1699 to turn this Weser river port into a bathing resort. The local brine, used as a wellness water since 1838, is now drawn from a 1,150-metre-deep borehole and carries a natural salt content of 23 percent — among the highest in all of Hesse.
Opened in 2004 in a style inspired by southern France, the Weser-Therme offers several saline pools at varying concentrations, including an intensive 12-percent pool reminiscent of Dead Sea buoyancy. A generous sauna area rounds out the complex, set within Hesse's northernmost baroque town.
