Königliche Kristall-Therme, in Seelze, Lower Saxony, offers indoor and outdoor sodium-chloride thermal pools at 34°C. The complex also features a sauna, massage services and a hammam.
Insider tip — The Königliche Kristall-Therme (Royal Crystal Thermal Bath) in Seelze draws on the same ancient Zechstein salt deposits that give Lower Saxony's spa resorts their identity. Just 15 km west of Hannover, this thermal complex is a convenient escape from the city for Lower Saxony's residents. The design evokes the crystalline saline formations deep underground — cave-like pools, salt-saturated water with high buoyancy, and a comprehensive sauna landscape suited to year-round wellness visits.
