Norderney has been a therapeutic sea resort since 1797, and the tradition of Thalassotherapie — using seawater, seaweed, and sea air in health treatments — continues at the island's main spa complex near the Conversationshaus. The facility includes indoor seawater pools, saunas, treatments using North Sea brine, and the full range of German Kurort services.
Day entry to the pools and saunas is available without a treatment booking. For a longer visit, packages combining accommodation with daily spa treatments represent the traditional German way to experience Norderney — a proper health cure of a week or more, as the island's 19th-century visitors intended.
