Balneário Termas do Caldas, in Missão Velha, Ceará state, Brazil, offers thermal water at 40°C, pH 7.3. Indoor pools, massages, and a sauna are available to visitors.
Insider tip — Balneario Termas do Caldas sits in the semi-arid Cariri region of Ceara state at approximately 7.4°S, where deep artesian wells tap into geothermally heated water in the Precambrian crystalline basement. The warm thermal water at around 40°C offers a counterintuitive oasis experience in the hot, dry caatinga landscape. Northeast Brazilian thermal spas are less internationally known than their southern counterparts but serve an important role in regional health and leisure tourism. The facility draws visitors from Cariri's urban centers including Juazeiro do Norte.
