Balneário Thermas de Ibirá, in São Paulo State, Brazil, offers bicarbonate thermal water at 38°C, pH 8. Indoor pools, massage and a sauna make it a relaxing inland getaway.
Insider tip — Balneario Thermas de Ibira draws artesian thermal water from the Parana Sedimentary Basin in the northwestern agricultural zone of Sao Paulo state, amid sugarcane fields and citrus orchards. The bicarbonate-rich water rises naturally from Paleozoic sandstone aquifers at comfortable bathing temperatures, and the resort's pools are set within a landscaped park typical of Brazil's interior balneario tradition. The town of Ibira is small and unhurried, making this a genuine local retreat rather than a commercial tourist destination. Weekends draw families from regional cities like Sao Jose do Rio Preto, maintaining a lively but authentic Brazilian atmosphere.
