Yökö Termales, in Liberia, Guanacaste, Costa Rica, offers sulfurous water at 42°C, pH 6.5. An indoor bath, an outdoor rotenburo-style bath, a sauna, and massage are on offer.
Insider tip — Yoko Termales is a thermal resort in the foothills of Rincon de la Vieja volcano in Guanacaste, offering landscaped geothermal pools fed by the same volcanic system that powers the nearby national park. The sulfurous waters are channeled into comfortable resort pools set amid tropical gardens with guanacaste and palm trees. The dry season from December to April provides clear days ideal for spotting howler monkeys and toucans from the poolside.
