Termas del Ayui is a natural thermal spring resort in Entre Ríos province, Argentina, located above the Guaraní Aquifer in the Mesopotamia region between the Paraná and Uruguay rivers, where lightly mineral oligomineral geothermal water feeds open-air thermal pools on the rolling Entrerriana pampa. Entre Ríos is one of Argentina's principal thermal spring provinces, and Termas del Ayui represents the province's tradition of unpretentious, nature-oriented thermal tourism amid the subtropical grasslands and palmeras (palm savannahs) of Argentine Mesopotamia. The surrounding Entre Ríos landscape, with its rivers, wildlife, and gaucho heritage, provides an authentically Argentine interior setting for thermal bathing.
