Termas Colón

Termas Colón in the Entre Ríos Province of northeastern Argentina, part of the celebrated Comunidades Termales de Entre Ríos, draws from the Guaraní Aquifer, one of the world's largest underground freshwater reserves extending beneath the subtropical heartland of South America, whose deep thermal waters emerge at temperatures between 38 and 45°C after long subterranean journeys through geological formations in the Argentine Mesopotamia between the Paraná and Uruguay rivers. The bicarbonate-rich thermal water feeds a well-developed resort complex in the pleasant provincial capital of Colón on the Uruguay River opposite the Uruguayan city of Paysandú, where the sandy beaches of the Entre Ríos riverside, the regional wine culture of the Corrientes and Entre Ríos provinces, and the extraordinary birdlife of the Mesopotamian wetlands provide a rich natural and recreational context for thermal bathing. The Entre Ríos thermal circuit, connecting thirteen thermally endowed cities along the Guaraní Aquifer's productive zone, creates one of South America's most complete and accessible regional thermal tourism networks in a province whose subtropical nature and warm Argentine hospitality define its distinctive character.
