Termas de Salto Grande is a thermal resort within the Parque del Lago, adjacent to the massive Salto Grande hydroelectric dam on the Uruguay River, where bicarbonate-rich Guaraní Aquifer geothermal water fills outdoor pools in a lakeside park created by the dam reservoir. The combination of the vast artificial lake — one of South America's largest reservoirs — the engineering marvel of the hydroelectric dam, and the natural geothermal heritage of the Guaraní Aquifer creates a uniquely layered environmental and technological landscape. The reservoir's watersports, fishing, and the park's birdlife complement the thermal bathing experience in this comprehensive Uruguayan nature resort.
Insider tip — Termas de Salto Grande occupies the shores of the Salto Grande reservoir on the Uruguay River, created by the binational Argentina-Uruguay hydroelectric dam of the same name. The thermal complex draws from Guarani Aquifer waters and benefits from a spectacular lakeside setting with the dam infrastructure visible in the distance. Bicarbonate-rich water at comfortable temperatures suits long afternoon soaks. The reservoir attracts migratory waterfowl making it a rewarding spot for birdwatchers between sessions.
