Salinas del Almiron is a natural thermal and saltwater spring complex in the Salto Department of northwestern Uruguay, where chloride-rich geothermal water from the Guaraní Aquifer is combined with natural salt deposits to create a distinctive saline thermal bathing experience in the rolling Uruguayan grasslands. The site, part of Uruguay's 'Litoral Termal' thermal tourism route, reflects the Guaraní Aquifer's immense mineralogical variety as it surfaces in different compositions across the region. The surrounding Salto Department's estancia landscape, gaucho culture, and the scenic Uruguay River provide a characteristically Uruguayan rural backdrop for this mineral-rich thermal bathing experience.
Insider tip — These thermal springs in the Rio Negro department of Uruguay tap the Guarani Aquifer, one of the world's largest underground freshwater and thermal reservoirs. The warm saline-tinged waters are characteristic of the deep Mesozoic sedimentary formations beneath the Uruguayan plains. The surrounding estancia landscape of rolling grasslands and cattle ranches gives the site a distinctly gaucho atmosphere.
