Termas de Rosario de la Frontera is a historic thermal resort in the subtropical valley of Rosario de la Frontera in Salta province, northwestern Argentina, where sulphurous and bicarbonated springs at 35 to 45 degrees Celsius have been appreciated for thermal bathing since the late nineteenth century when the Argentine state railway provided access to a destination that became the leading thermal resort of the Andes foothills. The Grand Hotel Termas, built in the early twentieth century in a Belle Epoque neoclassical style whose colonnaded facade and formal gardens reflect the confident architectural ambitions of the Argentine oligarchy during the wheat and beef export boom, remains the symbolic heart of a resort whose genteel atmosphere and mineral waters draw visitors seeking a classic South American spa experience. The landscape of cloud forest, sugar cane, and the Andes foothills surrounding the springs creates one of the most scenically distinctive settings of any Argentine thermal destination, and the proximity to the colonial city of Salta and the dramatic Quebrada de Humahuaca adds cultural depth to any visit.
