Argentina's hot springs are termas, and at least 6 of them sit in this directory, stretched from the Andes to the eastern river plains. The volcanic mud and mineral pools of Termas de Copahue rise near a Patagonian volcano, while Termas de Cacheuta sits in a canyon outside Mendoza. 4 of the 6 listed here are resort spas, and all of them are paid. Developed termas, not wild pools, define the country.
The Andes and the Cuyo wine country hold Argentina's best-known volcanic and mountain termas. The sulphur mud baths of Termas de Copahue near the Caviahue volcano draw health visitors each summer, while Termas de Cacheuta fills canyon pools in the mountains above Mendoza. Two of the directory's Argentine springs sit along this western mountain spine, both set among peaks and reached on winding roads from the nearest wine towns.
The northwest gathers high-desert termas across Catamarca and Jujuy. Terraced pools climb a mountainside at Termas de Fiambala in Catamarca, while Termas de Reyes fills a green canyon in the hills above San Salvador de Jujuy. Both sit at altitude in the arid Andean northwest, hours from the nearest city, where thermal water has drawn travellers along old mountain routes for generations.
The eastern Litoral, on the warm plains of Entre Rios, holds riverside spa parks fed by deep thermal wells. Family water parks at Parque Termal Federacion and Termas Villa Elisa draw weekend visitors from across the region near the Uruguay River. These lowland termas round out the directory's Argentine entries, and their warm wells and shallow family pools stay busy through the cooler winter months.
Argentine thermal bathing centres on the termas, a paid spa complex with warm pools and an on-site hotel, rather than free wild springs. The volcanic mud baths of the Andes contrast with the deep-well water parks of the eastern plains, giving the country two distinct styles. All 6 springs listed in this directory charge entry, and none is free. Water at the highland sites runs warm to hot before cooling for bathing. These sit within the wider hot springs in South America.
