Balneario Municipal in Fiambalá, Catamarca province, Argentina, draws thermal water at 42°C (108°F). The site offers indoor pools, massage and a sauna, in an Andean village known for its natural hot springs at the foot of the cordillera.
Insider tip — Fiambalá's thermal springs are among Argentina's most spectacular — a series of natural geothermal pools in the Pre-Andes foothills at 1,700m altitude, surrounded by the multicolored Fiambalá dunes (pink, ochre, and white sand). The Dakar Rally has passed through this extraordinary landscape multiple times; at night, the Atacama sky above Fiambalá offers some of the world's finest stargazing. The municipal balneario provides organized access to these pools beloved by Argentine and Chilean travelers.
