The La Laja thermal baths, in Argentina's San Juan Province, combine sulfurous and bicarbonate water at 38°C. Indoor pools, massage and a sauna offer relaxation at the foot of the Andes.
Insider tip — Baños Termales La Laja emerges from the pre-Cordilleran foothills of San Juan province at around 1,500 m, in an arid landscape of quebradas and desert scrub typical of the Argentine cuyo region. The mixed sulfurous-bicarbonate composition reflects waters passing through both volcanic and sedimentary formations before surfacing. The El Nihuil reservoir area nearby adds to the scenic appeal of this dry-country thermal oasis. Water temperatures here vary by pool, so explorers can choose between hotter primary vents and cooler downstream channels.
