Tambo Hot Springs, near Macari in the Puno region of Peru, on the high Andean plateau, offers bicarbonate thermal water at 37°C. It is enjoyed in a natural open-air pool under the sky.
Insider tip — Tambo Hot Springs emerge in the Macari valley of Puno Region near Melgar province, at approximately 4,000 meters on the high Altiplano where temperatures can drop below zero at night even in summer. The contrast between the icy Andean air and the warm bicarbonate pool water is a visceral highlight of a visit, with steam rising dramatically at dawn over the puna grasslands. Herds of alpacas and vicunas frequently graze nearby, their wool glowing in the high-altitude light, providing an unforgettable tableau. The remoteness requires a 4WD vehicle and local guidance but rewards with absolute solitude.
