Aguas Termales Urmiri is a thermal resort in the remote high-altitude department of Oruro in western Bolivia, situated at over 3,700 meters on the Altiplano — the vast Andean plateau shared by Bolivia, Peru, and Chile — where bicarbonate thermal waters heated by the volcanic and geothermal activity of the Andes emerge in one of the world's most extreme thermal environments. The thermal springs here have been used by indigenous Aymara and Quechua communities for centuries, integrated into practices rooted in Andean cosmology that regard natural hot springs as gifts of Pachamama, the earth goddess. Despite the challenging altitude and remoteness, Urmiri's thermal waters and the overwhelming silence of the Bolivian altiplano draw travelers seeking a genuinely off-the-beaten-path Andean thermal experience.
Insider tip — Aguas Termales Urmiri sits at roughly 3,800 m on the Bolivian altiplano, making it one of the highest thermal bathing sites in South America. The bicarbonate springs feed small outdoor pools overlooking a broad, windswept plateau where llama herds roam freely. The thin air intensifies the restorative effect of the warm water on the body. Nights here are extraordinarily cold, so bring heavy blankets if you plan to camp nearby.
