Termales de Iza sits in the village of Iza, in Boyacá Department on the Colombian altiplano, at an elevation of over 2,500 metres. Boyacá, known for its colonial heritage and dramatic Andean landscapes, is also home to some of Colombia's oldest documented thermal springs — and Iza is among the most historically significant, drawing visitors from the surrounding region for generations.

The water is thermal and bicarbonate in character, emerging at 39 °C with an alkaline pH of 8.0. The combination of warmth and bicarbonate composition gives the water a soft, almost silky quality on the skin. At altitude, where the air is thin and the temperatures can drop sharply after sunset, sliding into a 39 °C pool with an alkaline mineral profile feels like a calculated luxury. The balneario setting, against the backdrop of Boyacá's green hills and colonial stone villages, grounds the experience firmly in the Andean interior.

Insider tip — Iza is one of Colombia's most celebrated thermal spa villages, perched at 2,500 meters in the Eastern Cordillera's high savanna near Sogamoso and the sacred Lake Tota. The mineral-rich thermal waters have been exploited since pre-Hispanic times by the Muisca people, who considered the springs sacred. Today, the village clusters around a handful of balnearios that serve locals and weekend visitors from Bogota, just four hours away. The surrounding altiplano landscape, with its patchwork potato fields and Andean sky, provides a quintessentially Colombian highland ambiance.
