Termales Kilometro 42

Termales Kilómetro 42 is a sulfurous hot spring resort in Colombia named after its location at the 42-kilometre marker on a national highway — a pragmatic naming convention that reflects the straightforward way Colombians often identify thermal springs located along mountain roads passing through the Andes. The resort harnesses naturally heated sulfurous geothermal waters from deep volcanic sources in the Andean cordillera, channeling them into bathing pools set within a dramatic mountain landscape of cloud forest and river gorges. Travelers on the mountain highway have long stopped at Termales Kilómetro 42 to soak in the mineral waters, making it a beloved roadside institution that combines Colombian hospitality with the long thermal tradition of Andean hot spring bathing.
