The hot springs that give Baños its name (literally "baths") flow from the flanks of Tungurahua at high temperature. Several bathing complexes have been developed around these springs, ranging from the basic public pools at the Complejo de Aguas Termales to more developed spa facilities. The water is dark and sulphurous — not everyone's aesthetic, but with genuine mineral content.
The most popular option is the main public complex adjacent to the Virgen waterfall at the edge of town. Open evenings as well as daytime, the pools are particularly pleasant after dark when the temperature drops. Ecuadorian families use these pools regularly, and they have a genuine community character quite different from spa tourism. Bring a towel and a pair of flip-flops; lockers are available.
