Water profile
Soothing — neither hot nor cold, perfect balance.
Rich in active gases or metals — a strong mineral character.
Soft water — natural, classic buoyancy.
Near La Unión in the department of Nariño, close to Colombia's southern border with Ecuador, the Mina de Azufre pool takes its name from the sulfur mine whose geological legacy shapes these waters. Nariño sits on the northern reaches of the same volcanic arc that powers Ecuador's famous thermal belt, and the landscape here — Andean valleys, high-altitude moorland, and volcanic rock — shares that kinship visibly.
The natural spring rises at 38 °C with a strongly sulfurous composition and a pH of 6.5, characteristics that deliver a pronounced mineral experience: the distinctive scent of sulfur, a slightly astringent sensation on skin contact, and the penetrating warmth of genuinely geothermally heated water. This is unembellished, elemental bathing — a connection with the volcanic substratum of the Colombian-Ecuadorian Andes that no spa setting can replicate.
