Termas del Cañón del Blanco (Vaca) is a naturally sulphurous thermal spring in the White Canyon (Cañón del Blanco) of Chile, the 'Vaca' — Cow — designation indicating a specific pool or section of the canyon's thermal spring system distinguished perhaps by its size, shape, or some bovine association in local naming tradition. The White Canyon thermal springs are known for the striking pale mineral deposits that the siliceous and sulphurous geothermal water leaves on the canyon walls and spring margins, creating a visually dramatic landscape of white mineral formations against the rocky Andean terrain. The spring offers warm, sulphurous mineral water in a scenically extraordinary Chilean volcanic canyon setting.

Insider tip — Termas del Cañón del Blanco (Vaca) occupies a dramatic river canyon in the Araucanía region, where hot sulfurous springs seep directly into the riverbanks and form natural rock pools. The canyon walls amplify the volcanic aroma and create a striking microclimate even in winter. Access requires a short hike along the gorge trail, and water levels vary seasonally so the best pools shift with the river flow. The site rewards explorers who prefer raw nature over developed spa infrastructure.
