At Calistoga Spa Hot Springs, the composition of our
mineral water is deemed by Nature's filtering of rainwater through our alluvial Napa Valley soils resulting in a blend of trace mineral and essential elements. Geothermal forces elevate the temperature of the mineral water to 180 degrees Fahrenheit at the source. The mineral pools at Calistoga Spa Hot Springs consist of four unique pools, each designed to revitalize the senses.
