The thermal water in Baden bubbles out of 18 different springs. With 4.6 grams of minerals per liter, it is Switzerland’s most mineral-rich thermal water. Having a temperature of around 47°C, it also belongs to the warmest in the country. The water naturally rises to the surface from depths of up to 1,200 meters and is a source of blissful warmth. It has been stored for between 4,000 and 12,000 years in the bedrock underneath the spa town, which gives it its high mineral content. In addition to calcium, iron and iodine, the “liquid gold” contains sulfur, the mineral which gives the thermal water its distinctive odor. Quantities of methane, fluorine, zinc and magnesium can also be found in the water. Magnesium is essential for maintaining muscle function and stimulating bone formation in the human body.
