It's a thermal Spa in a big city. There are very few cities in the world that have a mineral-medicinal water source in the urban area. In Valencia, we are the only ones that can be called urban thermal Spa.
The water flows naturally at 43 degrees Celsius. The predominant minerals are magnesium, copper and zinc, which allows their waters to be a powerful natural analgesic, as well as relaxing and rejuvenating skin.
