Shuinan Cave in Ruifang District ~ Yinyang Sea ~ Unique Geographical Landscape of Golden and Blue Sea Waters

In Shuinandong, Ruifang District, New Taipei City, the Yin Yang Sea, with its golden and azure waters, is a unique geographical landscape in the coastal area of ​​northeastern Taiwan. The nearby Jinguashi Mountain is rich in pyrite, which dissolves into water to form iron hydroxide, which absorbs mud and sand to form yellow-brown suspended matter, creating the beautiful yellow and blue gradient scenery of Yinyang Sea. The color of the seawater in the bay is yellow-brown due to natural minerals, which forms a sharp contrast with the blue seawater in the open sea. It is called the natural color palette.
