Sanho Beach

Sanho Beach is a beach composed of red algae nodules, formed by the precipitation of calcium carbonate from calcareous red algae inhabiting the waters around Udo. While it was known in the past as a coral sand beach, it is actually a red algae nodule beach designated as Natural Monument No. 438. As one of the eight scenic views of Udo, Sanho Beach is characterized by its white sediments and sea colors that change depending on the water depth.
