Korea's Rare Gem: The Coral Sand Miracle

#hellohalloween
Sanho Beach is perhaps the most unique beach experience in Korea because its "sand" is actually made up of tiny, crushed white and pink coralline algae called rhodoliths (hongjo-dan). This distinct composition gives the beach a stunning, brilliant white color that contrasts dramatically with the vivid turquoise water. It's not just a beautiful sight—the texture underfoot is unlike any other beach, offering a truly exotic and memorable physical experience. This rare coralline beach is the main reason many people make the trip to Udo Island.
