Seobinbaeksa: The Emerald Sanctuary of Udo Island
Nestled along the scenic Olle Trail Course 1-1, Seobinbaeksa is a rare geological marvel in Jeju’s Udo-myeon area. Unlike typical sandy shores, this beach is world-famous for its white “popcorn” sand—unique nodules of calcified red algae that are so rare they are designated as a protected National Monument of Korea.
While the pebble-like texture makes it less ideal for swimming, the visual contrast is stunning. The brilliant white shore meets a vivid gradient of turquoise and cobalt waters, offering a peaceful, less-crowded alternative to Udo’s busier spots. It is the perfect place for a quiet rest or a moment of reflection, where the understated charm and serene coastal views provide a refreshing break for any traveler.

FAQ
What makes the "sand" at Seobinbaeksa unique, and can I take it home?
Unlike regular sand beaches made of crushed shells or quartz, the shore at Seobinbaeksa is composed entirely of rhodoliths—popcorn-shaped nodules of red algae that have calcified and bleached white over time. It is the only beach of its kind in Asia and is designated as a national natural monument. Because of its protected ecological status, it is strictly illegal to collect or take any of the white stones from the beach. Violators can face incredibly heavy fines at the ferry terminal.
How do I get to Seobinbaeksa from Jeju Island?
Because the beach is located on Udo Island (a smaller island just off the eastern coast of Jeju), you must take a ferry to reach it: Ferry Ride: Head to the Seongsan Port Passenger Terminal on Jeju and take a 15-minute ferry to Udo Island (arriving at either Cheonjin Port or Haumokdong Port). Island Transit: Once you land on Udo, Seobinbaeksa is highly accessible. It is located on the western coast, just a 15-to-20-minute walk from Haumokdong Port. Alternatively, you can hop on the island's tourist shuttle bus, rent an electric bicycle, or rent a mini electric car right at the harbor
Is it a good beach for swimming and barefoot walking?
While the water is breathtakingly clear and turns a vibrant, tropical turquoise gradient on sunny days, it is actually not ideal for casual barefoot walking. The pebble-sized rhodolith stones can be quite sharp and uncomfortable to step on with bare feet, so wearing water shoes or thick sandals is highly recommended. The shoreline also drops off relatively quickly into deeper water, so while swimming is permitted during the summer designated beach season, casual waders should watch their step on the slippery stones.
