Situated off the eastern coast of Jeju Island, Udo Island was named because it resembles a lying cow. It boasts fertile soil, abundant schools of fish, and scenic sights; local heritages (female divers, stone walls, and stone tombs) as well as natural attractions abound on the island, making it a miniature of Jeju Island. The island is also full of amenities and tourism outlets: fishing, bike trails, sand massages, submarine tours and cruises.
Seobin Baeksa (a white beach designated Natural Monument No. 438) has appeared regularly in films and TV commercials thanks to its breathtaking white sand and emerald sea. The sea around the beach showcases different colors depending on the water level. This makes Seobin Baeksa one of the most popular tourist attractions in Jeju-do, along with Hallasan Mountain. Standing on Udobong Peak (132.5m), the highest spot on the island, is a lighthouse surrounded by a spacious park. The peak offers outstanding overlooks of the island at a glance.
To protect the exquisite nature and promote maritime tourism, Bukjeju County designated two ports on the island (Udo Port and Haumokdong Port) and the sea surrounding it (25,863㎢) as Udo Maritime Park in January 2001. Visitors can appreciate maritime tourism at its best including a trip under the sea by submarine.
