Hallyeosudo Marine National Park is South Korea’s first designated marine national park, known for its stunning coastal archipelago, rich marine biodiversity, and popular outdoor activities such as boating, diving, and hiking across islands.
Established in 1981, Hallyeosudo Marine National Park is located along the southern coast of South Korea, primarily within South Jeolla Province. It encompasses a vast and intricate seascape of over 1,700 islands and islets scattered across approximately 545 square kilometers of ocean and coastal waters. The park's name, 'Hallyeosudo,' translates to 'Navigable Sea Passage,' reflecting its historical significance as a maritime route and its unique geography characterized by rocky shores, sandy beaches, and lush forested islands. The park harbors diverse marine ecosystems, including vibrant coral communities, kelp forests, plentiful shellfish, and a variety of fish species. It also serves as a habitat for marine mammals like finless porpoises. The terrestrial flora is marked by subtropical species and pine forests, providing shelter and breeding grounds for migratory birds. Visitors to Hallyeosudo Marine National Park enjoy numerous recreational opportunities, from kayaking and snorkeling to island hopping by boat. Trails on larger islands, such as Namhae Island and Geojedo’s connected islets, offer scenic views of the ocean and rocky cliffs. The park is also culturally significant, featuring historic fishing villages and traditional lighthouses. Its blend of marine beauty and coastal heritage makes it a prime destination for eco-tourism, marine research, and nature lovers. The park's management focuses on balancing tourism with conservation efforts to protect its delicate ecosystems and promote sustainable visitation.
