Jeju Island, officially the Jeju Special Autonomous Province, is South Korea's largest island, situated south of the Korean Peninsula in the Korea Strait. It was formed approximately 2 million years ago through significant volcanic activity, with Mount Hallasan rising to 1,950 meters as the nation's highest peak. The island was designated a UNESCO World Natural Heritage site in 2007, specifically for its unique volcanic landforms and extensive lava tube systems. Jeju is famous for its "Haenyeo" female divers who harvest seafood manually without breathing apparatus, representing a distinct matriarchal cultural element. The local economy thrives on international tourism and the specialized cultivation of tangerines, benefiting from a humid subtropical climate. Historically, the isolated island served as a place of exile during the Goryeo and Joseon dynasties and witnessed the tragic Jeju Uprising in 1948. The island is also home to the Manjanggul Cave, which is among the longest lava tube structures globally.
