Jeju Island, off South Korea’s southern coast, is a stunner. It’s a UNESCO World Natural Heritage Site with amazing beaches, forests, and the tallest mountain in South Korea, Hallasan. The island’s got a sweet mix of old and new, from female divers known as haenyeo catching seafood the traditional way, to being a hot spot for tech and entertainment industries. Despite the buzz, Jeju has kept its cool with stuff like thatched-roof houses. So, whether you’re a local or a traveler, Jeju Island’s got something for you.
