Jeju Island

Located approximately 80 kilometers off the southern coast of the Korean Peninsula, it is defined by a distinct geography, climate, and culture that set it apart from the mainland and have afforded it a degree of political autonomy. While the rest of Korea experiences a temperate climate with harsh winters, Jeju is sub-tropical, characterized by warmer winters, humid summers, and a landscape dominated by black basalt rock and lush vegetation. It is often referred to as the “Hawaii of South Korea” due to its volcanic origins and resort atmosphere.

The island is entirely volcanic in origin, formed by eruptions that began approximately two million years ago. This geological history is responsible for its designation as a UNESCO World Natural Heritage site. The landscape is dominated by Hallasan Mountain, a dormant volcano that rises 1,947 meters in the center of the island, making it the highest peak in South Korea. Surrounding this central peak are over 360 oreum (parasitic cones), which appear as small, grassy hills scattered across the island. And beneath the surface, the island is honeycombed by massive lava tubes, such as the Geomunoreum Lava Tube System, which features spectacular multi-colored carbonate roofs and dark lava walls.

Culturally, Jeju developed in relative isolation from the mainland. For centuries, it was the independent kingdom of Tamna (before being absorbed by the Goryeo Dynasty in the 12th century). This isolation allowed it to develop its own distinct language, Jejueo, which is often unintelligible to mainland Koreans and is now considered a critically endangered language by UNESCO. Its unique cultural identity is most famously symbolized by the Dol Hareubang (Stone Grandfathers). Seen across the island, these basalt statues with bulging eyes and grim expressions serve as guardians against demons and bad luck.

The island is historically known for having Three Abundances (Samda): Wind, Stone, and Women. The abundance of stone is evidenced in the batdam (black stone walls) that demarcate fields and protect crops from the fierce and salty ocean winds. The abundance of women refers to the island’s strong matriarchal tradition, largely driven by the economic power of the Haenyeo divers — women who continue to harvest seafood without breathing equipment.

Today, Jeju is the country’s premier domestic tourist destination, famous for its tangerines (as ubiquitous as oranges on Mallorca), emerald coastal waters, and extensive hiking trails. Yet its core remains deeply rooted in its unique island mythology and culture.
