Jeju: Island, Province, Culture and Natural Heritage of South Korea

Geography and natural features

The island is dominated by a central shield volcano and its summit, Hallasan, which rises above surrounding lowlands. Extensive lava flows produced tunnels and caves; some of these lava tubes and other volcanic formations have been recognized for their global geological importance. The coastline features cliffs, beaches and coastal cones formed by volcanic activity, and the island supports a variety of coastal and upland habitats.

History and governance

Jeju has a long local history shaped by maritime trade, independent local customs and incorporation into wider Korean states. Today it is administered as a province with its own elected government and a capital on the island. Its strategic location and unique past have produced cultural practices and social structures that differ from those on the mainland.

Culture, people and language

Local culture on Jeju is notable for several distinct elements: the haenyeo (women freedivers) who traditionally harvested seafood; stone statues known as dol hareubang that function as cultural icons; small-scale tangerine orchards and breeds of native horse. The traditional speech of the island—often called the Jeju language—differs markedly from mainland Korean and has attracted attention from linguists and preservationists.

Economy, tourism and conservation

Tourism is a primary economic driver, with visitors drawn to volcanic landscapes, hiking routes, caves, coastal scenery and cultural experiences. Agriculture (notably citrus fruits) and fisheries remain important. Conservation efforts seek to balance tourism with protection of fragile volcanic features, habitats and cultural heritage.

Notable places and distinctions

• Hallasan mountain, a prominent volcanic peak and hiking destination.
• Extensive lava tubes and volcanic formations recognized for their scientific and scenic value.
• Cultural traditions such as haenyeo diving and dol hareubang stone carvings.
• Coastal viewpoints, hiking trails and local farms producing distinctive citrus fruits.

Jeju continues to be studied and promoted for both its natural importance and its living cultural traditions, making it a focal point for visitors, researchers and conservationists interested in island environments and heritage.
