Jeju City
Jeju City is the capital of Jeju Island (제주도) — a volcanic island of 700,000 people 60km off the southern coast of South Korea, separated from the mainland by the Korea Strait, and known internationally as 'Korea's Hawaii'. The island is built on a basalt shield volcano (Hallasan — 한라산, 1,950m, the highest peak in South Korea, a dormant shield volcano with a crater lake (Baengnokdam) at the summit, UNESCO Biosphere Reserve). The island has been shaped entirely by volcanic activity: lava tube caves (Manjanggul — the longest lava tube in Asia at 7.4km, UNESCO), parasitic cinder cones (oreum — 360 volcanic cones distributed across the island), black basalt sea cliffs, and the explosive tuff crater of Seongsan Ilchulbong (성산일출봉 — Sunrise Peak, a UNESCO site that rises 180m from the sea like a natural amphitheatre). The island's distinct cultural identity includes the haenyeo (해녀 — the female free-divers who dive without equipment to 20m to harvest abalone, sea urchin, and conch, a tradition with 1,500 years of documented history, UNESCO Intangible Cultural Heritage 2016), the dol hareubang (돌하르방 — stone grandfather statues, the island's totemic symbol, carved from basalt in a stylised protective figure), and Jeju black pig (흑돼지 — a heritage pig breed with black bristles, considered the finest pork in South Korea). Best months: April–June (canola flower fields) and September–November.
