Jeju Island South Korea

The haenyeo are Jeju’s female free-divers who harvest abalone, sea urchin, and other seafood from the ocean floor without equipment. The average age of active haenyeo is well over 60. They have been diving to depths of 15 metres in cold water, year-round, for several thousand years. The tradition is on UNESCO’s Intangible Cultural Heritage list. Watching them work in the waters around Seongsan Ilchulbong at morning low tide is one of the more specific cultural experiences on a Korean itinerary, and most package tours don’t include it.

Hallasan

The dormant shield volcano at the island’s centre rises to 1,947 metres, the highest point in South Korea. Two main trails: the Gwaneumsa Trail from the north (8.7 km one way, steep final section, four to five hours up) and the Seongpanak from the east (9.6 km one way, more gradual). The summit crater Baekrok Lake requires a permit from visithalla.jeju.go.kr. Both trails close in the afternoon; start early. In late October and November, the maple and oak forests on the Gwaneumsa Trail turn orange and red, making the approach as good as the summit.

Seongsan Ilchulbong

The UNESCO tuff cone on the eastern tip rose from an underwater eruption about 5,000 years ago. Entry KRW 2,000. Summit trail 1.5 km, 45 minutes return, views into the crater bowl and across the strait. Get there before 8am; after that, tour groups from Jeju City arrive in numbers. The haenyeo demonstrate below; times depend on tides and are posted at the site.

Manjanggul Lava Tube

A UNESCO-listed tube 13.4 km long; 1 km open to visitors. The tube was formed when the outer surface of a lava flow hardened while molten rock continued flowing, leaving an empty tunnel up to 30 metres wide. Constant 11 degrees Celsius year-round: bring a jacket regardless of surface weather. Entry KRW 4,000.

Where to Eat

Jeju black pork is the genuine local speciality. The Heuk Dwaeji district near Jeju City has a concentration of black pork restaurants; order samgyeopsal (grilled pork belly) from the island’s indigenous breed, not the mainland substitute. Around KRW 15,000 to 20,000 per person. Abalone porridge (jeonbok juk) near Seongsan runs around KRW 20,000 to 25,000 and is a distinct meal worth having.

Getting Around

Rent a car from the airport. Jeju’s bus network exists but most worthwhile sites are not well-served. KRW 40,000 to 70,000 per day; roads are good and traffic outside Jeju City is light. The island is 73 km east to west, so site-to-site driving takes 45 minutes to an hour.

Practical Notes

Jeju is visa-free for most nationalities under separate arrangements from the mainland Korean scheme; check your specific situation. Citrus season is October through January; Jeju hallabong mandarins are widely sold. Typhoon season is July through September. The wind is persistent year-round on exposed coasts.
