Jeju-do (제주도) sits off Korea’s southern tip and feels like a different world from the mainland. The island is dominated by Hallasan — a dormant volcano and Korea’s highest peak at 1,950m — and shaped by millions of years of volcanic activity into a landscape of extraordinary beauty.
Think dramatic lava tube caves, pristine beaches ranging from white to black to red sand, dense forests, crashing waterfalls, and a coastline dotted with haenyeo (free-diving women) bringing up abalone and sea urchins from the cold water. Jeju was designated a UNESCO World Natural Heritage Site in 2007, and once you visit, you’ll understand why.
Getting to Jeju
The island is connected to the mainland only by air and ferry.
By Air: The most popular option. Jeju International Airport (CJU) has domestic flights from Seoul Gimpo (~1 hour, ₩60,000–140,000 one-way), Seoul Incheon, Busan, and other major cities. Book ahead — Jeju routes are among the world’s busiest.
By Ferry: Several services from Mokpo, Wando, and other ports. The Mokpo–Jeju ferry takes about 5 hours; a good overnight option if you want to bring a car.
Getting Around Jeju
Jeju’s sights are spread widely across the island. Renting a car is strongly recommended — the island is very driveable and parking is easy. International visitors need an international driving permit. Car rentals from ₩40,000/day.
Alternatively, intercity buses cover most tourist areas, though waiting times can be long. Taxis are available but can be expensive for cross-island trips.
Key Sights
Hallasan National Park
Hiking Hallasan is the definitive Jeju experience. The Eorimok Trail (6.8km return) is the most accessible route, ending at a scenic ridge. The Seongpanak Trail (19.4km return) goes all the way to the summit crater lake, Baekroktam — one of Korea’s most breathtaking views on a clear day. Start early; trails close at specific times.
Jeongbang Waterfall (정방폭포)
One of the only waterfalls in East Asia that falls directly into the sea. The 23m cascade is stunning, especially after heavy rain.
Manjanggul Lava Tube (만장굴)
One of the world’s longest lava tube cave systems at 13.4km. The publicly accessible 1km section is otherworldly — a cathedral of cooled lava with strange formations including the world’s largest lava column.
Seongsan Ilchulbong (성산일출봉)
A UNESCO World Heritage tuff cone rising 180m above the sea. The sunrise view from the top is spectacular — hence the name, which translates to “Sunrise Peak.” A 20-minute climb rewards with sweeping views of the coast and, on clear days, toward the mainland.
Udo Island (우도)
A small island just off Jeju’s eastern tip, accessible by 15-minute ferry. Famous for peanut ice cream, electric bike riding, and turquoise shallows at Hongjo Beach — some of the clearest water you’ll find in Korea.
Seopjikoji (섭지코지)
A scenic cape on the east coast with wild coastal walking trails, canola fields in spring, and dramatic sea-cliff views. Featured in K-dramas and films — always atmospheric.
Jeju Food Specialties
Jeju has distinct regional cuisine worth seeking out:
- Heukdwaeji (흑돼지) — Jeju black pork. Fattier, richer, and more flavourful than regular samgyeopsal. The strip of restaurants near Black Pork Street in Jeju City is the place to try it.
- Haenyeo Cuisine — Raw and cooked seafood prepared in the tradition of the free-diving haenyeo women: abalone porridge (전복죽), sea urchin (성게), and fresh conch.
- Hallabong (한라봉) — Jeju’s famous tangerine; sweeter and easier to peel than regular mandarins. Buy bags to take home.
- Omegitteok — A traditional rice cake made from omegi grain, unique to Jeju.
Haenyeo: Jeju’s Free-Diving Women
The haenyeo (해녀) are Jeju’s iconic free-diving women, who harvest seafood from the ocean depths without breathing equipment. Recognized as UNESCO Intangible Cultural Heritage, their tradition is centuries old. You can watch them at work at Samseonghyeol area or at designated haenyeo villages on the coast, and taste their catch at seaside restaurants.
Practical Tips
- Driving: Jeju drives on the right. Roads are well-signposted in Korean and English.
- Best time: Spring (canola flowers, March–April) and autumn (October–November) are outstanding. Summer is crowded and warm. Winter sees Hallasan capped in snow.
- Accommodation: Jeju City has the widest choice. Consider staying in the countryside (Seogwipo area) for a quieter base near the southern sights.
- Nature fee: Some sites (Hallasan, Manjanggul) charge small entry fees (₩1,000–3,000).
- Wind: Jeju is known as “the island of wind.” Pack a light jacket even in summer.
Jeju works well as a 3-day add-on to a Korea mainland trip, or as a week-long nature retreat in its own right.
