Jeju
Korea's volcanic holiday island
An hour's flight south of the mainland, Jeju is Korea's holiday island — a volcanic world of its own, built around the great shield of Hallasan, the country's highest mountain. Its coast runs from black-rock shores and lava tubes to white-sand beaches; its interior climbs through orange groves and tea fields to forest and crater. It is where Koreans come to honeymoon, hike and slow down, and where a distinct island culture — the haenyeo women divers, the squat dol hareubang stone grandfathers, the constant wind — sets it firmly apart from anywhere else in the country.
Entry admin is national, not local. The K-ETA waiver (to 31 December 2026) and the free online e-Arrival Card apply however you reach Korea — there is nothing Jeju-specific to arrange.
The one thing to sort before you fly is a driving permit if you plan to rent a car — see Getting around, below. For the national rules, see South Korea entry requirements.
Jeju radiates from Hallasan volcano at its centre, ringed by a coastal road: Jeju City and the airport on the north coast, Seogwipo and the resort south, the Seongsan sunrise crater and Manjanggul lava tube in the east, and the beaches and tea fields of the west.
Why Jeju is worth the trip
Jeju feels different the moment you land: the light is brighter, the air softer, the horizon all sea and volcano. Everything on the island radiates from Hallasan, the dormant shield volcano at its centre, whose lava built the whole place — the tubes you can walk through underground, the crater peaks along the coast, the black basalt in every wall and harbour. Around it the island divides into a wetter, wooded north and a sunnier, resort south, ringed by a coastal road that is one of Korea's great slow drives.
It is also a genuine change of register from the mainland cities. This is where you come for a sunrise crater rather than a palace, a bowl of black-pork noodles rather than a night market, a walk on a coastal Olle trail rather than a metro ride. Three or four days is enough for the highlights; a week suits anyone who wants to hike Hallasan and take the coast at island pace.
Understanding Jeju: the areas that matter
The island is bigger than a day, and its sights are spread around the ring road rather than clustered in one town. Think of it in five parts.
-
Jeju City & the North
The island's capital and gateway, where the airport, ferry port and most flights land. Busy and workaday rather than pretty, but the practical base for arrivals, food and the western sights.
- Best for
- Arrivals, black-pork dinners, convenience
- As a base
- Handy and well-connected; not scenic
- Reason to add
- Where every trip begins and ends
-
Seogwipo & the South
The sunnier south coast: waterfalls, the Jusangjeolli basalt cliffs, resort hotels and a relaxed harbour town. Warmer and greener than the north, and the nicest place to stay.
- Best for
- Waterfalls, coast, a resort base
- As a base
- The most pleasant place to sleep
- Reason to add
- Jeju at its most scenic
-
The East
The island's headline scenery: the Seongsan Ilchulbong sunrise crater, the Manjanggul lava tube, the tiny island of Udo and the coastal walks around Seopjikoji.
- Best for
- The signature sights and sunrises
- As a base
- Better as a full day than a base
- Reason to add
- The must-see corner of Jeju
-
The West
Long white-sand beaches such as Hyeopjae, the O'sulloc tea fields and green-tea museum, and quieter fishing villages — the gentler, beachy side of the island.
- Best for
- Beaches, tea fields, easy days
- As a base
- Good for a beach-focused stay
- Reason to add
- The island's best sand
-
Hallasan & the Interior
The volcanic heart: Hallasan National Park, its summit crater lake, forest trails and the oreum parasitic cones that dot the uplands. Cooler, wilder and often mist-wrapped.
- Best for
- Hiking and volcanic landscape
- As a base
- A day trip from the coast, not a base
- Reason to add
- The mountain that made the island
Start planning: four decisions
A Jeju trip comes down to a few early choices.
- Give it three or four days. Two feels rushed on an island this spread out; three or four let you take the east, the south coast and either a beach or Hallasan without racing the ring road.
- Car or bus — decide before you fly. A rental car roughly halves your travel time and reaches everything; if you want one, you must bring a physical International Driving Permit from home (see below). Without a car, the revamped express buses cover the main sights perfectly well.
- Base south, or split. Seogwipo and the south coast are the most scenic base; many split a trip between Jeju City (north) on arrival and Seogwipo (south) for the rest.
- Mind the season and the wind. Spring (canola and cherry blossom) and autumn are ideal; summer is hot, wet and the peak; winter is mild but blustery, with camellias and snow on Hallasan. Jeju is windy year-round — it shapes the days more than the temperature.
Places you don't want to miss
Jeju's highlights are overwhelmingly natural — craters, caves, coast and mountain. A selection, chosen to be different from one another rather than ranked.
-
Jeju's signature sightSeongsan Ilchulbong (Sunrise Peak)
A vast tuff crater risen straight from the sea, its rim a short steep climb for the classic Jeju view — famously at dawn. A UNESCO World Heritage site, and the image most people carry of the island.
-
The mountain at the centreHallasan
South Korea's highest peak and the volcano that built the island, with a crater lake at the summit and day-hike trails through changing forest. A full but achievable day for fit walkers; check trail and reservation rules first.
-
Underground JejuManjanggul Lava Tube
One of the world's finest lava tubes, part of the UNESCO-listed volcanic system — a cool, cathedral-like passage you can walk deep into, past lava columns and flow lines. A striking counterpoint to all the coast and sky.
-
An island off the islandUdo
A short ferry hop off the east coast to a tiny, flat island of stone walls, peanut fields and quiet beaches — easily circled by bike or scooter in a half-day, and a lovely change of pace.
-
The scenic southSeogwipo's waterfalls & coast
The south coast around Seogwipo strings together the Cheonjiyeon and Jeongbang waterfalls (the latter dropping straight into the sea) and the hexagonal Jusangjeolli basalt cliffs — an easy, rewarding day on foot.
-
Living island cultureThe haenyeo & the Olle trails
Jeju's haenyeo — the free-diving women who harvest the seabed, a UNESCO-recognised tradition — still work the coast; watch for them near Seongsan. The waymarked Olle walking trails link it all along the shore.
Getting there and around
Getting to Jeju
Almost everyone flies. The Seoul–Jeju air route is one of the busiest in the world, with departures every 15–30 minutes from Gimpo and a flight time of about an hour and a quarter into Jeju International Airport (CJU), a short drive from Jeju City. Busan and other mainland cities also connect directly. There is no direct ferry from Seoul; the sea route means a train or bus to Mokpo or Wando and a ferry across (roughly 1–4.5 hours depending on the vessel) — slower, but an option with a car or a fear of flying.
| From | Mode | Time | Notes |
|---|---|---|---|
| Seoul (Gimpo) | Flight | ~1h 15m | Departures every 15–30 min; many airlines |
| Busan | Flight | ~1h | Frequent direct services |
| Mokpo / Wando | Ferry | ~1–4.5h | No direct Seoul ferry; reach the port first |
Getting around the island
Jeju has no train or metro, so it's a choice between renting a car and using the buses. A rental car roughly halves travel times and unlocks the coast and interior — but to drive you must carry a physical International Driving Permit alongside your home licence and passport. Crucially, the IDP must be issued in your own country before you travel; you cannot obtain a valid one after landing, and digital copies are not accepted. Without a car, Jeju's revamped bus network works well: red express buses link the airport to Seogwipo, Seongsan and the main hubs for a couple of thousand won, and all buses now take contactless cards. Use KakaoMap or Naver Map to navigate (Google Maps barely works), and Kakao T to hail taxis. For the national picture, see Getting around South Korea.
If you intend to drive, sort the IDP at home first. It's the one piece of Jeju admin that can't be fixed on arrival — and rental disputes over pre-existing scratches are common, so photograph the car thoroughly at pickup.
Where to stay, cost and timing
The south coast around Seogwipo is the most scenic base; Jeju City is the convenient one near the airport, and the west suits a beach-focused stay. Many visitors split north and south. Jeju runs a little pricier than the mainland at peak times — it is Korea's main domestic holiday spot — so book well ahead for summer, and for spring and autumn weekends.

A few myths (and realities)
- Myth: Jeju is just a honeymoon resort. Reality: Honeymooners come, but so do hikers, families and walkers — the island is really about volcanic landscape, coast and the outdoors, at any budget.
- Myth: you can't see Jeju without a car. Reality: A car is easiest, but the revamped express buses reach all the main sights; plenty of visitors do Jeju car-free with a bit more planning.
- Myth: it's a tropical island. Reality: Jeju is mild and green, not tropical — warmer than the mainland, but with real seasons, persistent wind, and snow on Hallasan in winter.

Visiting Jeju: FAQs
How do you get to Jeju Island?
Almost everyone flies: the Seoul–Jeju route is one of the world's busiest, with departures every 15–30 minutes from Gimpo and a flight of about an hour and a quarter into Jeju International Airport. Busan and other cities connect directly too. There is no direct ferry from Seoul — the sea route runs from Mokpo or Wando after a train or bus to the port.
How many days do you need in Jeju?
Three to four days suit most visitors, given how spread out the island is. That covers the eastern sights (Seongsan Ilchulbong, Manjanggul, Udo), the scenic south coast around Seogwipo, and either a beach day in the west or a Hallasan hike. A week suits keen walkers.
Do you need a car in Jeju?
Not essential, but it helps: a rental car roughly halves travel times and reaches the whole ring road and interior. To drive you must bring a physical International Driving Permit issued in your home country before you travel — you can't get one after landing. Without a car, the revamped red express buses cover the main sights well.
When is the best time to visit Jeju?
Spring (April–June), for canola and cherry blossom and mild weather, and autumn (September–October), for clear skies, are the best windows. Summer is hot, wet and the domestic peak; winter is mild but very windy, with camellias in bloom and snow on Hallasan.
Is Jeju worth visiting?
If you want nature and a change from the mainland cities, yes: volcanic craters and lava tubes, a dramatic coast, Korea's highest mountain and a distinct island culture of women divers and stone grandfathers. It is Korea's holiday island for good reason, though its appeal is scenery and the outdoors rather than urban sights.
