Walk out of Jeju International Airport arrivals and three things are happening at once. Rental car shuttles pull up on one side. Limousine buses load on the other. Taxis queue in between.
Most first-time visitors stand there longer than they need to, because they are trying to answer the question with a personality — am I a rental car person or a bus person? That is the wrong question. The right one is what your actual itinerary requires, and it has a clear answer.
Flying In — Including From Somewhere That Isn't Seoul
Jeju sits about 85 kilometres off Korea's southern coast. No bridge, no tunnel. Ferries run, but almost everyone flies.
The Gimpo–Jeju corridor is not merely busy. According to OAG's scheduled-capacity data, Jeju (CJU) to Seoul Gimpo (GMP) is the busiest airline route in the world — over 1.17 million scheduled seats in August 2026 alone, ahead of Sapporo–Tokyo in second place.
That volume is why fares stay low and why you can usually find a seat at short notice.
What travel guides tend to miss is that you do not have to start in Seoul. Direct flights to Jeju run from Busan (Gimhae, about an hour), Daegu, Gwangju, and Cheongju. If your Korea itinerary begins in a regional city, there is no reason to backtrack to Seoul for the flight.
Incheon also flies to Jeju, with far fewer daily departures than Gimpo. If you are arriving internationally and connecting the same day, check whether your carrier offers the connection at Incheon before assuming you need the transfer across the city to Gimpo.
On booking: roughly six weeks out tends to catch the best average fares, with Tuesday and Wednesday departures running cheaper than weekend ones. Compare on Google Flights or Skyscanner, then book direct with the carrier — low-cost airlines frequently undercut the aggregators on their own sites.
The Arrivals Hall: Three Doors
Jeju's airport is compact and single-terminal, pressed against the northern edge of Jeju City. Baggage carousel to kerb is about ten minutes on a normal day.
Then the three options. Here is the short version of what follows, so you can decide before you read the detail.
| Your trip | What to do at the kerb |
|---|---|
| Solo or a pair, 2–3 nights, mostly Jeju City and Seogwipo | Bus, plus taxis as needed |
| Group, 4+ nights, several oreum or an early Hallasan start | Rental car |
| Mostly city-based, one or two hard-to-reach places | Bus, then add a single day's rental |
| Landing after 22:20 | Taxi — Bus 600 has finished for the night |
| Dinner with drinks planned | Taxi that evening, whatever else you booked |
Renting a Car
Jeju is the most natural place in Korea to drive yourself. Dozens of agencies operate near the airport, each running a free shuttle from arrivals to its lot. Roads are signed bilingually, and both Google Maps and Naver Map work across the island.
Daily rates average somewhere around 40,000 won, though that number moves a long way with vehicle class and season. A compact in the shoulder season sits well below it; an SUV in August sits well above. Book ahead in summer — the popular models genuinely sell out.
Electric rentals are widely available and the island's charging network is dense enough that an EV here is a practical choice rather than an experiment.
For comparing operators, the Korean platform 돌하루팡 (dolharupang.com) aggregates the largest number of local companies; 제주패스 (jejupass.com) is the other commonly used one. Rentalcars.com connects to several Jeju agencies if you would rather stay in a familiar interface.
One warning that matters more than everything else on this page. Korea recognises only the International Driving Permit issued under the 1949 Geneva Convention. If yours was issued under the 1968 Vienna Convention — as it is in Germany, France, and several other countries — rental desks will refuse it.
Bring all three documents: the IDP, your original home licence, and your passport. People are turned away at Jeju counters over this every week.
The honest downsides of driving: parking at Seongsan Ilchulbong and the Hallasan trailheads fills early on weekends, and any evening involving drinks means a taxi regardless. On a two-night trip, the pickup and return can eat more time than the car saves.
The Two Roads Over the Middle
Most visitors circle Jeju on the coastal ring and never cross it. Two roads climb over the island's shoulder instead, and both are faster than going around.
1100 도로 (the 1100 Road) passes west of Hallasan and tops out at a rest stop at 1,100 metres — the number is the altitude, not a route code. 516 도로 (the 516 Road) crosses on the eastern side through a long tunnel of overhanging trees that is one of the better drives in the country.
Either one gets you from Jeju City to Seogwipo in under an hour, and both are considerably more interesting than the motorway-style alternative.
Two cautions. Cloud sits on these roads regularly, and visibility can drop to almost nothing within a few hundred metres of climbing — the coast can be in full sun while the pass is in fog. And in winter, snow closes them or restricts them to vehicles with chains, sometimes at short notice.
Check conditions before committing to a crossing in December through February. If they are shut, the coastal road is always open.
Taxis, and When You Will Actually Need One
Taxis are straightforward in Jeju City and Seogwipo, and both Kakao T and the international-facing k.ride app work on the island.
Outside those two towns, availability drops off sharply after dark. A rural oreum car park at nine in the evening is not somewhere a taxi is idling — you will be booking one and waiting.
The practical habit is to save the number of a local call-taxi firm wherever you are staying, and to think about the return leg before you set out for anywhere inland in the evening.
Budget roughly 60,000 won a day if taxis are doing the heavy lifting across the island, and considerably less if you are staying within one region.
The Option Nobody Mentions: Cycling
Jeju has a dedicated island-circuit cycle route, 제주환상자전거길, running about 234 kilometres around the coast on a mix of separated path and marked road shoulder.
It comes with a certification passport and stamp booths at checkpoints along the way, which is a small thing that turns out to be surprisingly motivating.
Most riders take three to five days. Bicycles can be hired in Jeju City and near the airport, and the terrain on the coastal loop is gentler than the volcano in the middle suggests.
It is not a way to see the inland half of the island. As a way to see the coast, nothing else comes close.
The Bus Network Is Better Than Its Reputation
Ask a Korean whether you can do Jeju by bus and you will often get a sceptical look. That reputation is about a decade out of date.
A large-scale route restructuring in 2017 rebuilt the network around three tiers: 간선 (ganseon, trunk routes), 지선 (jiseon, local branch routes), and 급행 (geuphaeng, express services). Coverage of the main coastal destinations improved substantially and has not gone backwards since.
Two things international visitors need to know before boarding.
First, Jeju's city buses are cashless. Since 2024 they have accepted transit cards only — T-money or Cashbee, both sold at any convenience store including at the airport. Load one before you leave arrivals. A card also gets you transfer discounts between routes.
Second, a fare increase has been proposed and repeatedly deferred. The figures below are the current ones, but check the reader as you board.
| Service | Fare | How it works |
|---|---|---|
| 간선 · 지선 (trunk and branch) | 1,200 won | Flat rate |
| 급행 (express) | 2,000–3,000 won | Rises with distance |
| 공항 리무진 600 (airport limousine) | 1,300–5,500 won | By section; full run to Seogwipo is the top band |
| Payment | Card only | T-money or Cashbee — no cash |
Bus 600, and the Two Routes That Circle the Island
Limousine Bus 600 is the single most useful route for an arriving traveller. It runs from the airport to the Jungmun resort district and on to Seogwipo, stopping at major hotels along the way.
First departure from the airport is 06:30, last is 22:20, with buses every 16 to 40 minutes. Land after that and it is a taxi — worth knowing if you booked a late flight to save money.
For a slower look at the island, two routes trace the ring road, 일주도로 (Iljuro), which circles Jeju completely. Bus 701 runs the eastern side, Bus 702 the western. Riding either end to end is a long day, but the black lava coastline does most of the work for you and it costs almost nothing.
Where the network genuinely thins out is inland. Hallasan trailheads above the coastal band, the entrance to 사려니숲길 (Saryeoni Forest Trail), and most of the island's 오름 (oreum, the small volcanic cones scattered across Jeju) sit beyond convenient bus reach.
That is not a reason to abandon the bus. It is a reason to plan one day around a car or a taxi and use the bus for the rest.
The Part of Jeju the Bus Cannot Reach
There is a band of the island most visitors never see, and it has a name: 중산간 (jungsangan), the mid-elevation zone between Hallasan's slopes and the coastal flats.
This is where the quiet roads run — past stone-walled tangerine groves, through villages that were not built for anyone's itinerary, up to oreum that ask thirty minutes of climbing and hand back a view of the sea on both sides of the island at once.
By bus it is difficult. By car it is twenty minutes uphill from the coast road.
If you take only one thing from this guide, take that. The coastal ring is what Jeju shows you. The 중산간 is what it keeps.

One Structural Thing About Jeju
You arrive and leave through the same airport. There is only one.
That sounds like a limitation and works out as the opposite. Your route has no required direction — clockwise, anticlockwise, or zigzag, it makes no difference as long as you finish where you started. Almost no other island trip gives you that.
Combined with the scale — nothing more than about ninety minutes from anything else — it means the transport decision is genuinely low-stakes. Choose wrong and you lose an afternoon, not a trip.
Step out of arrivals and both options are already there. The limousine buses load to one side, the rental shuttles to the other, and the basalt walls and canola fields start about four minutes later either way. The only real question is how fast you want to pass through them.
