How to get to Jeju from Seoul: flights, ferries and getting around the island

Jeju is an island off the south coast, so there’s no train and no bridge. You’re choosing between a short flight that most Koreans treat like a bus ride and a longer trip by rail and sea that hardly any visitors bother with. Then, once you land, you have a second decision that matters just as much: how you’ll get around an island where the good parts are spread out.

The short version

Fly from Gimpo. It’s Seoul’s domestic airport, it’s on the subway, and Gimpo to Jeju was the busiest air route in the world in 2025, so there are flights from early morning to night. Book a few days ahead, especially for weekends and holidays, and you’ll have plenty of choice.

Take the ferry only if the journey appeals to you or you’re bringing your own car. The realistic sea routes start on the southwest coast (Mokpo or Wando), so a ferry trip from Seoul is a full day of train or bus plus boat.

Once on Jeju, rent a car if you can drive and have the right permit. If not, buses work with a tap of a Visa card, and taxis fill the gaps.

Flying from Gimpo

Gimpo Airport is on the Airport Railroad (AREX) all-stop line and the subway, so you can reach it on a T-money card from most of the city.

OAG counted about 14.4 million scheduled seats between Jeju and Gimpo in 2025, around 39,000 a day, spread across seven airlines. Jeju Air runs the most flights on the route, and from March 29, 2026 it went up to as many as 26 round trips a day, roughly one every 30 minutes on average. Korean Air and Asiana fly it too. As a condition of their merger, some of their Gimpo to Jeju slots were reassigned in January 2026 to Eastar Jet, Jeju Air, T’way Air and Parata Air, so expect a lot of low-cost options.

Time in the air is around an hour and ten minutes. Add the subway ride to Gimpo, check-in, security and boarding, and door to door is often similar to the KTX to Busan, sometimes longer.

Fares move a lot with the day, the time and school holidays. Comparing two or three airlines for the same day is worth the five minutes.

Flying from Incheon

Most visitors land at Incheon, and the obvious question is whether you can connect straight to Jeju without crossing Seoul. Usually not. Incheon to Jeju flights only came back in 2026, after about ten years without them. Korean Air’s transfer-only domestic flights from Incheon go to Busan and Daegu, not Jeju.

In 2026, Jeju Air started a twice-weekly Incheon to Jeju route on May 12. It departed Incheon at 6:05 p.m. and landed at 7:25 p.m. at launch, and the airline extended it through October 24, 2026 after load factors of about 88%. About 30% of its passengers were foreign. Whether it runs beyond the summer schedule wasn’t announced when we checked, so look it up for your dates.

If it doesn’t fit, the usual move is to take the AREX all-stop train from Incheon to Gimpo and fly from there. If you’re arriving on a long-haul flight, a night in Seoul first is less stressful than chasing a same-day connection. Our Incheon Airport guide covers the train.

Ferry options

Before the Sewol disaster in 2014, about three in ten visitors reached Jeju by ferry. Numbers fell after that, and several long routes have since closed.

Mokpo to Jeju. This is the main route from the west. Seaworld Express Ferry runs large car ferries, and Mokpo City’s timetable shows crossings of roughly four to four and a half hours. Getting to Mokpo is easy: the Honam high-speed line brought the fastest KTX from Yongsan to Mokpo down to about 2 hours 15 minutes. One of the line’s ships, the Queen Zenobia 2, ran aground in November 2025 and was taken out of service for repairs, so check which ships and sailings are running before you plan around one.

Wando to Jeju. The shortest crossing from the mainland. Hanil Express’s Silver Cloud was reported at about two and a half hours when it entered service, and the route is still sold to foreign travelers in 2026. Wando has no train station, so you’d get there by long-distance bus, which makes the whole trip from Seoul long.

Busan to Jeju. The overnight passenger ferry stopped in December 2022 when its ship was sold, and as of early 2024 Busan’s maritime office was still looking for a new operator. We couldn’t confirm a restart, so treat this route as unavailable unless you find a current timetable.

Incheon to Jeju. Suspended since April 2023, and the operator left the route. There’s no ferry from the Seoul area.

For booking, Klook already sells Mokpo to Jeju and Wando to Jeju tickets for foreign travelers, with a wider ferry booking service due in late 2026. Keep your passport with you for booking and boarding. Rough seas can cancel sailings, so a ferry trip needs a flexible day.

Seoul to Jeju compared

Getting around Jeju

Buses. Jeju’s buses are cheap and cover the whole island. In early 2025 a regular city bus cost 1,150 won by card, and express buses that serve the airport cost around 2,000 won, more for longer trips. Since August 2025 about 800 city buses have accepted tap payment with overseas cards, and the Korea Herald reports that Jeju is the only place in Korea where an overseas Visa card works on transit without a separate transit card. A T-money card works as well. The catch is frequency: buses run less often than in Seoul, and sights are far apart. Jeju’s official bus information site has route search and real-time bus locations, and Naver Map shows Jeju bus routes too.

Rental car. Most visitors on a short trip rent a car, and it changes what you can fit into a day. You need an International Driving Permit issued by a country party to the Geneva or Vienna road traffic convention, plus your original license and your passport. A license from home on its own isn’t accepted. The permit is valid for one year from the date you enter Korea. Rental companies set their own minimum age and years-of-driving rules, so check before you book.

Taxis. Taxis are the fallback when a bus would mean a long wait. Without a license, a sensible pattern is buses for the long legs and a taxi for the last few kilometers, and fares add up quickly on longer rides across the island. Our taxi guide covers apps and paying by card.

Mistakes that catch visitors out

Arriving without the right permit. Some apps and sites call it an “international driver’s license”. What counts is the official International Driving Permit issued in your home country, and rental agencies won’t accept a foreign license without it.

Booking a Jeju flight on the same day you land at Incheon. Immigration, baggage and the transfer to Gimpo add up. Give yourself a big buffer or stay a night in Seoul.

Booking the last flight out of Jeju before an international departure. Wind and storms do delay and cancel Jeju flights. Leave a night in Seoul before you fly home if you can.

Assuming a ferry from Busan. Older guides still list it. Check for a current timetable before you build a plan around it.

Trying to circle the island by bus in two days. Pick one or two areas, like the east coast around Seongsan or the south coast around Seogwipo, and keep the rest for next time.

Ignoring the calendar. Flights get busy and fares climb around Seollal, Chuseok and summer school holidays. Our guide to the best time to visit Korea lists the 2026 and 2027 holiday dates.

What we’d do

First trip, a few days spare: fly Gimpo to Jeju in the morning, pick up a rental car at the airport, and base yourself on one side of the island. Fly back the evening before you leave Korea, not the same day.

No driving license: still fly. Stay somewhere central to bus routes in Jeju City or Seogwipo, use your Visa card on buses, and budget for a few taxi rides.

Landing at Incheon and heading straight to Jeju: check Jeju Air’s Incheon to Jeju schedule for your date. If it doesn’t line up, take AREX to Gimpo or spend a night in Seoul first.

You want a sea crossing: KTX from Yongsan to Mokpo, then the ferry. Pick a calm season, keep a spare day, and confirm the sailing a few days before.

Questions people ask

How long is the flight from Seoul to Jeju?

About an hour and ten minutes in the air from Gimpo. Allow for the trip to the airport, check-in and boarding on top of that, so door to door is often similar to the KTX ride from Seoul to Busan, or a little longer.

Can I fly to Jeju from Incheon Airport?

Sometimes. Jeju Air started a twice-weekly Incheon to Jeju route on May 12, 2026 and extended it through October 24, 2026. Most domestic flights to Jeju leave from Gimpo, so check the schedule for your dates.

Is there a ferry from Seoul to Jeju?

Not directly. The Incheon to Jeju ferry stopped in 2023. The practical sea routes leave from Mokpo and Wando on the southwest coast, which you reach by KTX or bus.

Can foreigners rent a car in Jeju?

Yes, with an International Driving Permit from a Geneva or Vienna convention country, your original license and your passport. The permit is valid for one year from your arrival in Korea.

Can I pay for Jeju buses with a foreign card?

Yes, if it's a Visa card. Jeju was the first place in Korea to let overseas cards tap on city buses, and about 800 buses take them. A T-money card works too.
