The Car Is the Real Question.
Jeju Island travel from Seoul in 2026: Gimpo flights and real fares, the passport rule, rental car or bus, Hallasan bookings, Seongsan hours and how many days.
Getting to Jeju is the easy part. You will spend longer in the terminal than in the air.
The real planning starts at Jeju Airport. The island is bigger than it looks, the sights sit around the edge, and the bus is cheap but slow. Here is how Jeju works in late 2026, from the flight to the last ferry.
Fly from Gimpo Airport. In June 2026 Jeju to Gimpo alone had 3,022 departures, about 100 a day, so departures run from early morning to evening.1 Seat supply did shrink in 2026, so book early for weekends and holidays.1
| Step | What to know |
|---|---|
| Get to Gimpo | Subway Line 5, 9, the Airport Railroad or Gimpo Goldline; see Seoul's subway and buses |
| Flight time | About an hour in the air; airline timetables show about 1 hour 5 to 1 hour 20 minutes gate to gate (Peep check of timetables) |
| Book | On the airline's own site or app; many sell in English |
| Arrive | Jeju International Airport is in Jeju City, on the north coast |
Fares swing hard. In early October 2026, before the Hangeul Day long weekend, some Gimpo to Jeju seats had base fares of 2,000 to 4,000 won, but the fuel surcharge (20,900 won) and airport fee (4,000 won) took one of those tickets to 26,900 won.2 Korean Air's November domestic surcharge rose to 25,300 won one way.2
Q. Why does the ad price never match the checkout price? Because the headline fare leaves out the fuel surcharge and airport fee.2 Compare the total at the payment step, not the first screen.
Q. Is the ferry an option from Seoul? Not a practical one. Ferries to Jeju leave from south coast ports such as Mokpo, about 4.5 to 5 hours at sea, and Jindo, about 2 hours.15 The ferry makes sense if you are already in the south west or bringing a car. (Peep observation)
Your passport, the original. Under Korea's aviation security rules, adults on domestic flights must show valid ID, and for foreign visitors that means a passport (or a Korean residence card if you have one).3
Q. My passport is in the hotel safe in Seoul. Can I fly with a photo of it? No.3 Go back for it; it is the one item you cannot fix at the airport.
If your passport normally needs a visa for Korea, Jeju may still let you in without one. The island's own rule allows up to 30 days, on Jeju only, when you fly directly to Jeju from abroad.4, 5 If your passport already gets you into Korea visa-free, nothing changes for you.
Most readers will come via Seoul on a normal entry, so this rule will not matter to them. Your general entry checklist, K-ETA dates included, is in Korea entry requirements.
Q. I entered on the Jeju visa-free rule. Can I then fly to Seoul? Not by default. The rule limits your stay to Jeju.5 Ask Korea Immigration before you book that flight; the embassy notice lists its English call center.4
Not strictly, but it changes the trip. A car turns Jeju into a loose, stop-anywhere island; the bus works well if you pick one base and accept fewer sights per day. (Peep observation)
| Rental car | Bus | |
|---|---|---|
| Paperwork | International Driving Permit, passport, your own credit card, and for some firms your home license6 | A tap card or contactless bank card7, 8 |
| Cost per ride | Rental, fuel, parking | 1,150 won by card on regular buses7 |
| East and west coast in one day | Easy | Long; plan one side per day (Peep estimate) |
| Udo Island | Rental car usually not allowed on the island14 | Walk on, then bus or bike |
| Hallasan trailheads | Seongpanak parking fills very early10 | Buses 281 and 181 stop there10 |
Rental car rules for foreigners, per the Korea Tourism Organization6:
That page was last updated in 2021, so confirm the rules with your rental company when you book.6
Q. Can I just use my US or UK license? Not on its own for a rental. Korea asks for a valid IDP, and an "International Driving License" bought online is not the same thing.6
Regular and tourist circular buses cost 1,150 won with a card or 1,200 won in cash, and the red express buses start at 2,000 won by card for the first 20 km, up to 3,000 won.7 Tap when you get off on express buses, because the extra distance is charged then.7
Q. Are taxis expensive in Jeju? Fine for short hops in town; a cross-island ride adds up fast. (Peep observation) Taxi apps work as they do in Seoul.
Stay in Jeju City for the airport, late flights and the most food; stay on the Seogwipo side (including Jungmun) for the south coast, waterfalls and a slower, warmer feel. (Peep observation)
| Base | Good for | Trade-off |
|---|---|---|
| Jeju City | First and last nights, flights, markets, bus hub | Sights are an hour or more away |
| Seogwipo town | South coast walks, the harbor, bus links east and west | About 1.5 to 2 hours from the airport by bus9 |
| Jungmun | Resort area, beaches, the airport limousine | Quiet at night, few cheap eats |
| East coast near Seongsan | Sunrise at Seongsan Ilchulbong, Udo | Far from everything else |
The car-free version that works: two nights in Jeju City, two nights in Seogwipo. (Peep estimate)
Start with three: Seongsan Ilchulbong for the crater and sunrise, Udo for a slow island loop, and Hallasan if you hike. Fees below were checked on 29 October 2026.
| Sight | Fee and hours | Rule that catches people |
|---|---|---|
| Seongsan Ilchulbong | Adults 5,000 won; 06:00 to 18:00 from November to February, last ticket an hour before closing13 | Closed the first Monday of each month13 |
| Udo | Ferry from Seongsan Port | Rental cars are restricted on the island until 31 July 202914 |
| Hallasan summit | No admission charge listed; summit booking needed on two trails10, 18 | Booking opens on the first working day of the previous month10 |
Seongsan Ilchulbong is a 180 meter tuff cone with a crater about 600 meters across.13 From March to October it opens before dawn (05:00, or 04:30 in summer), which is how people catch the sunrise from the top.13 The climb is short but steady; go early to beat the tour groups. (Peep observation)
Udo sits just off Seongsan. Jeju has extended its limit on rental cars, chartered buses and some two-wheelers on Udo to 31 July 2029, with exceptions for travelers with disabilities, older people or small children, low-emission cars and 16-seat buses.14 In practice, walk on, then bike or take the island bus. (Peep observation)
Q. Is Seongsan Ilchulbong open on Mondays? Yes, except the first Monday of the month; if that day is a public holiday, it closes the next day instead.13
Only the summit sections need a booking: Seongpanak (from Jindallaebat shelter up) and Gwaneumsa (from Samgakbong up). Eorimok, Yeongsil, Donnaeko and the other trails need no reservation.10
| Rule | Detail |
|---|---|
| Where | visithalla.jeju.go.kr, the park's booking site10 |
| When it opens | 09:00 on the first working day of the previous month10 |
| Daily places | Seongpanak 800 for 05:00 to 08:00 and 200 for 08:01 to 11:30; Gwaneumsa 400 and 10011 |
| Group size | Up to 4 people per booking, once a week10 |
| At the gate | One QR code per person plus ID10 |
| Cancel | Before the end of your time slot, or you get a penalty10 |
The Gwaneumsa summit section reopened on 24 September 2026 after rockfall work.12 Seongpanak has no shop, so carry food, water and rain gear, and crampons in winter.10 Bring your passport as the ID. (Peep check)
Q. I could not get a summit slot. Is Hallasan still worth it? Yes. Yeongsil and Eorimok climb to high ridges with big views and no booking. (ref. 10; Peep observation)
Milder than Seoul, but windy. Winter brings a steady north west wind to Korea, and Jeju's coasts feel it. (ref. 16; Peep observation)
For the whole-country calendar, see when to visit Korea, season by season. For layering for the cold months, see Seoul in November and December.
Q. Can I swim in Jeju in November? Most visitors do not; the beaches are for walks this time of year. (Peep observation)
Three full days covers the east, the south and one Hallasan or west day. Four or five lets you slow down and absorb a weather day. (Peep estimate)
A simple four-day shape (Peep estimate):
Q. Is a day trip from Seoul possible? Technically yes, with the first and last flights. It is a lot of airport for one view. Give Jeju at least two nights. (Peep estimate)
Q. Jeju or Busan? Different trips. Busan is a city with beaches, two to three hours by train; Jeju is an island of nature that needs a flight. See Seoul to Busan by KTX.
Passport, IDP if you drive, a contactless card, and a layer for the wind. (ref. 3, 6, 8; Peep observation)
About an hour in the air from Gimpo. (Peep check of timetables) Timetables show about 1 hour 5 to 1 hour 20 minutes.
Sale seats in October 2026 came to about 26,900 won all in.2 Weekend and holiday flights cost more; compare the final total. (Peep observation)
Yes. Bring the original, valid passport.3 Copies, photos and screenshots are refused.
If your nationality needs one for Korea, yes, unless it is exempt through 31 December 2026.4 Check Korea entry requirements.
Yes, with an IDP under the Geneva or Vienna convention, your passport and a credit card.6 The names on the IDP and passport must match.
No, but it saves a lot of time. (Peep observation) Without one, base yourself in Jeju City and Seogwipo.
1,150 won by card on regular buses; express buses from 2,000 won.7 Tap off on express buses.
Yes, contactless overseas cards work on Jeju city buses since August 2025.8 Tap the card or your phone.
