How to Travel from Seoul to Jeju Island: Flights (Gimpo) vs Ferries

Flying from Gimpo to Jeju

Multiple domestic carriers operate frequent flights between Seoul's Gimpo Airport and Jeju International Airport, with a flight time of roughly one hour. This is the route most visitors use because of frequency and speed, but Gimpo is a separate airport from Incheon -- if you are arriving internationally through Incheon, budget time to transfer between airports before your domestic flight.

• Check-in typically closes 20-30 minutes before domestic departure -- earlier than international norms, so don't assume international-flight timing.
• Baggage allowances differ by carrier and fare class; low-cost carriers often charge separately for checked bags.
• Jeju Airport sits close to central Jeju City, with airport buses and taxis to most parts of the island.

Taking a ferry from the mainland

Ferries to Jeju depart from several mainland ports, most commonly around the southern coast, with both day and overnight sailings depending on the operator and season. Ferry travel takes considerably longer than flying -- often several hours to overnight -- but it is the practical choice if you are bringing a car onto the island or traveling with bulky luggage or equipment that would be awkward or costly to check on a flight.

1. Confirm the departure port -- mainland ferry terminals for Jeju are not all in the same city, so check which port matches your starting point.
2. Vehicle bookings for car ferries fill up separately from passenger seats and should be reserved well in advance.
3. Sailings can be cancelled or delayed by weather, especially in typhoon season -- build in a buffer day if your onward plans are tight.

Which to choose

For most short trips without a car, flying is faster and usually not much more expensive once you account for a full day of ferry travel. Choose the ferry if you're bringing your own vehicle, traveling with a group and heavy gear, or specifically want the slower coastal journey as part of the trip.
