Seoul and Jeju Island are the most popular domestic travel combinations in Korea. Five to six days in Seoul covers the main circuit thoroughly. Two to three days on Jeju adds a completely different natural experience. Here is the complete day-by-day guide.
Jeju Island sits 83 kilometres south of the Korean peninsula and is Korea’s largest island and most popular domestic destination. The combination of Seoul’s urban culture and Jeju’s volcanic landscapes, black lava coast, and slower pace makes it the most balanced trip structure for international visitors with at least 7 days.
Getting from Seoul to Jeju
Jeju is only accessible by flight from Seoul (no ferry or land route exists). The flight from Gimpo Airport to Jeju International Airport takes about 1 hour. The Gimpo-to-Jeju route is the world’s busiest domestic air corridor by passenger count. Airlines: Korean Air, Asiana, Jeju Air, T’way Air, Eastar Jet, and Jin Air all serve the route with flights every 30 to 60 minutes throughout the day.
Fares: budget carriers (Jeju Air, T’way Air) from 30,000 to 60,000 won one-way, booked 2 to 4 weeks ahead. Full-service (Korean Air, Asiana) from 60,000 to 120,000 won. The budget carrier’s quality on this short route is acceptable; the 1-hour flight does not require full-service amenities.
The AREX from Hongik University Station (Hongdae) to Gimpo Airport takes 14 minutes. From Myeongdong, take Line 4 to Seoul Station, then take AREX All-Stop to Gimpo. The Gimpo departure for Jeju is significantly more convenient than the Incheon departure.

Practical Notes
T-money card: Get one at any convenience store. Covers all Seoul and Korean city subway fares. See the T-money guide.
Naver Map: More accurate than Google Maps for Korean transit routing and walking directions.
Jeju car rental: A car or scooter is essential on Jeju. Public transport exists but is slow and infrequent for the dispersed sights. An International Driving Permit (IDP) is required for renting in Korea. Obtain your IDP in your home country before departure. Most car rental companies at Jeju Airport accept international licenses alongside the IDP.
Jeju Travel Tips
Jeju has a mixed climate: subtropical in the south and temperate in the north. It gets much more rain than Seoul, especially along the south coast.
The best times to visit are April to May and October to November, when rainfall is lower, and the scenery is at its most colourful. July to August is hot, humid, and crowded, and usually has the highest Gimpo-to-Jejuju airfares. December to February is cooler, with occasional snow on Hallasan.
Jeju’s food culture is distinct from mainland Korea. Local highlights include black pork, abalone porridge or grilled abalone, mackerel, hanchi mulhoe, and hallabong desserts or juices.
A dedicated dinner at a Jeju black pork restaurant is worth budgeting for, usually around 20,000 to 35,000 won per person.
