Getting around South Korea without overpaying for rail
How KTX, SRT, express buses and the Tmoney card actually fit together, when the KORAIL Pass is worth buying, and why Jeju needs a car booked before the room.
16-day trip
A linear route south from Seoul through Jeonju, Gyeongju and Busan, finishing with four days and a rental car on Jeju rather than squeezing the island into a long weekend.
Planning budget
≈ €1,734(₩2,800,000 original)Rate snapshot 2026-08-26The shape here is deliberate: the mainland stays a straight line running south-west then east, and Jeju comes last, reached by a short flight from Busan rather than a return to Seoul. That ordering saves a full day compared with the common mistake of flying the island out of Incheon in the middle of the trip.
Four days on Jeju is the minimum that justifies the flight and the rental desk. Book the car before the room — supply tightens on weekends and holidays — and bring your home licence, passport and a valid International Driving Permit obtained before you leave home. Any Hallasan summit route needs an advance reservation.
Keep the last mainland day flexible if you are travelling in late summer. Typhoons do cancel Jeju flights, and a spare day at the end of the route is the difference between a rearranged afternoon and a missed connection home.
The route
Tmoney card, express train into the city, and an early night after one short walk and a meal near the room.
Seoul
Gyeongbokgung at opening, Changdeokgung's rear garden if slots remain, then the Bukchon lanes on foot.
Seoul
Gwangjang at lunch, the afternoon in Ikseon-dong, and the evening in the printing alleys as they turn into bars.
Seoul
A daytime market or gallery, then the university district after dark for the loudest, cheapest food in the country.
Seoul
Bukhansan or Inwangsan by subway and bus, back in the city for the afternoon, and bags packed for an early train.
Seoul
Under two hours south-west. Check into a hanok inside the village and walk the quarter after six, when the day trippers have gone.
Jeonju
Bibimbap at an old-established house, the shrine and the paper workshops, then a makgeolli house for the evening.
Jeonju
Cut east by train and bus, then take a bicycle around the burial mounds and Cheomseongdae in the afternoon.
Gyeongju
The temple terraces and the grotto Buddha in the morning, the lit pond at Donggung after dark.
Gyeongju
Half an hour on the train, then Jagalchi market and the hillside lanes of Gamcheon before the light goes.
Busan
Haedong Yonggungsa near opening, the coastal walk afterwards, and Gwangalli in the evening.
Busan
The beaches, a bathhouse or the modern art on Yeongdo, keeping the day to one side of the city.
Busan
Under an hour from Gimhae. Collect the rental car, allow for the off-airport shuttle, and drive east to your base.
Jeju
Seongsan Ilchulbong early, the ferry across to Udo for the black cliffs, and Manjanggul on the way back.
Jeju
A reserved summit route if the weather holds and you booked it, or the quieter western beaches and coast road if not.
Jeju
Return the car with fuel and shuttle time to spare, and fly home via Seoul or Busan.
