How to Sequence a South Korea Itinerary
- Group Seoul, Gyeongju, and Busan on a single KTX spine: Take the KTX from Seoul Station to Gyeongju Station (2h 05m, ₩49,300), spend 1–2 nights exploring Silla royal tombs and Bulguksa Temple, then hop 30 minutes south by KTX (₩11,000) to Busan Station.
- Fly between Busan (PUS) and Jeju Island (CJU), then Jeju to Seoul Gimpo (GMP): Instead of backtracking by train, take a 55-minute domestic flight from Busan to Jeju Island, and fly from Jeju directly into Seoul Gimpo Airport (GMP)—just 22 minutes by AREX subway from Hongdae and Seoul Station.
