One day in Busan from Seoul: the KTX day-trip plan

Busan sits at the opposite corner of Korea from Seoul, yet the KTX bullet train shrinks it to a day trip: roughly 2 hours 15 minutes to 2 hours 45 minutes each way depending on the service, with a standard-class one-way fare of about ₩59,800. Book ahead on weekends — popular trains sell out. Prices and timetables change, so confirm when you book.

The plan

• ~7:00 AM — Seoul Station: the early KTX south, coffee and kimbap for the ride
• Morning — Gamcheon Culture Village: Busan's hillside maze of colorful houses; go early before the lanes fill up
• Midday — Jagalchi Market area: Korea's biggest seafood market; pick your fish downstairs, eat it upstairs
• Afternoon — Haeundae Beach: the city's famous beachfront for a walk, a coffee, and sea air before heading back
• Evening — KTX back to Seoul: a train around 7–8 PM puts you back in Seoul before the subway stops

Honest advice

Three stops is the ceiling for one day — Busan rewards a weekend if you have one. But as a taster, this route covers the city's three personalities: hillside village, working port, and beach resort, all in a single day.
