Five days is enough to see two of Korea’s best cities and a slice of its ancient history — all connected by high-speed rail. Here’s a tested route.
Day 1 — Seoul
Arrive, settle in, and explore central Seoul: palaces (Gyeongbokgung), Bukchon Hanok Village, and the markets and food of Myeongdong or Gwangjang.
Day 2 — Seoul
Go wider: Hongdae or Seongsu for cafés and shopping, a city viewpoint, and a day trip option (see our day trips from Seoul guide if you want one).
Day 3 — Seoul → Busan by KTX
Take a morning KTX (~2.5 hrs) to Busan. Drop your bags and head to Gamcheon Culture Village, then fresh seafood at Jagalchi Market and sunset at Haeundae Beach.
Day 4 — Busan (with a Gyeongju option)
Spend the day in Busan, or take a short hop to Gyeongju — the ancient Silla capital — for temples and royal tombs. (Gyeongju is closer to Busan than Seoul.)
Day 5 — Busan → Seoul (or fly out)
Morning in Busan, then KTX back to Seoul for your departure — or fly out of Busan (Gimhae) directly.
Does the Korail Pass pay off here?
With a Seoul⇄Busan round trip plus a Gyeongju hop, you’re taking three or more intercity rides — right in the range where a Korail Pass often beats buying tickets one by one, and it spares you per-trip card checkouts.
