Sejong to Seoul Map

Plan your trip from Sejong to Seoul using the Gyeongbu High-Speed Line. The journey starts at Osong Station, passing through Cheonan-Asan and Gwangmyeong before reaching Seoul Station. The route traverses the central plains of South Korea, offering views of suburban developments and industrial landmarks. Using this rail corridor allows for a direct link from the administrative center to northern Seoul in less than an hour.

Rail vs Bus vs Plane

Rail travel from Osong (Sejong) to Seoul is significantly faster than the bus, which can be affected by heavy traffic on the Gyeongbu Expressway. While buses are frequent, the train provides a direct city-center connection to Seoul Station or Yongsan Station. Flights are not a practical option for this short distance. The KTX remains the most time-effective choice for travel between these two cities.
