Visit Jeonju describes KTX travel from Seoul to Jeonju as approximately 1 hour 40 minutes. It advises searching Yongsan → Jeonju as well as Seoul Station departures because Yongsan has more services on the referenced route.
Use Korail's official website or KorailTalk, a station counter or a ticket machine. International visitors can consult the multilingual booking interface. Before departure, confirm the train number, platform, carriage and seat; seats may sell out during busy periods.
