KTX Honam and Jeolla Line: Yongsan to Gwangju and Yeosu

Honam Line vs Jeolla Line

The Honam Line branches southwest from the Gyeongbu corridor toward Gwangju and the greater Jeolla region, while the Jeolla Line continues further to reach Yeosu on the south coast -- together these lines serve Korea's southwestern quadrant, an area with a genuinely distinct food culture and slower-paced regional character compared to the busier Gyeongbu corridor cities.

Gwangju and Yeosu as destinations

• Gwangju is a major regional city known for its arts scene, notably the Gwangju Biennale, and a food culture distinct from Seoul's.
• Yeosu is a coastal city known for its night skyline, cable car, and seafood, having gained additional visibility after hosting a major international expo.
• Both cities see considerably fewer international visitors than Busan or Jeju, appealing to travelers looking for a less-touristed regional trip.

Departure station: Yongsan, not Seoul Station

Most Honam and Jeolla Line KTX services depart from Yongsan Station rather than the more centrally known Seoul Station, so double-checking your ticket's departure point before travel day matters more on this route than on the Gyeongbu Line, where confusion between Seoul Station and Yongsan is also possible but slightly less common in practice. Yongsan Station is well connected by subway and is itself a large, modern transit hub with plenty of dining options for a pre-departure meal.

The Honam and Jeolla lines see noticeably less tourist traffic than the Gyeongbu Line to Busan, which can mean more seat availability but also less frequent departures throughout the day, so checking the schedule in advance matters more on this route. Gwangju serves as a natural base for exploring the wider Jeolla region's food and cultural attractions, while Yeosu's coastal setting makes it a popular endpoint for travelers seeking a seaside finish to a rail trip. Both cities are reachable directly from Yongsan Station rather than requiring a transfer through Seoul Station.
