The KTX high-speed train runs from Seoul Station to Ulsan (Tongdosa) station in about 2 hours 10 minutes. KTX Ulsan station is 20 km west of the city centre, so add 30 minutes for the bus or taxi into town. Door-to-door, the train and flight are comparable at about 2.5 to 3 hours total. The train runs more frequently and has no security screening overhead.
Ulsan Airport (USN) is a small single-runway domestic airport. The terminal is compact with limited food options. It sits about 10 km south of the city centre. Taxis and airport buses connect to downtown Ulsan and the industrial district. Parking is free and readily available.
Ulsan is South Korea's industrial powerhouse. Hyundai Motor, Hyundai Heavy Industries, and SK Energy all have their main production facilities here.

Seoul Gimpo to Ulsan: Capital to Industrial Hub

Seoul Gimpo to Ulsan covers 340 km in about 55 minutes. Korean Air operates 3 to 5 daily flights on the route using narrowbody jets. Gimpo Airport handles Seoul's domestic network and sits closer to the city centre than Incheon, making it the preferred departure point for domestic business travellers.

Ulsan is South Korea's manufacturing capital, home to Hyundai Motor's main assembly plants, Hyundai Heavy Industries' shipyard, and major petrochemical facilities. This makes GMP-USN a corporate commuter route with heaviest loads on Monday mornings and Friday evenings. The KTX high-speed train offers a competitive alternative at 2 hours 10 minutes, but the KTX station sits 20 km outside Ulsan proper. Ulsan Airport is a compact domestic facility with quick turnaround times and taxi access to the city and industrial zones.
