Navigating Seoul Station: Finding Your AREX Platform

Seoul Station is one of South Korea's busiest transportation hubs, serving KTX high-speed trains, various subway lines (Line 1, Line 4), and, of course, the AREX line. Its sheer size can be daunting for first-time visitors, but clear signage makes navigation manageable. To catch your train to Gimpo Airport, follow these steps:

1. Arrive at Seoul Station: Whether you're coming from another subway line, a bus, or a taxi, make your way into the main station complex.

It's always a good idea to allow yourself an extra 10-15 minutes, especially if you're unfamiliar with Seoul Station, to comfortably find your way to the AREX platforms without feeling rushed. The station also offers various amenities, including shops, cafes, and restrooms, should you need them before your departure.
