The first timer's Seoul subway map. Every station a visitor actually needs, in the real line colours, with the reason to get off, the exit to aim for when we've checked it, what's on nearby and the Seoul Sunbae guide to read next. Tap a station. Not every stop is shown, and the map is a diagram, not to scale.
Schematic and simplified: only key stations are shown and distances are not to scale. For every stop, use the official Seoul Metro map or Naver Map.
