Seoul Subway Transfers: Which Stations Have the Longest Walks

Not all transfers are a quick cross-platform switch -- some involve several minutes of corridors and stairs between lines.

Tip: A maps app's subway directions usually factor in walking time between platforms already -- if a route estimate looks unusually long for a "same station" transfer, that's a sign it's one of the long ones.

Why some transfers take far longer than others

Seoul's subway system was built out over decades by different operators and construction phases, so lines sharing a station name don't always share a platform level or even a connected concourse built at the same time. Some transfers are a short cross-platform walk; others require going up or down multiple levels and walking several hundred meters of connecting corridor, especially at older or more complex interchange stations.

Transfers worth planning extra time for

  • Large multi-line interchanges like Gongdeok, Wangsimni and Dongdaemun History & Culture Park are known for longer connecting walks than a typical two-line transfer.
  • Transfers between older lines (1-4) and newer lines built later (Bundang, Shinbundang, Gyeongui-Jungang) tend to involve more walking since they weren't designed as a single connected structure from the start.
  • Exact walking times shift as stations get renovated, so treat any specific number as approximate rather than fixed.

Practical tips for a tight connection

If you have a train or flight to catch, build in extra buffer specifically around a transfer rather than assuming every change of line takes the same time.

  1. Check your maps app's estimated transfer time before treating a multi-line route as fast, rather than assuming all transfers are equally quick.
  2. Follow the overhead line-color signage rather than guessing -- long transfer stations are usually well signed, just long.
  3. When timing is tight, consider whether a single-line route (even if it takes a few extra stops) beats a shorter-looking route with a long transfer in the middle.

None of this means a long transfer should be avoided outright -- these are still normal, everyday interchanges used by millions of commuters -- it just means the phrase "same station" can hide a genuine walk. Treating a long-transfer station like its own short leg of the journey, rather than an instant hop between lines, is usually enough to keep a tight schedule intact.
