1. Understanding the Seoul Subway System

1.1 Extensive Network

  • 23 subway lines, nearly 300 stations, all clearly color-coded.
  • Each station has a unique number (e.g., Chungjeongno Station is Station 243 on the Green Line).
  • Station numbers and color codes make navigation straightforward, especially for non-Korean speakers.

1.2 Navigation Tools

  • Naver Maps (highly recommended for accuracy and real-time updates)
    • (Android) You can change the appā€™s languageā€”Korean, English, Simplified Chinese, or Japaneseā€”by going to the top-left menu (ā‰”), selecting the settings gear icon, and choosing Language. Language settings are supported on NAVER Map app versions 5.1.3 and later. Version 5.0 and above can only be installed on Android 7.0 and iOS 15.0 or later.
    • (iOS) You can switch the appā€™s languageā€”Korean, English, Simplified Chinese, or Japaneseā€”either from the top-left menu (ā‰”) > settings gear icon > Language, or through your deviceā€™s Settings > NAVER Map > Preferred Language. If the Preferred Language option is not visible under Settings > NAVER Map, go to your deviceā€™s Settings > General > Language & Region to add one of the supported languages (Korean, English, Simplified Chinese, or Japanese).
