Before your first transfer in Korea, install at least one local map app and test it while you still have reliable Wi-Fi.
Korea Tourism Organization's 2026 transportation guide lists KakaoMap and NAVER Map as tools for driving, public-transit and walking route searches. The same guide notes that NAVER Map offers English, Chinese and Japanese interfaces, while KakaoMap offers English. Use the app that best fits your language and route needs.
For transit, search both the destination name and the exact station, terminal or entrance. A place can have several branches or similarly named stops, so compare the Korean address, district and nearby landmarks before starting a route. Save your hotel and major stations in advance so you can recover if mobile data is weak.
Map apps are planning tools, not guarantees that a business is open or that a temporary bus detour is reflected immediately. For airports, rail, ferries, festivals or severe-weather days, cross-check operating information with the relevant official operator.
If you cannot find a place in Roman letters, copy the Korean name or address from the venue's official page and paste it into the map search.
