5 Essential Apps to Have When Traveling in South Korea

1. NAVER Map & KakaoMap – Navigation and Map Apps

Having a reliable map app is essential when traveling around South Korea. It helps you find places, plan routes, and navigate major cities such as Seoul, Busan, and Incheon.

KORAIL+ is the official mobile application of the Korea Railroad Corporation (KORAIL). It was previously known as KorailTalk and was redesigned as KORAIL+ in 2026.

4. Kakao T & k.ride – Taxi Booking Apps in South Korea

Although South Korea has an extensive subway and public bus network, taking a taxi can be a convenient alternative in certain situations. It is especially useful when traveling with luggage, returning from tourist attractions late at night, or visiting places that are not easily accessible by public transportation.

Kakao T

5. Official Transportation Apps & Websites – Check Travel Information Before Departure

In addition to map and taxi apps, checking information directly from transportation providers is important, especially when traveling to the airport or between cities.

Map apps can help you plan routes, but certain details, such as train schedules, last departures, route changes, and booking conditions, should be confirmed directly with the relevant service provider.

Information You Should Check

• Boarding and drop-off locations.

• Ticket prices and fares.

• Airport Bus Operators: Routes, stops, and Airport Limousine schedules.
