The small things that trip people up on a first trip to Korea, sorted before you fly.
Check whether your nationality needs a K-ETA (Korea Electronic Travel Authorization) or a visa before you book. Apply only on the official site, k-eta.go.kr.
Google Maps shows places but gives limited walking and driving directions in Korea. Install Naver Map or KakaoMap (both have English menus) before you arrive.
Buy a T-money card at the airport or any convenience store and top it up with cash. It works on subways, buses and many taxis across the country.
Taxis are easy to hail in big cities. The Kakao T app lets you book one and show the address in Korean.
Pick up a prepaid SIM or eSIM at the airport, or rent a pocket Wi-Fi router. Arrival halls at Incheon and Gimpo have counters for all three.
Most shops, restaurants and taxis take international cards. Keep some cash for small restaurants and markets.
Tell restaurants about allergies clearly; many dishes use sesame, soy, garlic and seafood-based sauces. Mild dishes such as gomtang (beef bone soup), bibimbap and bulgogi are an easy start.
Shops with a "Tax Free" sign can refund VAT on qualifying purchases. Keep your passport handy and ask at the counter or at the airport refund kiosks.
The Korea Travel Hotline 1330 answers in English and other languages, and can interpret with a taxi driver or restaurant over the phone.
Rules change. Check official sources before you travel.
