Before your trip to Seoul
Flights to Seoul
Seoul is served by two major airports: Incheon International Airport (ICN) and Gimpo International Airport (GMP). Most international long-haul flights land at Incheon. There are numerous carriers offering competitive rates; if you are looking to save on your budget, consider regional budget airlines or booking well in advance for major carriers.
Entry and Visa Requirements
Before heading out to explore all the things to do in Seoul, check your visa requirements. Many nationalities (including US, UK, EU, and Taiwan citizens) can enter visa-free for tourism. However, most travelers are required to apply for a K-ETA (Korea Electronic Travel Authorization) online before departure. Be sure to check the latest official government guidelines as regulations can change.
Currency and Exchange
The exchange rate for Korean Won (KRW) is approximately 1,350 KRW to 1 USD. For those looking for the best rates, currency exchange offices in Myeongdong are generally recommended for having the most competitive rates in the city.
South Korea has a very advanced credit card culture. Most shops, even small ones in non-tourist areas, prefer card payments. It is recommended to carry a travel-friendly credit card with no foreign transaction fees, though keeping some cash for street food or small markets is wise.
Voltage and Plugs
The standard voltage in South Korea is 220V. The power plugs and sockets are of type C and type F (the “pig-nose” style with two round pins). Most travelers will need a travel adapter. If you forget one, you can easily find them at local Daiso stores, though these may not have voltage conversion features for devices like high-powered hair dryers.
Tax Refunds
Shopping is one of the top things to do in Seoul. Many major retailers like Olive Young, department stores, and cosmetic shops offer tax refunds. If your single-receipt purchase is over 15,000 KRW (approx. $11 USD), you can request a tax refund slip. You can process this at airport kiosks or sometimes get an immediate refund in-store. Refunds typically range from 3-7%. Note that for very high-value items, customs may need to inspect your goods at the airport.
Internet and SIM Cards
Staying connected is vital for any Seoul travel guide. You can choose between physical SIM cards or eSIMs, which can be activated immediately upon landing. Most public areas in Seoul also offer free Wi-Fi.

Getting Around Seoul
A crucial tip for this Seoul travel guide: Google Maps is not very accurate in South Korea due to government security regulations. It is highly recommended to download local apps for navigation.
The most popular app is Naver Map (available in English/Chinese), which provides detailed information on shop locations, phone numbers, and even menus. Kakao Map is another great alternative for real-time bus arrivals and subway routes.
