90 to 60 Days Before Departure: Route, Flights & Base Hotels
First-time visitors get the smoothest experience by grouping nights into 2 or 3 main bases rather than changing hotels every day. On a classic 7-to-10-day trip, book Seoul (4–5 nights), Gyeongju (1–2 nights), and Busan (2–3 nights) linked by the KTX Gyeongbu high-speed rail line, or add a 55-minute domestic hop from Busan (PUS) to Jeju Island (3 nights) before flying straight back to Seoul Gimpo (GMP). If possible, book an open-jaw international ticket into Incheon (ICN) and out of Busan (PUS), or fly Jeju → Gimpo on your final morning so you never backtrack the length of the peninsula by rail.
In Seoul, first-timers should choose a hotel within a 5-minute walk of a Line 2, Line 3, or AREX transfer station—specifically Myeongdong / Euljiro (central walking access to street food, Lotte Department Store, and Cheonggyecheon), Jongno / Insadong / Gwanghwamun (steps from Gyeongbokgung and Changdeokgung Palaces), or Hongdae (Hongik Univ. Station) (direct 52-minute AREX train from Incheon Airport, vibrant dining, and youthful busking streets). In Busan, split your choice between Haeundae / Gwangalli Beach for oceanfront views or Seomyeon / Nampo-dong for transit and traditional fish markets.

30 Days Out: KTX High-Speed Trains & Time-Sensitive Tickets
South Korea's KTX booking window opens 30 days before departure at 07:00 KST on the official LetsKorail website and KorailTalk app. While weekday midday trains rarely sell out until the day before, Friday evening through Sunday night trains on the Seoul–Gyeongju–Busan and Yongsan–Jeonju corridors regularly sell out of seated tickets a week in advance. Reserve your seat numbers early and screenshot the QR ticket—there are no ticket gates at Korean train stations; conductors verify seat occupancy electronically on board.
Two non-rail tickets also require advance booking: the Haeundae Blueline Park Sky Capsule in Busan (which opens 2–4 weeks ahead and sells out fast for the 16:30–18:00 golden-hour slot between Mipo and Cheongsapo) and the Changdeokgung Palace Huwon (Secret Garden) English-guided walk in Seoul, which releases online reservations 6 days ahead at 10:00 KST.
7 Days Out: The Essential Korea App Stack & 220V Hardware
Before leaving home, download and configure five free apps while you can still receive SMS verification codes on your home SIM card:
- Naver Map (set language to English in Settings): The gold standard for Seoul and Busan subway exits, real-time bus arrival countdowns, walking routes, and restaurant opening hours.
- Kakao T: Korea's dominant taxi-hailing app. Register with your home phone number; when hailing a General Taxi inside Korea, choose "Pay to Driver" so you can tap your physical foreign Visa/Mastercard or T-money card at the end of the ride.
- Papago: Naver's AI translator, far more accurate than general translators for Korean restaurant menus (use the live camera image mode) and voice conversations.
- Subway Korea or KakaoMetro: Shows exact train car and door numbers (e.g., Car 4, Door 2) for the fastest escalator transfer at mega-stations like Seoul Station, Chungmuro, and Sindorim.
- CatchTable Global: Lets foreign visitors book popular Korean BBQ, Hanwoo beef, and fine-dining tables or join remote waiting queues in English without a Korean mobile number.
Check your electronics: South Korea uses 220V / 60Hz electricity with recessed round two-prong Type C and Type F (Schuko) sockets. Phone, tablet, and laptop USB-C chargers are almost universally dual-voltage (100–240V) and only need a simple 4.8mm round-pin plug adapter, whereas 110V North American or 100V Japanese hair dryers and curling irons will overheat or trip breakers unless rated for 220–240V.
First 60 Minutes at Incheon International Airport (ICN)
Once you clear immigration and customs at Incheon Terminal 1 or Terminal 2, follow this exact sequence in the Arrivals Hall before heading downstairs to the B1 rail concourse:
- Connect to Data: Turn on your pre-installed eSIM (or pick up your reserved physical SIM / KT, SK Telecom, or LG U+ counter eSIM near Gates 6–10 in T1 or Gates 2–5 in T2) using the free
AirportWiFinetwork. - Withdraw ₩100,000–₩150,000 Cash or Load WOWPASS: Use a Global ATM marked with Visa/Plus or Mastercard/Cirrus (Woori, Shinhan, KB Kookmin, or Hana Bank in the arrivals hall) and choose the 50,000-won + 10,000-won mix, OR insert your foreign currency notes into a WOWPASS kiosk on the B1 AREX floor.
- Buy & Charge T-money: Step into the CU, GS25, or 7-Eleven convenience store on the arrivals or B1 rail level, buy a T-money card (₩4,000–₩5,000), and ask the cashier to load ₩30,000 in cash per person.
- Board AREX or Airport Limousine Bus: Follow the blue/orange signs to B1 for the AREX Express Train (43 minutes non-stop to Seoul Station, ₩11,000 reserved seat) or the AREX All-Stop Train (52 minutes to Hongik Univ. Station / 59 minutes to Seoul Station, ₩4,450–₩4,750 with T-money).
Frequently asked questions
Do US, UK, EU, Canadian, or Australian citizens need a K-ETA right now?
Passport holders from the 22+ visa-waiver countries covered by the temporary K-ETA exemption (including the US, UK, Canada, Australia, New Zealand, Japan, Taiwan, Singapore, and EU Schengen states) do not need a K-ETA to enter South Korea for short-term tourism. If you do not hold a K-ETA, you simply complete the free Korea Electronic Arrival Card (e-Arrival Card) online within 72 hours of arrival or fill out the paper arrival card on the plane.
Why doesn't Google Maps work properly in South Korea?
South Korean national security regulations prohibit exporting high-resolution government map data to servers located outside the country. As a result, Google Maps cannot compute walking or driving directions in Korea. Download Naver Map or KakaoMap—both support full English interfaces and search.
How much Korean Won cash should I carry for a 10-day trip?
South Korea is 90% cashless at hotels, restaurants, cafes, and department stores, which accept foreign chip-and-PIN or contactless Visa and Mastercard. However, you still need roughly ₩100,000–₩150,000 ($75–$110) per person in physical cash across a 10-day trip to top up T-money transit cards and pay street-food vendors at Gwangjang, Myeongdong, and Jagalchi markets.
