Details
Plan the first trip around Seoul, not the whole country. Five to seven nights gives you palaces, markets, museums and one day out (Suwon or the DMZ) without living on trains. Add Busan only when you have three nights to spare; the KTX line Seoul – Daejeon – Daegu – Busan makes it a comfortable 2 h 30 hop, and you can fly home from Busan (PUS) instead of backtracking.
Land at Incheon (ICN) before 22:00 if you can. The AREX train runs to Seoul Station and is the default way in; late arrivals push you onto taxis or a first night near the airport. From Gimpo (GMP) the subway and AREX also reach central Seoul.
Get a rechargeable transit card (T-money and similar) at the airport or any convenience store, load it with won, and tap on buses and the subway. Cards are accepted almost everywhere, but small market stalls, some taxis and older eateries still prefer cash, so keep a modest amount of won on you. Tipping is not part of the culture.
Book the big-ticket items ahead: the Secret Garden tour at Changdeokgung sells out, and the Royal Palace combined ticket covers four palaces plus Jongmyo. For the DMZ, tours leave from Seoul and need passport details in advance.
Expect limited English outside hotels, stations and tourist areas. Offline translation and map apps solve most of it; download them before you fly. Check entry rules early — K-ETA or visa-free access depends on your passport, and the rules change.

Tips
Do not over-schedule. Seoul rewards slow days: one palace area, one market, one neighbourhood evening. Trying to tick off five cities in a week is the most common first-trip mistake.
Rush hour on the Seoul subway is genuinely crowded; shift your day by an hour and it is fine. Taxis are metered and cheap by US standards, but drivers rarely speak English — have the destination written in Korean.
Check the season before you commit. Spring and autumn are the comfortable windows; summer is hot and wet, winter is cold and dry. Public holidays and Lunar New Year or Chuseok can close small businesses and fill transport.
Questions people ask
What should first-time visitors know about South Korea?
Base in Seoul for 5–7 nights, land at Incheon before 22:00 and take the AREX train, get a rechargeable transit card, and carry some won for small places. Add Busan by KTX only if you have three extra nights.
How many days do I need in South Korea?
Five to seven nights covers Seoul well with one day trip. Ten days lets you add Jeonju, Gyeongju and Busan along the KTX line. Two weeks adds Jeju, which needs a car and three to four nights.
What are the biggest mistakes tourists make in South Korea?
Cramming too many cities into one week, arriving after the last convenient airport train, relying only on cards at markets, and skipping advance bookings for the Secret Garden tour or the DMZ. Limited English outside tourist areas also catches people out.
