How many days do I need for a first trip to Seoul?
Allow four full days for a satisfying first visit; three works only if you focus on the historic north plus one modern/nightlife district. Plan no more than two major sights a day, because cross-city moves regularly take 35–60 minutes door to door.
Where should a first-time visitor stay in Seoul?
Stay north of the Han for the easiest first trip: Jongno/Anguk for palaces and old Seoul, Euljiro or Myeongdong for central transport and dining, or Hongdae for nightlife and a direct AREX airport connection. Gangnam is polished and convenient for COEX and the south side, but it adds substantial travel time to the historic core.
What should I book before arriving in Seoul?
Reserve Changdeokgung’s Secret Garden as soon as its booking window opens, especially for English slots and spring or autumn weekends. Also book any seasonal palace night opening, a DMZ/Panmunjeom tour if it is a priority, and KTX or SRT about a week ahead for popular weekend or holiday departures such as Seoul–Busan.
What is the best way to get from Incheon Airport to my hotel?
Take the 43-minute reserved AREX Express to Seoul Station if you are staying nearby; use the cheaper all-stops AREX for Hongdae, Mapo or intermediate stops. For Gangnam or other southern-Seoul hotels with heavy luggage, an airport limousine bus is usually easier than rail changes, though traffic means allowing 70–100 minutes.
Should I visit Seoul in spring, summer, autumn or winter?
Late April–May and late September–October are the best all-round periods for a first visit, with comfortable walking weather but higher prices and crowds. Summer is humid and rainy, especially in June–July, while winter is clear and often cheaper but genuinely cold; do not build a tight plan around Seollal or Chuseok, when transport fills and independent businesses may close.
Can I rely on the subway, or should I use taxis?
Use the subway as your default: buy a T-money card, navigate by station and neighborhood, and use Line 2 as a useful inner-city anchor. Take taxis for late nights, rain, luggage or steep final climbs, but not as your daytime default—traffic and Han River crossings can make them slower than the metro.
Is it realistic to see palaces, Gangnam and Hongdae in one day?
No—this is the classic Seoul planning mistake. Pair the palaces, Insadong and Jongno on one day, then give Gangnam or Hongdae its own late-afternoon-and-evening block; the neighborhoods are more rewarding after dark and the transfers eat time.
Do I need to rent a car in Seoul?
No. Congestion, parking and the city’s scale make a car more burden than freedom, while the metro, buses and occasional taxis cover a city break far better.
