Three days in Seoul provides a solid introduction to modern neighborhoods, ancient palaces, and street markets. Careful planning is essential so you do not spend your short trip stuck on transit.
Getting into the city from Incheon Airport
Most international travelers land at Incheon International Airport (ICN). The AREX Express Train is the fastest airport connection, taking 43 to 45 minutes direct to Seoul Station.
If your hotel sits near Hongik University or Gimpo Airport, the AREX All-Stop Train makes 10 to 13 stops and takes 56 to 60 minutes. Airport Limousine Buses offer direct drops to hotel districts in 60 to 90 minutes, while taxis take around an hour depending on traffic.

Understanding transit and ticket costs
A T-Money card is indispensable for riding subways, local buses, and taxis. Base subway and bus fares drop to ₩1,500-₩1,550 with a T-Money card, compared to ₩1,600-₩1,650 for single-use paper tickets. T-Money also unlocks free transfers between subway and bus lines within 30 minutes.
Buy the physical card for ₩4,000 to ₩5,000 at convenient airport stores, then load cash credit. A starting balance of ₩50,000 easily covers transit and quick market purchases for three days. Standard taxis charge a base fare around ₩4,800 for the first 1.6 km, but remember that a 20-40% surcharge applies late at night between 10 PM or 11 PM and 4 AM.
Palace schedules, observation decks, and timing
Palace visits require attention to weekly closure days. Gyeongbokgung Palace is closed every Tuesday, while Changdeokgung and Deoksugung close every Monday. Entry to Gyeongbokgung is ₩3,000 for adults, or completely free if you wear a rented hanbok (traditional Korean clothes).
The Secret Garden (Huwon) inside Changdeokgung Palace requires booking online six days ahead for half the entry slots, while remaining spots open at the ticket office on the day of your visit. For N Seoul Tower, adult observatory tickets run ₩23,400 to ₩29,000, and arriving an hour before sunset helps avoid peak queue delays.
Crucial mistakes and entry requirements
Never rely solely on Google Maps, which has restricted functionality in South Korea. Download local apps like Naver Map or KakaoMap for accurate train routing and walking directions. Always remember to tap out your T-Money card when exiting vehicles to keep your transfer discounts intact.
