Destination & City Travel Guide
About Seoul
Seoul rewards a district-by-district plan. Gyeongbokgung Palace and Bukchon frame a day around older streets, while Myeongdong and Hongdae show different sides of its shopping and café culture. The Han River provides walking and cycling space between built-up neighbourhoods. Incheon International Airport lies west of the city on an island; its rail link makes Seoul Station a useful first point for many visitors arriving from India. Check the final metro connection before choosing a late arrival.

What's new in Seoul
May 2025: Photography Seoul Museum of Art opened, adding a dedicated photography venue to the city’s museum choices.
January 2026: Asiana Airlines moved from Incheon Terminal 1 to Terminal 2, changing the airport building and rail stop used by its passengers.
Tips for travellers from India
Hongdae is useful for an airport-rail arrival and an evening in its surrounding streets, while Myeongdong puts central shopping closer. A palace-focused stay can favour the Jongno area instead. The Airport Railroad’s express and stopping trains serve different purposes: the express links the airport with Seoul Station, while stopping services reach additional interchanges. Choose according to the hotel district.
Asiana moved to Terminal 2 on 14 January 2026, so older guides that send its passengers to Terminal 1 are out of date. Incheon’s official app and flight information identify the correct terminal before a return train ride. Gyeongbokgung and Bukchon belong together geographically, but Bukchon includes residential lanes and should be approached as a lived-in neighbourhood. Hongdae is a separate western outing rather than the next stop on a palace walk. The Han River also has many access points; select a particular riverside park instead of navigating to the river in general. That choice determines the useful metro station and prevents an unnecessary crossing of Seoul.
Best time to visit Seoul
April to May or September to October, about 10–24°C, for outdoor districts.
