About Seoul
City overview
Seoul is a Han River capital split between Gangbuk, the Joseon-era north with palaces and markets, and Gangnam, the newer south with towers, malls, and business districts. The city has no single tourist centre: Jongno and Jung carry Gyeongbokgung, Bukchon, Myeongdong, Namdaemun, and Namsan, while Hongdae, Itaewon, Gangnam, and Songpa each behave like their own downtown.
Food & drink
Seoul is built around barbecue, soups, and late-night snacks: samgyeopsal, bulgogi, bibimbap, tteokbokki, Korean fried chicken, dakgalbi, bingsu, and gimbap all have easy first-trip versions. Myeongdong and Gwangjang Market are central snack anchors, Hongdae and Sinchon run late, Itaewon handles international food, and Michelin Bib Gourmand-style pricing sits beside expensive Gangnam tasting counters.

Lotte World Tower & Seoul Sky
4.6★ · 6,256outdoorOpen dailyThe 555.7-metre, 123-story tower opened in 2017 in Songpa and is South Korea's tallest building. Check the weather before paying for Seoul Sky because haze and rain flatten the view.
2Olympic Park
4.6★ · 3,006outdoorOpen dailySongpa's Olympic Park was built for the 1986 Asian Games and 1988 Seoul Olympics, with lawns, lakes, sculpture spaces, stadiums, and the SOMA Museum. The Hanseong Baekje Cultural Festival usually takes place here in September.

3Namsan Seoul Tower
4.5★ · 66,883outdoorOpen dailyNamsan rises above Jung with the Seoul Tower at its summit, giving the cleanest central-city view across both palace core and Gangnam skyline. It pairs naturally with Myeongdong or Namdaemun rather than a separate taxi trip.

Neighborhoods
1Jongno
Jongno is the Joseon core, with Gyeongbokgung, Changdeokgung, Bukchon, Insa-dong, Gwanghwamun, and Cheonggyecheon arranged for heavy walking days.
2Jung, Myeongdong & Namsan
Jung mixes Seoul Station, Myeongdong shopping, Namdaemun Market, Deoksugung, and Namsan. It is convenient but crowded, especially at street-food and cosmetics hours.
3Seodaemun, Mapo & Hongdae
Mapo and Seodaemun are university-driven, with Hongdae, Sinchon, Hapjeong, indie music venues, clubs, cafes, and World Cup Stadium on the western map.
Day trips
55km / full-day guided tour from central Seoul
DMZ and Panmunjeom area
The Demilitarized Zone is the cold-war day trip north of Seoul, but access changes with security conditions and many sites require a tour operator. Check which areas are open before booking.
30km / about 1h by Subway Line 1 from Seoul
Suwon Hwaseong Fortress
Suwon is the easiest UNESCO half-day, with Hwaseong Fortress walls, gates, and old-town food streets. It works by subway without a tour.
35km / about 1h by Seoul Subway Line 1 or AREX connections
Incheon
Incheon adds Chinatown, the open-port history area, Wolmido, and airport-side logistics to the Seoul region. It is better as a slow waterfront day than a rushed stop before a flight.
Getting around
Seoul Subway lines cover nearly every visitor district, and T-money cards work across subway, buses, taxis, and convenience stores. AREX links Incheon Airport to Hongdae and Seoul Station in about an hour, while palace-core days are fastest by walking between Gwanghwamun, Bukchon, Insa-dong, and Cheonggyecheon rather than re-entering the subway for one stop.
