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.

1Jamsil Sports Complex

WikipediaWeekend baseball games often sell out, and online ticketing can be difficult without Korean-language accounts.
2Changdeokgung & Secret Garden
4.7★ · 1,975outdoorClosed MonChangdeokgung was the favored residential palace of the Joseon royal family and is Seoul's UNESCO-listed palace complex. The Secret Garden is the reason to choose it when time is limited.
Secret Garden entry is capacity-controlled and tied to timed tours.
3Gyeongbokgung Palace

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.
4Yongsan & Itaewon
Yongsan gives international restaurants, Itaewon bars, Leeum Museum, and easy jumps to Namsan or the Han River. It is the city's clearest foreign-food and nightlife pocket.
5Gangnam & Seocho
Gangnam and Seocho are the high-rise south: COEX Mall, business hotels, clinics, clubs, and broad boulevards. Distances look short on maps but subway exits and crossings add time.
6Songpa & Jamsil
Songpa is the family-entertainment and sports district, with Lotte World, Lotte World Tower, Seokchon Lake, Olympic Park, and Jamsil Sports Complex clustered east of Gangnam.
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.
