October is Seoul's best walking month, with clear air for Namsan, palace courtyards, and Bukhansan or Han River extensions.
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.

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.
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.

Food & drink
Busan food is port-city direct: dwaeji gukbap is pork-and-rice soup, milmyeon is cold wheat noodles in broth, and ssiat hotteok is a seed-filled sweet pancake sold hot from market stalls. Jagalchi Fish Market, Gukje Market, Ggangtong Market, Haeundae Market, Millak raw-fish market, and Seomyeon soup shops add eomuk fish cakes, raw fish, grilled eel, and market seafood.

Getting around
Busan Metro, light rail to Gimhae airport, buses, taxis, KTX, and ferries cover the city, with Cashbee and T-money cards accepted across most transit. Distances are long, so cluster Haeundae-Gwangalli, Nampo-Jagalchi-Gamcheon, and Beomeosa-Geumjeong as separate days.
