Seoul

Seoul is a city of thrilling contrasts, and it makes the juggling act look effortless. In a single afternoon you can wander a 600-year-old royal palace, browse a neighborhood of centuries-old hanok houses, then ride one of the world's slickest subways to a district glowing with skyscrapers and giant screens. South Korea's capital is fast, fun, endlessly hospitable, and far more layered than its high-tech reputation lets on. History anchors the city. Gyeongbokgung, the grandest of Seoul's five royal palaces, is the essential first stop, and catching the changing of the guard ceremony is worth timing. Right beside it, the Bukchon Hanok Village preserves lanes of traditional tiled-roof homes, and renting a hanbok (traditional dress) to stroll through, and often to gain free palace entry, has become a beloved ritual. Nearby Insadong is the place for tea houses, calligraphy, and crafts. Then Seoul flips the switch to the future. Myeongdong is a neon-lit maze of skincare shops and street food, Dongdaemun buzzes with all-night shopping and Zaha Hadid's spaceship-like Design Plaza, and Gangnam (yes, that one) gleams with upscale style south of the river. For the classic city panorama, ride up to N Seoul Tower on Namsan Mountain, where couples fasten love locks along the railings. Food might be the best reason to come. Sizzle your own Korean barbecue, slurp spicy tteokbokki from a street cart, dig into bibimbap and cold naengmyeon noodles, and don't skip a late-night session of fried chicken and beer, the combo locals affectionately call chimaek. Markets like Gwangjang and Namdaemun are edible adventures in their own right. Seoul rewards curiosity in every direction: hike the fortress walls of Bukhansan for mountain views over the metropolis, explore the youthful, artsy streets of Hongdae, or take a sobering, fascinating day trip north to the DMZ separating the two Koreas. Getting around is a genuine pleasure. The subway is clean, cheap, extensive, and signed in English, and a rechargeable T-money card works on subways, buses, and even in convenience stores. It's easily one of the best transit systems anywhere. The Korean won is the currency, and Seoul spans every budget, from street-food feasts to luxury shopping. Spring (cherry blossoms) and autumn (crisp air and fall colors) are the loveliest seasons. Give the city four or five days, and it still won't feel like enough.
