The grandest of Seoul's five royal palaces — the great throne hall of the Joseon kings, a pavilion floating on a lotus pond, the royal guard in scarlet at Gwanghwamun Gate and thousands of visitors in rented hanbok who walk in free. Closed Tuesdays; entry costs a few thousand won.
The UNESCO-listed palace that Joseon kings actually preferred, and behind it the Huwon, a secret garden of pavilions, ponds and old trees open only to small guided groups. Book the English tour ahead; closed Mondays.
FreeHundreds of traditional tile-roofed hanok houses climbing the hill between two palaces, with skyline views down narrow lanes. Free, but it is a living neighborhood with a visitor curfew: come between 10am and 5pm and keep your voice down.
The tower on top of Namsan mountain that every Seoul skyline photograph includes — a cable car ride up, love locks by the thousand on the terrace, and a 360-degree observatory over a city of ten million that glitters best after dark.
2-3 hours (with Namsan)$$Tickets → The highest observatory in Korea, at the top of the 555-meter Lotte World Tower — a double-decker elevator ride, a glass floor nearly 500 meters above Jamsil, and the whole Han River valley at your feet. Open late every night.
A giant indoor theme park under a glass dome plus a fairytale castle on an island in Seokchon Lake — roller coasters, parades and an ice rink, rain or shine. The best family day in Seoul, and teenagers love it in school uniforms.
A guided day to the most heavily fortified border on earth — Imjingak's Freedom Bridge, an infiltration tunnel dug toward Seoul, and North Korea through binoculars from Dora Observatory. Passport required; the JSA itself is closed to ordinary visitors.
FreeSeoul's busiest shopping district — K-beauty flagships on every corner, department stores, a neo-Gothic cathedral and, every evening, rows of food carts selling tornado potatoes, skewers and egg bread. Free to wander, easy to spend.
FreeSeoul's great traditional food market, open since the 1900s — sizzling mung-bean pancakes, mayak gimbap, raw beef yukhoe and hand-cut noodles eaten on benches at the stalls. Free to enter and the best-value feast in the city.
FreeZaha Hadid's silver spaceship of a building in the heart of the old fashion district — free to walk over, around and through, with design exhibitions inside, a city-wall park beside it and light shows on its curved skin after dark.
FreeOne of the great museums of Asia — gold crowns of Silla kings, celadon the color of jade, a ten-story marble pagoda indoors and the serene Pensive Bodhisattva room. Free permanent galleries for now, with paid entry expected from 2027.
FreeWhere Seoul goes to breathe — twelve riverside parks with bike paths, picnic lawns, rainbow fountains, ferries and the beloved ritual of instant ramyeon and fried chicken delivered to your mat at sunset. Free and open around the clock.
