Seoul rewards a short trip if you prioritize the right mix of old and new. Gyeongbokgung Palace anchors the itinerary, its grand gates and courtyards showing the scale of the Joseon dynasty, while the smaller, more intimate Changdeokgung Palace reveals a UNESCO-listed secret garden just steps away. Nearby, Bukchon Hanok Village lets you wander alleys of traditional wooden houses with the skyline behind them, and Insadong offers galleries, teahouses, and antique shops for a slower pace. Round it out with a stop at Gwangjang Market for legendary street food. Together these picks capture royal history, village charm, and everyday Seoul in a compact, walkable loop.
