Seongsan Bridge, a prominent Han River crossing in Seoul, South Korea, offers scenic views, particularly at night when its distinctive truss structure is illuminated. Accessible via public transportation (buses and nearby subway stations connecting to the Han River parks), it's ideal for a solo visit or as part of a larger exploration of the Han River's recreational areas like Mangwon Han River Park. There are no seasonal restrictions, though evening visits during temperate weather are most pleasant. The bridge itself is free to access, with a typical visit duration of 15-30 minutes for a stroll or photo stop, extending if combined with activities in the adjacent parks. It's best experienced as a picturesque backdrop or a point of transit across the river, rather than a standalone destination.
