The Banpo Bridge Moonlight Rainbow Fountain in Seoul offers a stunning, free-to-view spectacle over the Han River, best enjoyed from Banpo Hangang Park. It's easily accessible via subway and a short walk, with the park being generally accessible for all. This attraction is ideal for solo visitors or groups, requiring no guided tour to appreciate its beauty, though Han River cruises offer a different perspective. The fountain operates seasonally from April to October, with specific evening show times; visitors should always check the latest schedule online, as shows are cancelled in winter and may be affected by weather. A typical visit to witness the fountain show lasts about 30-60 minutes, though many choose to extend their stay by picnicking or strolling in the park. For the best experience, arrive early to secure a good viewing spot, especially on weekends.
