Yeouido Spring Flower Festival turns the cherry-tree-lined road along Yeouiseo-ro (also called Yunjungno) into one of Seoul's most photographed spring scenes, with the Han River as a backdrop.
Yeongdeungpo Lotus Lantern Festival lights up the Jongno district with traditional lanterns as part of a UNESCO-recognized intangible cultural heritage celebration tied to Buddha's Birthday. Because Buddha's Birthday follows the lunar calendar, the exact date shifts each year — confirm the current date rather than assuming it falls in the same week annually.
Jungnang Seoul Rose Festival centers on the country's longest rose tunnel (5.15km) along the Jungnangcheon stream, in full bloom during early summer.
Seoul International Fireworks Festival is the city's signature large-scale fireworks show, held over the Han River at Yeouido Hangang Park each autumn — one of the most crowded and celebrated nights on Seoul's festival calendar.
Royal Culture Festival brings Seoul's five grand palaces (including Gyeongbokgung and Changdeokgung) and Jongmyo Shrine to life with royal court reenactments and performances, marketed as Korea's largest heritage festival.
Seoul Silver Grass Festival opens Haneul Park's silvery grass fields for night viewing in autumn, combining the citys skyline views with the seasonal grass display.
Jeongdong Night Walk opens the historic cultural facilities of the Jeongdong district — dense with early modern heritage buildings — for evening exploration.
Hanseong Baekje Cultural Festival reenacts the history of Seoul as the ancient capital of the Baekje kingdom over 2,000 years ago, staged around Olympic Park.
Seoul Lantern Festival fills Gwanghwamun Square and the Cheonggyecheon stream with elaborate hanji (traditional paper) lanterns and media art installations through the coldest months.
Han River Festival runs as a rotating series of water and park-based events across all four seasons along the Han River, so there is usually some version of it happening whenever you visit.
If Seoul is your base, Agoda has hotel deals in Seoul, and Klook Seoul tours and activities are worth browsing between festivals. Since festival dates and venue changes are easiest to track with a live connection, setting up an Airalo eSIM for South Korea before you land keeps you covered.
