Seoul’s event calendar is packed year-round, mixing centuries-old traditions with cutting-edge pop culture. Here’s the complete lineup organized by season, with dates, locations, and what to expect at each event.
Seoul Events and Festivals: Spring (March to May)
Yeouido Spring Flower Festival
Early April (typically April 1-10, exact dates announced in March). The best-known cherry blossom festival in Seoul takes place along Yunjung-ro, a 1.7km road behind the National Assembly Building on Yeouido Island. Over 1,800 cherry trees form a tunnel of blossoms. Street performers, food stalls, and evening illuminations run throughout the festival period. Free entry. Extremely crowded on weekends; go at 7 AM on a weekday for photos without crowds. Yeouinaru Station, Exit 1.
Buddha’s Birthday (Seokga Tansinil)
Eighth day of the fourth lunar month (usually May). All temples across Seoul hang colorful lotus lanterns, and the main event is the Lotus Lantern Festival (Yeon Deung Hoe) with a parade of 100,000 lanterns from Dongguk University to Jogyesa Temple along Jongno. The parade runs 7-9:30 PM on the Saturday before Buddha’s Birthday. Free to watch from the sidewalk. Jogyesa Temple in Insadong becomes a sea of lanterns worth visiting any evening during the week leading up to the holiday. Temples offer free bibimbap meals to all visitors on the holiday itself.
Seoul Fashion Week
March and October (twice yearly). Held at Dongdaemun Design Plaza (DDP), Seoul Fashion Week showcases Korean designers and has become a significant date on the global fashion calendar. The main runway shows are industry-only, but the surrounding events including pop-up shops and street fashion photography around DDP are open to the public. Free to observe from the public areas; the DDP exterior becomes a gathering point for fashion photographers and influencers.
Seoul Events and Festivals: Summer (June to August)
Boryeong Mud Festival
Mid-July (two weeks). While not technically in Seoul (two hours south by KTX or express bus), Boryeong Mud Festival is the most famous summer event accessible as a day trip. Daecheon Beach transforms into a mud wrestling, mud sliding, and mud painting party zone. The mud is actually mineral-rich clay shipped from Boryeong’s mud flats. Entry to the festival zone costs about 12,000 KRW (US$9) for adults. KTX trains from Yongsan Station to Daecheon take about 2 hours; book tickets in advance during festival weeks. Accommodation in Boryeong sells out months ahead; a day trip from Seoul is the practical option.
Seoul International Fireworks Festival
Early October. Held at Yeouido Hangang Park, this is Seoul’s largest fireworks display. Teams from South Korea, Japan, the US, and European countries compete with elaborate fireworks shows synchronized to music. Over 1 million spectators line the Han River banks. The best viewing spots are Yeouido Hangang Park (arrive by 3 PM for a good spot) and the less-crowded Nodeul Island. Free. Bring a picnic mat and arrive early. Traffic around Yeouido is gridlocked so use the subway.
Seoul Events and Festivals: Autumn (September to November)
Chuseok (Korean Thanksgiving)
15th day of the 8th lunar month (varies annually, typically September/October). Chuseok is Korea’s most important holiday, a three-day harvest festival when Koreans return to their hometowns. Seoul becomes noticeably quieter as millions leave the city, making it an excellent time to visit attractions without crowds. However, many small restaurants and shops close. The palaces offer free admission during Chuseok and host traditional folk games (ssireum wrestling, tuho arrow throwing). The National Museum of Korea runs special Chuseok programs. Intercity transport is booked solid before and after the holiday; stay in Seoul during the three-day window.
Seoul Lantern Festival
First two weeks of November. One of Seoul’s signature events, the lantern festival stretches 1.2km along Cheonggyecheon Stream from Cheonggye Plaza to Supyo Bridge. Each year has a different theme, with hundreds of elaborate lantern sculptures illuminated along the water. Free admission. Evenings 5 PM to 10 PM are the best time to visit when the lanterns are lit. Weekends are extremely crowded; visit on a Tuesday or Wednesday evening. Gwanghwamun Station or Jonggak Station.
Seoul Events and Festivals: Winter (December to February)
Christmas and Year-End Festivities
December 1 to January 15. While South Korea is not a Christian-majority country, Christmas is celebrated enthusiastically as a commercial and romantic holiday. The Cheonggyecheon Stream gets a Christmas lights display. Lotte World holds a Christmas-themed indoor parade and outdoor ice rink (open December through February, 13,000 KRW including skate rental). Myeongdong shopping district puts up elaborate light decorations. The Myeongdong Cathedral holds popular Christmas Eve masses. Hotel restaurants offer Christmas buffets (book weeks ahead). New Year’s Eve sees the Bosingak Bell ringing ceremony at Jonggak, a tradition dating to the Joseon era; arrive by 10 PM for a spot.
Hwacheon Sancheoneo Ice Festival
Three weekends in January. About three hours northeast of Seoul in Gangwon Province, Hwacheon hosts Korea’s largest ice festival on a frozen river. The main activity is bare-handed trout fishing through holes cut in 40cm-thick ice (15,000 KRW). Your catch can be grilled on-site. The festival also features ice sculptures, snow sledding, and ice soccer. Shuttle buses run from Seoul (3 hours, about 20,000 KRW round trip, book via the festival website). Daytime temperatures typically range -5degC to 3degC (23-37degF); dress in full winter expedition gear. Weekends are extremely crowded with families.
Seollal (Lunar New Year)
First day of the lunar calendar (late January or February). Like Chuseok, Seollal is a family holiday when Seoul empties out. The palaces offer free admission and run traditional game programs (yutnori, neolttwigi, jegichagi). The National Folk Museum hosts the largest Seollal celebration with performances, food, and folk games for families. Wearing hanbok is common for palace visits during Seollal. Many restaurants in central tourist areas remain open, but local neighborhood spots close. Intercity buses and trains are fully booked.
