2026 Sejong Hangeul Festival
A three-day Hangeul culture festival across Sejong Lake Park and Sejong Central Park, October 9–11. Official activities have different hours by zone and program; there is no single festival-wide opening time. Listings include the Hangeul Run on October 9 from 08:00–12:00 (Central Park, Ieung Bridge and the arboretum area), Hangeul play and hands-on activities, science programs, a Hangeul goods fair and water sports. The Hangeul train is paid (10:00–19:00); the Hangeul Sull-Sull traditional-liquor festival runs October 9–10, 16:00–22:00. The four programs on the official advance-booking page currently show registration closed, but that does not mean the entire festival is sold out. Check the official program page for walk-up activities and individual conditions. Scale context: In an October 1 report quoting a briefing by the Sejong City Culture and Tourism Foundation, local outlet Jungdo Ilbo reported 40 main and 42 linked programs (82 total), about 315,000 visitors in 2025, and a 2026 target of 330,000. The 330,000 figure is the organizer’s target, not an actual count. Published official listings differ on general hours: the Ministry of Culture, Sports and Tourism lists 10:00–21:00 (until 19:00 on the final day), while VisitKorea lists 11:00–21:00. Do not treat either as a settled site-wide schedule; use the official zone- and program-specific listings. The official program page lists the Hangeul Playground at Green Field (Oct 9–11, 10:00–18:00) and an urban-park horseback-riding activity across from Lake Park Parking Lot 1 (10:00–17:00). Water sports at Water-Play Island are listed separately for Oct 1–31, 10:00–18:30. Weather before you go (KMA regional bulletin, Oct 8 at 11:00): occasional clouds are forecast on Oct 9, mostly clear conditions on Oct 10 before clouds increase in the evening, and occasional clouds on Oct 11; the bulletin warns of a very large day–night temperature difference. These ranges and conditions cover the wider Daejeon/Sejong/Chungnam area, not a point forecast for the festival site. The mention of possible daytime rain on Oct 11 applies only to parts of southeastern Chungnam, not necessarily Sejong. Bring a light layer for outdoor activities and recheck the Sejong point forecast before leaving.
