The Seokchon Lake Cherry Blossom Festival is Songpa-gu's free spring festival around Seokchon Lake, beside Lotte World Tower in south-east Seoul, where about 1,000 king cherry trees line a lit lakeside path of about 2.5 km. The 2026 edition ran 3–11 April; the 2027 dates follow the bloom and are expected between late March and mid-April, announced only about ten days ahead.
The Yeouido Spring Flower Festival is Yeongdeungpo-gu's free cherry-blossom festival on Yeouiseo-ro (Yunjung-ro), a 1.7 km riverside road behind the National Assembly in Seoul that closes to cars for about a week and is lined with about 1,886 cherry trees, lit after dark. The 2026 edition ran 3–7 April, 11:30–21:30; the 2027 dates follow the bloom forecast and are expected in late March or the first half of April, not yet announced.

The Changdeokgung Moonlight Tour (창덕궁 달빛기행) is a ticketed, guided night walk by lantern light through Changdeokgung Palace and its Secret Garden in central Seoul, with a daegeum flute solo, court dance, and tea with traditional sweets. It runs in spring and autumn: the autumn 2026 season ended on 17 October, and no 2027 dates had been announced as of 19 October 2026 (recent spring seasons have started in mid-April).
Yeon Deung Hoe is Seoul's Buddhist lantern festival for Buddha's Birthday (8th day of the 4th lunar month). Its centrepiece is a free Saturday-evening parade of about 100,000 lanterns from Heunginjimun along Jongno to Jogyesa Temple, with lantern exhibitions at Jogyesa, Cheonggyecheon and Bongeunsa.
April is cherry-blossom month. Jinhae's festival ends in the first days of April, and in Seoul the cherry trees bring festivals to Yeouiseo-ro behind the National Assembly on Yeouido and to Seokchon Lake beside Lotte World Tower, both timed to the bloom in late March or the first half of April, as are Gyeongju's stone-wall road at Daereungwon and the canola fields along Noksan-ro on Jeju. Mid-April brings azaleas on Biseulsan in Daegu and the start of three weeks among the green barley at Gochang, and Taean's tulip festival on the west coast runs from early or mid April into the first week of May, with the blooms usually at their best in mid to late April. Daejeon's science festival has been held in mid-April in recent years, and Jindo's sea road opens when the tides are lowest. The last week starts a run into May with the Hampyeong Butterfly Festival, the Jeonju International Film Festival and the Namwon Chunhyang Festival, and the lotus-lantern season begins in Seoul ahead of Buddha's Birthday, with the Yeon Deung Hoe parade on a Saturday in late April or May.
Tip. April weekends are the busiest of the spring for domestic travel; weekday visits are far calmer.
