April peaks: azaleas & cherry blossoms
60 of Korea's 100 famous mountains are at their best or hold events in April: Biseulsan, Wolchulsan, Moaksan, Namsan (Gyeongju), Palgongsan, Geumjeongsan…
Top 10
- Biseulsan (1083m) — Biseulsan Azalea Festival: The mountain’s signature spring festival, drawing more than 300,000 people in some years. Shuttles are added and Dalseong County runs azalea tour buses in some years. / Azalea peak: From mid to late April the top turns pink. Flower weekends jam the road and the shuttle queue, so a weekday morning is better.
- Wolchulsan (811m) — Yeongam Wangin Culture Festival: Held for about four days in late March or early April. Cherry blossoms are out, so it is crowded. Check the Yeongam county site for this year's dates. / Azaleas and mountain cherry: Azaleas and mountain cherry bloom in the rock crevices, with green barley fields on the plain below.
- Moaksan (795m) — Geumsansa cherry blossom and azalea: Usually late April. The Geumsansa lot gets crowded. / Gimje Moaksan Festival: Held in early April in past years. Dates shift, so check Gimje city notices. / Gui Reservoir cherry blossom path: In spring the cherry trees arch over the loop path.
- Namsan (Gyeongju) (495m) — Azaleas: Azaleas open among the pines in early April. Shaded ridges run cooler than the village below. / Daereungwon Cherry Blossoms: A blossom event in early April that turns part of the wall lane into a pedestrian street. Come early on weekends to find parking.
- Palgongsan (1192m) — Palgongsan Cherry Blossom Road: Cherry trees form a tunnel along the road. It jams on peak-bloom weekends. / Azaleas and Apple Blossom: Late April is azalea time. The Olleh-gil walk passes apple orchards in about 2.5 easy hours.
- Geumjeongsan (801m) — Azaleas and cherry blossom on the ridge: In April azaleas and cherry blossom spread along the wall. Weekends are busy.
- Muhaksan (761m) — Azaleas around Hakbong: Colour starts in mid-April and peaks in the last week. Weekends are crowded. / Jinhae Gunhangje cherry blossom festival: In 2026 it ran from March 27 to April 5. The 2027 dates await the city announcement.
- Gwanaksan (632m) — Azaleas: Blooms in April. The higher you go the later it flowers, so the ridge near Yeonjudae opens well after the foot of the mountain. / Seoul Grand Park spring flower festival: In 2026 it ran April 4-12. A cherry lane about 800 m long, open for evening walks too.
- Unmunsan (1195m) — Spring azaleas: The Samyang route looks best in azalea season. The peak week moves from year to year.
- Geumsusan (1016m) — Azaleas: Azaleas bloom along the ridge around mid-April. / Cheongpung Lake cherry blossom festival: Performances and night movies under the blossoms. Dates shift each year, so ask the Jecheon Cultural Foundation.
