Korea Autumn Foliage

Fall colors move south from late September to mid-November. Seoraksan and northern mountains peak first (late September-early October). Central regions including Seoul follow (mid-October-early November). Southern areas like Naejangsan peak last (late October-mid November). Temperature drives the timing. Cool nights and warm days produce the best colors. A sudden early frost can accelerate or damage the display. Check foliage forecasts (단풍 예보) updated weekly by the Korea Meteorological Administration. Mountains peak before lowlands. A mountain summit might peak two weeks before its base. This extends viewing opportunities—you can chase peak color by adjusting elevation. Maple trees (단풍나무) provide the iconic reds. Ginkgo trees (은행나무) offer bright yellow. Mixed forests create the most dramatic displays. Urban areas with planted trees have more uniform but less varied color. Weekends during peak season are intensely crowded at famous spots. Weekday visits, especially Tuesday-Thursday, offer dramatically better experiences at popular destinations.

Seoraksan National Park in Gangwon-do has Korea's most famous fall scenery. The rocky peaks contrasting with blazing maples draw massive crowds. Osaek area and Biryong Falls are highlights. Peak: late September-early October. Naejangsan National Park in Jeollabuk-do is specifically famous for foliage—the name means 'hidden inside mountains.' The tunnel of maple trees approaching the temple is Korea's most photographed autumn scene. Peak: late October-early November. Nami Island transforms in autumn, with metasequoia-lined paths and lakeside maples. Popular year-round but spectacular in fall. Weekdays are essential. Peak: late October. Gwanaksan in Seoul offers accessible mountain foliage without traveling far. The ridge walk provides city views through autumn colors. Peak: late October-early November. Changdeokgung Palace's Secret Garden (Huwon) combines autumn colors with Korea's finest traditional garden. Guided tours only, book in advance during peak season. Peak: late October-mid November.

Daedunsan Provincial Park straddles North and South Chungcheong provinces. The suspension bridge connecting rocky peaks above autumn forest is dramatic and less visited than famous parks. Peak: late October. Juwangsan National Park in North Gyeongsang offers waterfalls, rock formations, and fall color without Seoraksan's crowds. The valley walk to Yongchu Falls is superb. Peak: mid-late October. Mudeungsan near Gwangju combines accessible hiking with dramatic columnar rock formations. Fall colors backdrop the distinctive volcanic pillars. Peak: late October-early November. Baekdamsa Temple approach in Seoraksan's less-visited inner section rivals the main peaks. The 8km walk from Yongdae-ri follows a stream through forest. Peak: early October. Songnisan National Park hosts Beopjusa Temple, where a 33-meter Buddha statue rises above autumn trees. Less crowded than comparable temple-mountain combinations. Peak: late October.

Book accommodations early. Popular areas like Seoraksan and Jirisan sell out weeks ahead during peak season. Temple stays (templestay.com) are excellent alternatives. Start early. Famous viewpoints get crowded by mid-morning on weekends. Dawn photography requires arriving before sunrise. Layer clothing. Autumn mornings are cold (sometimes near freezing in mountains), but midday sun can be warm. Temperature swings of 15°C are common. Bring proper shoes. Wet leaves on mountain trails are slippery. Good hiking footwear is essential for mountain destinations. Check closure dates. Some mountain areas close sections during fire-prevention periods in spring and fall. Verify access before traveling. Consider temple stays. Waking up at a mountain temple surrounded by fall color, joining morning chanting, and hiking empty trails before day visitors arrive is incomparably better than fighting traffic.
