The Seoraksan National Park Autumn Festival celebrates peak foliage season at one of Korea’s most beautiful mountain parks in Sokcho, Gangwon Province (October 3–12). Seoraksan’s combination of granite peaks, dense forest, and dramatic valleys makes it one of the finest autumn foliage destinations in Northeast Asia — the color change typically begins at the summit in late September and works its way down through October. The festival adds cultural performances, traditional food stalls, and guided programs to the natural spectacle.
The main Seorakdong entrance area near Sokcho is the primary festival zone, with easy walking trails to iconic spots like Sinheungsa Temple, Ulsanbawi Rock, and Biryong Falls. The cable car to Gwongeumseong Fortress gives access to elevated views of the autumn canopy — the queue is long on weekends; arrive before 9AM or go on a weekday. The harder interior trails reward with far fewer crowds and equally stunning color.
