Korea's most spectacular autumn foliage season, centred on Seoraksan National Park where the mountain's granite peaks turn amber and crimson from early October. The festival week includes traditional performances, night trail access, and photography contests. Weekends in peak colour (typically second week of October) draw massive crowds — arrive at the park gate before 7 AM or book Osaek village accommodation to access trails before tour buses arrive.
