Sanmasil🍁 Korea Autumn Foliage Forecast 2027 — Peak Dates by Mountain
Fall colors start in the high mountains of the north in late September and reach the south coast by mid-November. Here is the usual peak for each mountain, estimated from long-term weather averages and adjusted for latitude and height.
📅 Rule of thumb: Seoraksan and Odaesan peak in mid–late October, Seoul’s mountains in late October to early November, and Naejangsan and Jirisan’s southern slopes in early–mid November. Each year can be 1–2 weeks earlier or later.
