About Naejangsan
Naejangsan, on the border of Jeongeup and Sunchang, became a national park in 1971 and is Korea’s most famous autumn-colour mountain. Its small, thin-leaved maples turn a vivid red from late October into early November.
Nine peaks ring two valleys and two waterfalls, and rare evergreens such as torreya and daphniphyllum are protected here. Old geographies named it one of the five great mountains of Honam and the Diamond Mountains of the south.
From the park entrance a tunnel of 108 maples leads to Naejangsa temple.
