Korea is entering one of its most colorful seasons as autumn foliage spreads across mountains and parks. Unlike spring flowers, which usually bloom first in warmer southern areas, autumn leaves change color earlier in colder places. As temperatures fall, the green chlorophyll in leaves breaks down, allowing other colors such as yellow, orange, and red to appear.

Because of this, Korea’s foliage season usually begins in northern regions and at higher elevations. This year, Seoraksan is expected to reach its peak around October 25th. Bukhansan in Seoul may show its best colors around November 4th, while Naejangsan and Hallasan are expected to reach their peak in mid-November.

Seoraksan is one of the first major destinations to reach peak foliage. Its steep rock formations rise above forests that blaze with warm autumn colors. When the forests around its cliffs and deep valleys turn red and gold, the mountain offers one of Korea’s most dramatic autumn landscapes.

As the changing colors approach the capital, Bukhansan becomes a convenient choice for Seoul residents. Visitors can follow wooded trails, hear dry leaves crackle under their feet, and look down at the city from ridges surrounded by autumn scenery. The mountain offers a refreshing escape without requiring a long trip.

Later in the season, Naejangsan draws visitors with its brilliant maple leaves. The mountain is famous for tree-lined paths that create tunnels of red and orange. Around temples and walking trails, the scenery becomes especially peaceful, making it a favorite destination for late autumn.

However, peak foliage can be brief and easily affected by the weather. Rain, strong winds, or sudden cold snaps can quickly change the view, so visitors should check forecasts before planning their trips.
