Bukhansan Mountain is situated in the northern part of Seoul. Designated as a national park in 1983, the mountain is 78.45km wide and has 6 districts and extends out into Gyeonggi-do. The name Bukhansan means "big mountain in the north," and it is also called Samgaksan Mountain. Bukhansan Mountain has such smooth curves that the large granite rocks sometimes look as if they would slide down the mountain. The sharp peaks provide contrast to the dozens of valleys and rivers flowing below. The mountain has many different kinds of peaks but its main peak is Baegunbong. The granite peaks blend well with trees, and there are about 1,300 kinds of animals and plants living on the mountain. Among the granite peaks, the best known is Insubong Peak’s Giam rocks. The world famous granite rock peak Insubong is over 200m above sea level, and there are about 100 mountain paths leading to the rock. When you stand on Baegundae and look down, sometimes you can see as far as Seoul City.
