The Bukhansan National Park (Korean: 북한산국립공원; Hanja: 北漢山國立公園) in Seoul and Gyeonggi covers an area of 79.92 km2 (30.86 sq mi) and was established on 2 April 1983.

Due to its popularity with hikers and Seoul residents, some trails are closed on a rotation basis to protect the local environment.

A fortress was first built on this site in 132 AD to protect Seoul from foreign invasions, and it was expanded to its current size in 1711.

Civilians, religious leaders, other district offices, and groups, such as the Korean Mountaineering League, are assisting in the lobbying to have the name of the three original peaks reverted to Samgaksan.
