Baekdu-daegan
Baekdu-daegan (Korean: 백두대간; Hanja: 白頭大幹) is a traditional Korean conception of the mountains and consequently the watersheds of the Korean Peninsula. The mountain range stretches the length of the Korean Peninsula, around 1,500 km, from Baekdu Mountain in the north to Jirisan, or Hallasan on Jeju Island in the south.
