Naejangsan is also called Geumgang of Honam and renowned as one of the 8 views in Joseon. It is also selected as 5 noted mountains in Honam along with Jirisan (Mt.) in Namwon, Wolchulsan (Mt.) in Yeongam, Cheongwansan (Mt.) in Jangheung, Neunggasan (or Byeonsan (Mt.)) in Buan according to Dongguyeojiseungnam (東國輿地勝覽). Traditional view of mountain ranges such as Baekdu Daegan and Honam-jeongmaek are based on the watershed which divides water systems of rivers. In light of this view, Noryeong mountain range falls under Honam-jeongmaek.
Naejangsan, located in Honam-jeongmak is in a very important position in that respect because it is a watershed which divides into 3 rivers - Dongjin, Hwangnyong, Seomjin - with Ibamsan (Mt. 626m) on the west, Baegamsan (also called Baekhaksan Mt. 700m) on the south.
The north slopes of Naejangsan and Ibamsan become the upper stream of Dongjingang (River). The south slopes of Ibamsan and Baekhaksan flow into Hwangnyongang (River), that of Yeongsangang (River) and the east slopes of Naejangsan and Baekhaksan (a part of Bokheung-myeon, Sunchang-gun) become that of Seomjingang (River).
The ridge connected from Bangjangsan (Mt.) on the west of Galjae, where the name derived from, to Baegamsan, which is at the back of Ibamsan and Baegyangsa (Temple) on the east of it, is also bordered between Jeollabuk-do and Jeollanam-do.
Naejangsan was designated as a national park with Baegyangsa (Temple) district in the vicinity on November 11, 1971. Naejangsan national park with the total area of up to 76.032km2 covers 43.8km2 in Jeollabuk-do and 32.232km2 in Jeollanam-do, ranging from Jangseong-gun in Jeollanam-do, Sunchang-gun, and Jeongeup-si.
