The park’s total area is 10,850 hectares. Of this, forest land covers 9,764 hectares including 2,993.4 hectares of natural forests, 2,565.4 hectares of planted forests; and 4,205 hectares of unexploited land.
Southern Hai Van specialized forest is next to the National Forest of Bach Ma (Thua Thien – Hue Province) and Ba Na – Nui Chua natural forest. These forests form a fairly wide “corridor” for the conservation and growth of animals in danger of extinction.
Environmentally, Hai Van Pass plays an important role in making the difference between the southern (Danang City) and northern climate (Thua Thien – Hue Province), protecting Danang from the severe influences of annual storms and regulating the salination level of the Cu De River. With many historical imprints marking the Viet people’s southward movement and a grandiose landscape, Hai Van has many cultural and historical values.
