[2] Part of the banks and the length of the lake are in the park, including a large drowned forest.

The hydrography and the nature of the terrain lead to the presence of several waterfalls, water holes, and giant's kettle in the Blue River valley.

The park includes two biomes typical of New Caledonia: maquis shrubland overlying peridotite rock and tropical rainforest.

Human settlement in the park is prehistoric; petroglyphs can be found in the Blue River valley.

At the beginning of the twentieth century, forestry and chrome mining led to the development of modern transport infrastructure, much of which is still in place; there are still 36km of railways for transporting logs and ore, a traction engine winch and the Pérignon bridge, made of local wood, which crosses the branch of the lake created in the White River in 1958.
