[1] The specific objectives of the park are the preservation of various Amazonic ecosystems, through scientific, educational and recreational means.

The habitat is dense lowland rain forest and there are areas of white-sand grasslands beside the upper reaches of the Tapajós.

This river rises in the Precambrian crystalline shields area of ancient igneous rock and carries little sediment.

[2] To the west the park adjoins the 827,877 hectares (2,045,730 acres) Pau-Rosa National Forest, created in 2001.

[4] The proposed South Amazon Ecological Corridor would link the park to other protected areas and indigenous territories in the region.

The larger trees reach a height of about 50 m (160 ft), and the light filtering through the canopy is sufficient to produce a biodiverse understorey of vines, lichens, mosses and orchids.
