The Santa Rosa do Purus National Forest is in the municipality of Feijó in the state of Acre.

The Santa Rosa River, which defines the border between Brazil and Peru in this region, flows in a north east direction some distance to the south of the park and then forms the boundary for a short distance until it joins the Purus River, which then forms part of the boundary before flowing north east towards Manoel Urbano.

[1] On 23 August 2006 the Instituto Nacional de Colonização e Reforma Agrária (National Institute for Colonization and Agrarian Reform, INCRA) recognised the forest as an agro-extraction project for 35 families.

The national forest covers about 7,250 hectares (17,900 acres) of the Riozinho do Alto Envira Indigenous Territory.

Use of forest resources, scientific research and public visits would only be allowed by agreement between Fundação Nacional do Índio (National Indian Foundation) and ICMBio.
