It protects an important but relatively unexplored region of rainforest with bamboos holding great biodiversity.

The headquarters may be reached by boat from Manuel Urbano or by charter float plane from Rio Branco.

The Cuchicá forms the northern border of the park to the point where it joins the Chandless.

Aspects of natural beauty include dry ravines 15 metres (49 ft) deep, rocky outcrops, small rapids and sandy beaches.

It adjoins protected areas and indigenous territories on the Peruvian side where rare and endemic species have recently been found.

The nearby municipalities still have more than half of their settlement capacity unused, and the park is difficult to access during dry periods.

When the park was formed there were 12 families in the area with about 60 people engaged in activities that have little impact on the environment.
