[1] The park forms the central region of the Serra de Paranapiacaba Mosaic, which has over 120,000 hectares (300,000 acres) and contains the largest remaining area of Atlantic Forest in Brazil.

In the municipality of Sete Barras the terrain is still mostly mountainous but has extensive floodplains, with altitudes from 80 to 900 metres (260 to 2,950 ft).

Towards the center of the park, where the Serra de Paranapiacaba forms the watershed between the Ribeira do Iguape and Paranapanema basins, more of the flora belong to seasonal semi-deciduous forest.

It includes four lodgings with a capacity of 100 guests, a restaurant, an environmental monitoring center, soccer fields, a playground, housing for researchers and staff residences.

From the headquarters there are short and medium-length trails that give access to waterfalls, caves and belvederes, with stretches of forest in a good state of conservation.

The Chapel of Santo Inácio e Encanados on the border with the Xitué Ecological Station is of historical and cultural interest.
