It is among the largest urban nature reserves globally, significantly exceeding the size of the Tijuca National Park.
The park contains the highest peak within the municipality of Rio de Janeiro.
It protects several endangered animal species, including the woolly spider monkey and the jaguarundi.

It encompasses several traditional communities, known as quilombos, within its protected boundaries.
Parque Estadual da Pedra Branca is one of the world's largest urban forests, covering approximately 12,500 hectares of Atlantic Forest in Rio de Janeiro. The park features diverse mountainous topography, reaching its highest point at Pico da Pedra Branca with an elevation of 1,024 meters. It serves as a critical environmental conservation unit protecting the watersheds of the Jacarepaguá, Guaratiba, and Campo Grande basins. The terrain is characterized by dense tropical vegetation and rocky outcrops, offering numerous trails for hiking and trekking. Unlike some smaller urban parks, the area maintains a high level of biodiversity, including rare species of flora and fauna endemic to the Atlantic Forest. It functions as a natural barrier regulating the microclimate of the western zone of Rio de Janeiro. The park is managed by the State Institute of the Environment (INEA) and includes several distinct entrance sectors for public access.
