The APA covers a significant portion of the largest continuous stretch of Atlantic Forest remaining in Brazil.
It contains the Ilha do Cardoso, a research-heavy island known for its well-preserved marine and terrestrial ecosystems.
The estuary system here is a nursery for various fish and crustacean species crucial to the local maritime economy.
Sambaquis found within the park provide evidence of human occupation dating back thousands of years.
The region is a primary research hub for scientists studying the behavior of the endangered Guiana dolphin.
The landscape includes unique 'restinga' vegetation, which is specifically adapted to sandy, nutrient-poor coastal soils.
The Área de Proteção Ambiental (APA) de Cananéia-Iguape-Peruíbe is one of the largest protected coastal areas in Brazil, spanning over 200,000 hectares of Atlantic Forest and marine ecosystems. It serves as a vital transition zone between tropical and subtropical biomes, encompassing mangroves, restingas, and coastal islands. The preserve is a critical sanctuary for the Guiana dolphin, locally known as the boto-cinza, which inhabits the surrounding estuaries. Its topography includes mountain ranges reaching over 1,000 meters, descending directly toward the Atlantic coastline. Archaeological sites known as sambaquis, which are ancient shell middens created by indigenous coastal populations, are located throughout the preserve. The area is part of the Atlantic Forest Biosphere Reserve, designated by UNESCO for its immense biological diversity. Waterways within the APA facilitate transit between the coastal towns of Cananéia, Iguape, and Ilha Comprida. The region experiences high rainfall, which sustains a dense, multi-layered forest structure that supports numerous endemic bird and mammal species.
The elevated lookout points in the Serra do Mar section provide expansive views of the coastline and mangrove canopy.
Bring high-quality insect repellent, as the humid mangrove environment is home to significant midge and mosquito populations.
Hire a local boat captain registered with environmental authorities to safely navigate the complex estuary channels.
Wear lightweight, quick-drying clothing and sturdy waterproof footwear suitable for muddy coastal paths.
Attempting to explore the mangrove trails without a local guide or proper GPS equipment, as the waterways can be labyrinthine and disorienting.
Practice strict Leave No Trace principles; strictly forbidden to feed wildlife or remove any organic matter including shells or rocks.
