The park protects the Acaraí River, one of the few water bodies on the island that still maintains high water quality standards.
Its territory contains a unique transition zone between marine, fluvial, and terrestrial ecosystems, resulting in high biodiversity.
The park includes significant archaeological sites, specifically sambaquis (shell mounds), left by indigenous populations thousands of years ago.
The restinga vegetation within the park is specifically adapted to the high-salinity and nutrient-poor sandy soils of the coastal strip.
It acts as a critical buffer zone that prevents coastal erosion and mitigates storm surges for the island's urban areas.
Parque Estadual Acaraí is a 6,667-hectare conservation unit located on São Francisco do Sul island in Santa Catarina, Brazil. It protects one of the last remaining significant expanses of Atlantic Forest and restinga vegetation in the state. The park encompasses the Acaraí River basin, expansive mangroves, and significant dune systems along the Praia Grande coastline. It serves as a vital refuge for endangered species, including the red-tailed amazon parrot and the Neotropical otter. The terrain varies from flooded fields and scrubland to dense forest corridors. Established in 2005, the park functions primarily as an integral protection area, meaning human activity is strictly regulated to prevent habitat degradation. It is not a manicured park but a rugged, wilderness-focused ecological preserve. Scientific research and controlled environmental education are the primary authorized activities within its boundaries.

Wear long sleeves and trousers to protect against high mosquito activity common in mangrove areas.
Carry all necessary water and supplies, as there are no facilities or vendors within the park boundaries.
Stick strictly to marked paths to avoid disturbing delicate, protected vegetation or encountering flooded zones.
Do not attempt to traverse the swampy mangrove sections without a local guide or proper navigation equipment.
Strictly no trash disposal; leave no trace policy enforced. Motorized vehicles are prohibited within the preserve.
