The park was established in 2004 to preserve one of the last major remnants of the Atlantic Forest in southern Brazil.
Its altitude ranges from approximately 50 to 1,100 meters above sea level.
It is home to the Southern Muriqui, one of the largest primates in the Americas and a critically endangered species.
The park contains high levels of endemism, meaning several species found here do not exist anywhere else in the world.
It helps mitigate local climate impacts by regulating water cycles in a region prone to severe flooding.
The park borders the Parque Estadual da Serra do Tabuleiro, forming a larger ecological corridor.
Parque Nacional da Serra do Itajaí is a 57,374-hectare Atlantic Forest conservation unit located in the Vale do Itajaí region of Santa Catarina. It serves as a vital corridor for biodiversity, connecting fragments of the Serra do Mar ecosystem. The park spans nine municipalities, including Blumenau, Gaspar, and Indaial, encompassing significant altitudinal gradients. It protects the headwaters of the Itajaí-Açu River basin, which is essential for regional water security. The terrain is characterized by steep, rugged topography and dense primary and secondary forest cover. It is a habitat for threatened species such as the jaguar (Panthera onca) and the brown howler monkey. Scientific research and strictly regulated ecotourism are the primary authorized activities within the park boundaries. The park is managed by the Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio).
The overlooks along the access roads in the Blumenau sector, which provide expansive views of the forest canopy and mountain ridges.
Register at the administrative office before entering trails to ensure compliance with safety protocols.
Bring specialized insect repellent, as the humid forest environment is home to various biting flies and mosquitoes.
Use professional-grade navigation tools, as signal coverage is nonexistent in most of the deep interior.
Attempting to explore off-trail areas without a local guide, as the dense, trackless vegetation and steep slopes pose a high risk of getting lost.
Access may be restricted during periods of heavy rainfall due to landslide risks; check with ICMBio before planning a visit.
Pack out all waste, stay strictly on marked paths to prevent soil erosion, and do not feed or approach local wildlife.
