The park protects one of the largest remaining contiguous areas of Atlantic Forest in Brazil.
It houses the Ilhabela archipelago, which consists of over 10 islands and islets.
The park's altitude ranges from sea level to over 1,300 meters, creating diverse microclimates.
Several trails lead to hidden coastal waterfalls that flow directly onto sandy beaches.
The park is home to the 'borrachudo' (black fly), a small insect known for its persistent bite, requiring specific insect repellent use.
It contains historical ruins from early 20th-century sugarcane and coffee farming attempts.
The park's maritime area is regulated to protect coral reefs and migratory marine mammals.
Parque Estadual Ilhabela encompasses 83% of Ilhabela island, covering approximately 27,025 hectares of preserved Atlantic Forest. The park features a rugged coastline characterized by sharp mountain slopes that drop directly into the Atlantic Ocean. It contains over 360 waterfalls and several high-altitude peaks, including Pico de São Sebastião at 1,374 meters. The park serves as a critical biodiversity corridor for endemic species, including various bromeliads and rare bird populations. Its territory includes complex hiking trails ranging from coastal paths to challenging mountain treks. Access to specific remote beaches and waterfalls often requires navigation of steep terrain or boat transit. The environment is categorized as a protected conservation unit, emphasizing the preservation of the Mata Atlântica biome. It remains the largest protected maritime state park in the state of São Paulo.
