not just a site of environmental protection, the parque estadual da ilha grande was also listed by the state institute of cultural heritage (inepac) in 1987, and then, in 1991, the park was recognized by unesco as a biosphere reserve of the atlantic.

due to the status of the park, there are a number of restrictions of conduct within its borders, including the prohibition of cutting trees, plucking seedlings, feeding or chasing animals, farming, hunting, fishing in the rivers, extraction mining of any kind, and commercial or industrial occupancy.

located on the exotic ilha grande island, the park is just off the coast of the state and easily accessible from rio de janeiro city.
