The Cabo Orange National Park covers varied ecosystems, examples of which are mangroves, natural fields, fluvial marine forests, floodable areas, and terra firm, besides rich fauna.

The natural beauties, rather well preserved and with evident tourist appeal – the case of the Cassiporé, Cunani, Uaçá, and Oiapoque – allow for boat, canoe, and launch trips and the practice of rafting.

The vast biodiversity makes possible visitation for contemplating vegetal and animal species, above all birds, in addition to projects of environmental education and scientific research (main objectives of the national parks).

The Cabo Orange National Park was created by decree 84.913 of 15 July 1980 with the objective of protecting flora, fauna and natural beauty.

[8] Protected species in the park include the giant armadillo (Priodontes maximus), giant anteater (Myrmecophaga tridactyla), jaguar (Panthera onca), oncilla (Leopardus tigrinus), black bearded saki (Chiropotes satanas), green sea turtle (Chelonia mydas), smalltooth sawfish (Pristis pectinata), West Indian manatee (Trichechus manatus) and Amazonian manatee (Trichechus inunguis).
