The green zone of the park contains a diverse array of flora, fauna and birdlife. The endangered squirrel monkey, spider monkey, howler monkey and white-faced monkey can all see be seen here, in addition to sloths, which are found inside and outside the perimeters of the national park, iguanas, agoutis. Toucan, scarlet macaws and hummingbird are just a few of the 200 bird species found here.
The Ballena Marine National Park is worthy of a visit, fantastic for visiting turtles between July and September and bottle-nosed dolphins, as well as seasonal humpback whales from August to October and December to April.
Further south of Manuel Antonio lay the smaller village communities of Matapalo, Dominical and Uvita, with little between these except for unhurried stretches of wilderness beach.
