Vegetation Luxuriant and varied due to the wide range of altitude. Lower levels have tropical rain forest rich in lianas, ferns and epiphytes (including orchids and bromeliads). The upper slopes have montane grasslands, a notable species being the endemic Prepusa hookeriana (Gentianaceae) which occurs on the peak of Pedro do Sino. Brush and small trees occur in sheltered areas in the montane zone, the trees being covered with lichens and mosses.

The La Plata otter Lutra platensis (V) has also been recorded, and the woolly spider monkey Brachyteles arachnoides (E) possibly still occur here, but the buffy-tufted-ear marmoset Callithrix aurita (E) now appears to have disappeared from the park.
