Purchase of the land making up this park is currently underway. Most of the park consists of evergreen primary forest, very high and with great species diversity. Together with the Golfito Refuge, it forms the southeast end of the ecological arc that surrounds Dulce Gulf and which begins in Corcovado National Park.
The forest consists of three levels, with trees up to 40 or 50 m high like the predominant espave (Anacardium excelsum), silk cotton tree (Ceiba pentandra) a giant that can reach up to 70 m, wild fig (Ficus namensis) and cotonron (Luehea seemannii). The species typical of the middle layer are guavas (Inga) and chapernos (Lonchocarpus). In the undergrowth, there are lots of heliconias (Heliconia), sahinillos (Dieffenbachia), bijaguas (Calathea) and palms like the royal palm (Atalea butyracea) and the viscoyol (Bactris).
The animal life in this park has not been studied. Some of the most conspicuous mammals are howler monkey (Alouatta palliata), white-nosed capuchin (Cebus capucinus), common raccoon (Procyon lotor) and white-nosed coati. Easily identifiable birds include the white hawk (Leucopternis albicollis), the chestnut-mandibled toucan (Ramphastos swainsonii) and the short-billed pigeon (Columba nigrirostris), which is found in large numbers. Out to sea, off the national park, there are patches of coral reef.
This park is located in the eastern part of Dulce Gulf not far from Golfito. A few dirt tracks allow visitors to access the properties being purchased in order to see the forest and its biological diversity. In Golfito, there are hotels, restaurants and markets.
