The Negritos Islands Biological Reserve, located in the Gulf of Nicoya, was included in the national park system on December 27th 1982, to preserve plentiful populations of marine birds, its flora and fauna, to protect seabird nesting colonies and to spare them from other developments. The climate here is hot and sunny most days of the year. The island is part of the Guayabo, Negritos and Pajaros Biological Reserve. The small amount of rain falls between May and November.
The Negritos Islands are neighbors of Tortuga Island in the Gulf of Nicoya, and comprise two islands separated by a narrow channel. Consisting of basalts and breaches of the Nicoya complex and are covered in semideciduous forest. The predominant trees are Frangipani (Plumeria rubra), Spiny cedar (Bombacopsis quintanum), lacewood (Calycophyllum candidissimum) and gumbo-limbo (Bursera simaruba). In some parts, near the rocks, there are homogeneous patches of chira (Bromelia pinguin) and palm (Bactris guineensis).
The waters surrounding these islands are very rich in marine fauna; some of the most common fish are the Pacific Red Snapper (Lutjanus), the Spotted Rose Snapper (Lutjanus guttatus) and the Yellow Snapper (Lutjanus argentiventris). Some of the animals that live in this island are raccoons, parrots, doves, hermit crabs (which are very numerous), brown pelicans and oysters, and also the Yellow-naped Parrot (amazona auropalliata) nests here. In addition, there are some populations of dolphin, tuna and mackerel around the island as well.
The Negritos Islands Biological Reserve maintains no facilities or trails for visitors on the island, but in Puntarenas there are hotels, restaurants, markets and it is possible to hire boats, due to every island being accessible by boat from Puntarenas, for closer examination. Also, to visit them, you may need a permit from the Tempisque Conservation Area.
Getting to Los Negritos Island Biological Reserve:
From San Jose take the Pan-American Highway to the Puntarenas exit, passing through San Ramon and Barranca. Probably the easiest way to see the Los Negritos Island is to take one of the daily cruises from Puntarenas to Tortuga Island, since the route taken on these excursions passes by these islands. Now you can also take the new Caldera Highway (route 27), until you get to Punta Morales, passing through the Puntarenas entrance. The Caldera trip takes about 1 hour from San Jose while the other takes about 2 hours.
From Daniel Oduber International Airport (LIR), drive south on the Pan-American Highway to Puntarenas. Probably the easiest way to see the Los Negritos Islands is to take one of the daily cruises from Puntarenas to Tortuga Island, since the route taken on these excursions passes by these islands.
Take a bus from the route San Jose – Puntarenas, which takes about 2 hours and then take a boat, preferably to Tortuga Island, to observe the Los Negritos Island Biological Reserve.
Location: 16.5 km south Puntarenas, in Nicoya Gulf.
