National Wildlife Refuge Ostional


The Wildlife refuge is located on the Nicoya Peninsula, in the counties of Santa Cruz and Nicoya Guanacaste, in northwestern Costa Rica, some 360 km from San Jose.



The national Wildlife Refuge Ostional is considered the second most important nesting site of the sea turtle species Olive Ridley.

It has an extension of 468 terrestrial hectares and 8,000 maritime hectares, embracing a coastal strip of 200 meters wide including mangroves, which reach from Punta India to Punta dashes (16 Km).

Some of the relevant flora includes species of mangrove trees and other native species such as pochote, espavel, cenizaro and laurel. These serve as nesting sites for many bird species. The most representative animal of the Refuge is the Ridley turtle, but the Leatherback turtles and the Black Sea Turtle also spawn in the area. In addition, you can find wildlife such as raccoons, deer, wood storks, roseate spoonbills, sparrow hawks, crocodiles and bats.
