Barbilla National Park is located on the eastern slopes of the Cordillera de Talamanca in Costa Rica, within the SINAC Caribbean La Amistad Conservation Area. The park protects 11,938 hectares (29,500 acres) of humid lowland rainforest along the Caribbean slopes of the Talamancan mountain range.
The park also protects the Dantas River Watershed, which is an important source of water for the people and animals of the region. Barbilla National Park is a part of the Talamanca-La Amistad Biosphere Reserve and is located next to the Chirripó Indigenous Reserve. The park is home to the second largest indigenous group in Costa Rica, the Cabécar.
It is one of the country's least-visited parks, which has allowed the park to remain ecologically rich and diverse. Rare and even endangered species live within the park, including jaguars, ocelots, pumas, and tapirs.
An annual rainfall of 140-180 inches keeps the park wet and verdant, allowing a great amount of biological diversity to flourish. Several of these species are endangered, including the puma, jaguar, ocelot, tapir, and several birds of prey.
The Barbilla Biological Station, which is run by the National Institute of Biodiversity, is located within the park.
