INBIO (Institute of Biodiversity) Park: Its settings and installations are a compendium of Costa Rica's geography, because its trails show "explorers" the flora characteristic of the forest from the Central Valley, the misty tropical forest, and the dry tropical forest.
The Park is an educational area that houses 51 bird species, 583 native plants, as well as an interesting variety of mammals and reptiles. It has stations permanently hosting frogs, tarantulas, bees, ants, bromeliads and orchids, along with a butterfly garden and a lagoon with aquatic flora.
It is located in Santa Rosa, Canton of Santo Domingo, in Heredia. It can be visited Mondays through Sundays from 7:30 hours to 16:00 hours.

Forest of the River La Hoja: Its trails wind flanked by numerous cypresses along green pastures, exhibiting the shades and peculiarities of the forests that pack Costa Rica's Central Valley.
River La Hoja is a pleasant place inviting to relaxation. It is a very popular destination to go on excursions full of adventure and amusement, because this natural area located in Las Chorreras Estate, in Los Angeles, Canton of San Rafael, Heredia, has a campsite, a typical restaurant, a swimming pool and soccer fields; a recreational infrastructure that serves as a complement to the natural beauty of the forest.

La Selva Biological Station: It is a research enclave studying the misty tropical forest, an authentic 2443-hectare paradise that borders and surrounds the Sarapiquí and Puerto Viejo Rivers, a geographical area that is part of the fabulous biological corridor of Braulio Carrillo National Park.
There are more than 1900 plant species and 420 birds in this spectacular kingdom of nature, just to cite two indicators of its prodigal biodiversity. One can find a great variety of monkeys, sloth, peccaries, coatis, caimans, turtles, lizards, frogs and serpents, amongst this life zone.
La Selva Biological Reserve offers guided tours to its visitors. It also has an ample mess. It is located an hour and a half away from San José.

Sarapiquí River: This powerful torrent that wets the forests generating life, rises on the millenarian crater of the Poás Volcano, on the northern side of the Central Cordillera. It has an extension of 85 kilometres approximately and feeds from the waters of several tributaries, such as the Sucio and the Cuarto de Toro.
With a little luck and acute eyes, travellers can watch parrots, jacamars and hummingbirds, amongst other species, on the banks of the Sarapiquí River. Likewise, its imposing course is perfect for the practice of Kayaking and rafting.
But beyond its biodiversity and adventure possibilities, the Sarapiquí is a Natural Historic Monument for it was the main route used by Costa Ricans on their war against the filibusters in 1856.
