Fodor's Expert Review Braulio Carrillo National Park

In a country where deforestation is still rife, hiking through dense, primary tropical cloud forest is an experience to be treasured. The park owes its foundation to the public outcry provoked by the construction of the highway of the same name through this region in the late 1970s—the government bowed to pressure from environmentalists and, somewhat ironically, Braulio Carrillo is the national park that is most accessible from the capital, thanks to the highway. Covering 443 square km (171 square miles), the extremely diverse terrain ranges from 180 feet to about 9,500 feet above sea level and extends from the central volcanic range down the Caribbean slope to La Selva research station near Puerto Viejo de Sarapiquí. The park protects a series of ecosystems ranging from the cloud forests on the upper slopes to the tropical wet forest of the Magsasay sector; it’s home to 6,000 tree species, 500 bird species, and 135 mammal species.

Despite the park's immense size and proximity to the capital, visitor facilities are extremely limited. Stories abound of visitors becoming lost trying to do Braulio Carrillo on their own. Few venture deep into the park beyond the highway that cuts through it.
