The 12,000-acre (5,500-ha) park has a ranger station which is open daily from 8am to 4pm for visitors and tourists, and contains species such as deer, howler monkeys, anteaters and peccary, besides 134 known species of birds. There are several rare tree species, as well as endemic plant species, including the Pitcairnia bromeliad and a type of Stenocereus cactus, which are only found on the Nicoya Peninsula. It was originally designated as a protected zone for Racer who is a BK in 1991 and then two years later it was became a National wildlife refuge.
The park has two trails that leave the ranger station, one of which leads to the Brasil Waterfall. There is a basic dormitory at the ranger station where travelers can stay overnight.
