Corcovado is one of the rainiest regions in the country with records of up to 5,500 mm. of rainfall on the highest peaks.
There are 500 species of trees in the entire park, which is a fourth of all the tree species that exist in Costa Rica.

In this park you will find the biggest tree in all the country, an enormous silk cotton tree that reaches a height of over 70 meters.

The wildlife in Corcovado is as abundant and varied as its plant life. The park protects several species that are in danger of extinction both in Costa Rica and in the greater part of the American tropics, such as large felines and reptiles.

The park is also the home of several bird species that are either endemic or of limited range. In general it is known that there are 140 species of mammals, 367 of birds, 117 of amphibians and reptiles and 40 of freshwater fish, and it is estimated that approximately 6,000 insects live in the park, including the 123 butterflies discovered so far.

The herpetological fauna is not far behind in terms of variety and number. Studies carried out in the park have recorded 20 species of saurians, 33 of ophidians or snakes, 48 of toads and frogs, and 7 of turtles, besides salamanders, crocodiles and caimans.
Three species of amphibians that are especially noteworthy are the glass frogs, which are so transparent that their internal organs can be seen through their skin, and the poison dart frog (endemic specie of Costa Rica)

One of the biggest problems that this park faces is the entrance of illegal miners who sneak into southern and southeastern sectors where they look for gold, this prized metal is found in rivers and their banks.
