Irazu, or “the powder keg of nature”, as it was called, is an irregular active volcano with a stratospheric sub conical shape. It towers 3432 meters above sea level and covers 500 square kilometers.
There are four craters on the summit of Irazu, the main crater anotherone, named Diego de la Haya, and two small craters on the northwest and southeast areas of the park.
The vegetation has undergone considerable changes due to the eruptions. Today it is possible to see places with sparse flora at the edge of the crater. Elsewhere, its possible to find patches of secondary forest and primary forest.
Wildlife in Irazu is very uncommon. Some of the mammals were seen near the summit, the eastern cottontail (species of rabbits), porcupines, coyotes, armadillos, tiger cats and weasels. As far as birds are concerned, mountain robins, woodpeckers and hummingbirds are a common sight, in contrast to the eastern meadowlark and a long tail ptinlogonys which have small populations been recorded.
