The national park was established in 1955 to protect 2309 hectares in a roughly circular shape around the volcano. The Principal Crater is 1050 meters in diameter and 300 meters deep. The Diego de a Haya Crater is 690 meters in diameter and 100 meters deep. It contains a small lime-green lake (some days it is red).
The name of this subconical volcano derives from an indigenous word meaning thunder and earthquake mountain. Documented since 1563, Irazus activity means that access to some of its craters may be restricted, but the principal lake (sometimes it is lime-green and other days it is red), an almost perfect circle with steeply inclined walls and the Diego de la Haya Crater are usually accessible. If the trail is open to the western side, you may have rare views of both oceans and, with a telescope, of Lake Nicaragua.
vegetation is premontane and montane wet forest, partly lichen-draped,
interspersed with open grass and scrublands. The lower you get the, lusher
vegetation. Birds are scarce due to deforestation and volcanic activity,
but include clay-colored robins, mountain robins, owls, hummingbirds and
volcano juncos. Rabbits, grey foxes, armadillos, porcupines, coyotes and
tiger cats can also been spotted.
