It is in the central [[mountain range]] at 31&nbsp;km to northwest of the city of [[Cartago]], 3,435 meters above sea level. It last erupted in 1963 and 1965. Irazu Volcano National Park offers many types of [[crater]]s, some having small [[lake]]s. The park also includes 2,309 hectares of [[rain forest]]. From the highest point in the park, on a clear day, you can see both, the [[Pacific Ocean]] and the [[Caribbean Sea]] at the same time. The Crater Principal lake has an unusual greenish yellow coloring caused by rainfall dissolving the minerals along the craters walls. It has also been known to change colour to rust-red depending on the minerals present. The inactive, dry Diego de la Haya crater sits just up to the right of the Crater Principal and is filled with volcanic ash. The park is the site of a reforestation project to restore the area which was destroyed by the eruptions. The forest is made up of conifers and other exotic and native species. There is a native forest consisting mainly of [[oak]]s and [[alder]], protecting the watershed of the [[Reventado River]]. The vegetation of the park has been changed by the constant eruptions, but it is very beautiful and diverse. == Other websites == *[http://www.costarica-nationalparks.com/irazuvolcanonationalpark.html Irazu Volcano National Park] {{Webarchive|url=https://web.archive.org/web/20200712132204/http://www.costarica-nationalparks.com/irazuvolcanonationalpark.html |date=2020-07-12 }}
