Guanacaste national park was created in 1989 to protect the volcano slope evergreen forest and the Orosi and Cacao volcanoes, in the cloud forest.  This project was founded following the concept of securing a migrational route for those animals that move into the highlands during the dry season. The park contains several interesting trails and four research stations, of which at least one will remain open for tourists, researchers and photographers.

This national park is located on the east side of the InterAmerican Highway, across from Santa Rosa national park.  positioned at the foot of the Orosi volcano lies Maritza biological station. Here you can find hills that are relicts of Plio-Cuaternary volcanoes an plains that have been formed by the accumulation of ash, pyroclasts and ignimbrites.
