32,512 hectare national park was founded in 1991 in
the Province of Guanacaste, some 36 kilometers North
of the city of Liberia. The park centers around the
Orosi and Cacao Volcanos. It should be noted that
the headwaters of the great Tempisque River lies within
the park between Cacao Volcano and Orosillito Mountain.
Since the park covers both the wet Caribbean side
as well as the drier Pacific side, it contains a wide
diversity of climatic zones. The primary forest on
the tops of Cacao and Orosi Volcanos contains a wide
variety of epiphytes, especially bromeliads and orchids.
Because of the wide climatic variations, there are
also wide variations in the numbers of species of
plants and animals. The are over 300 types of birds
and an estimated over 5,000 species of moths and butterflies.
