In 5,000 hectares, El Imposible National Park is home to over 400 species of trees. The Ceiba and Ojuste are a few of the largest and as the park guides will point out many of the plants and trees have medicinal uses.
It is estimated there is between 5,000 and 6,000 species of butterflies. Also armadillos, wild boars, ocelots, white tailed deers, ant eaters and an occasional puma can be spotted in the park.
El Imposible is habitat to a reported 285 species of birds including the magnificent Rey Zope (King Vulture).
The terrain of the park is very steep but has a substantial network of trails that should satisfy any avid hiker.
