Why Is Corcovado National Park So Rich in Wildlife?
Corcovado National Park protects more than 42,000 hectares of tropical rainforest, rivers, lagoons, beaches and coastal habitats.
These diverse ecosystems support hundreds of animal species and create one of the richest concentrations of wildlife in the Americas.
Unlike many protected areas, Corcovado still contains extensive areas of primary rainforest, where ecosystems have remained largely unchanged for thousands of years.
This combination of habitats allows many different species to coexist within a relatively small area, making every hike an opportunity to observe something new.
Although wildlife sightings are never guaranteed, Corcovado offers some of the best opportunities in Costa Rica to observe animals living freely in their natural environment.
