Costa Rica's largest national park protecting one of the world's most biodiverse tropical rainforests
Corcovado National Park
Corcovado National Park occupies the bulk of the Osa Peninsula in southwestern Costa Rica, standing as the nation's largest protected area at 424 square kilometers. Established in 1975, the park encompasses one of the few remaining substantial tracts of lowland tropical forest in the world and harbors the largest primary rainforest on the entire American Pacific coastline. The park sits within the Osa Conservation Area and is managed by Costa Rica's National System of Conservation Areas (SINAC), representing a cornerstone of Central American conservation efforts.
The ecological significance of Corcovado is extraordinary, with the park containing approximately three percent of the world's biodiversity despite covering just 41,800 hectares. This concentration of life is partly due to the peninsula's position as a natural corridor linking the continents of North and South America, allowing species from both hemispheres to converge. The park features remarkable diversity across its thirteen distinct vegetation zones, ranging from montane forest covering more than half the park area to cloud forests, palm swamps, freshwater wetlands, and mangrove ecosystems along the coast.
Beyond its biological wealth, Corcovado represents a complex intersection of conservation challenges and community relationships. The park's creation came in response to escalating deforestation pressures from logging, mining, and agricultural expansion, yet the transition to protected status created tensions with local communities whose livelihoods depended on these lands. Today, the park faces ongoing threats from illegal gold mining and hunting, while also managing the impacts of growing ecotourism. This dynamic landscape of protection and pressure makes Corcovado not only a vital ecological sanctuary but also a case study in the challenges of tropical forest conservation.
