Corcovado National Park Published Guides: Regional Geography and Landscape Analysis

Costa Rica's largest national park protecting one of the world's most biodiverse tropical rainforests

Corcovado National Park

Corcovado National Park represents one of Central America's most significant protected areas, encompassing the majority of the Osa Peninsula in southwestern Costa Rica. This vast tropical landscape serves as the last major stronghold of lowland rainforest along the Pacific coast of the Americas, a region that has suffered extensive deforestation over the past century. The park's creation in 1975 marked a pivotal moment in Costa Rican conservation history, coming at a time when industrial logging operations threatened to eliminate what remained of the peninsula's virgin forest. The geographical setting of Corcovado is defined by the rugged terrain of the Osa Peninsula, which extends into the Pacific Ocean creating a unique convergence of marine and terrestrial ecosystems. The park encompasses coastal beaches, mangrove swamps, lowland rainforest, and ascending into cloud forest at higher elevations. This topographic diversity supports an remarkable array of habitats, each harboring distinct communities of plants and animals. The montane forest zone dominates more than half the park's area, while the lower elevations feature specialized ecosystems including jolillo palm swamps and freshwater herbaceous wetlands. What distinguishes Corcovado from other protected areas is its role as a biological bridge between North and South America. The peninsula's position along the Mesoamerican isthmus has created a natural funnel for species migration, resulting in a blend of temperate and tropical biodiversity found nowhere else. This geographical advantage, combined with the variety of microhabitats created by the park's elevation range and water systems, has produced an ecosystem of exceptional richness. The park's rivers and coastal waters further extend this biodiversity into the marine realm, supporting populations of crocodiles, bull sharks, dolphins, and seasonal whale visitors.
