About Osa Conservation Area

The Osa Conservation Area protects one of the most biologically diverse regions in the world on Costa Rica’s southern Pacific coast, offering unparalleled wildlife viewing and rich tropical ecosystems.

Wilderness Landscape & Natural Heritage

The Osa Conservation Area (Área de Conservación Osa) encompasses a vast network of protected lands and marine areas on the Osa Peninsula and its surroundings, located in Puntarenas province, Costa Rica. It is internationally renowned for its exceptional biodiversity, earning the designation as part of the UNESCO La Amistad Biosphere Reserve. The conservation area integrates several national parks and wildlife refuges, including Corcovado National Park, Piedras Blancas National Park, and Ballena Marine National Park, safeguarding critical tropical rainforest, mangroves, wetlands, and coastal marine habitats. The terrain is characterized by rugged mountains, pristine beaches, dense rainforests, and extensive river systems. Ecologically, it supports a remarkable range of flora and fauna, including endangered species like jaguars, tapirs, scarlet macaws, and the giant river otter. Its protection efforts help maintain one of the last large wilderness areas along the Pacific coast of Central America. Outdoor recreation here centers on jungle trekking, wildlife watching, birding, snorkeling, and surfing. Corcovado National Park provides some of the most pristine rainforest trails in Costa Rica. Visitors are drawn by the opportunity to witness rare wildlife in their natural habitat, explore remote waterfalls, and enjoy unspoiled beaches. The Osa Conservation Area’s mix of terrestrial and marine ecosystems makes it a premier destination for ecotourism and conservation research. Strict management protocols ensure minimal human impact while offering immersive nature experiences. Its remote location and limited infrastructure contribute to its allure, making it a must-visit for dedicated nature lovers and adventurers seeking authentic tropical wilderness encounters.
