Introduction: The Last Frontier of Biodiversity
The Osa Peninsula, described by National Geographic as the most biologically intense place on Earth, remains a primary destination for travelers seeking genuine immersion in tropical ecosystems. Unlike the more developed tourist hubs of Guanacaste, the Osa Peninsula requires a deliberate, conservation-minded approach to travel.
Why Sustainability Matters in Osa
According to the Sistema Nacional de Áreas de Conservación (SINAC), the peninsula houses 2.5% of the world's biodiversity. Because the region is dominated by Corcovado National Park, the margin for environmental error is slim. Travelers are encouraged to prioritize low-impact lodging and certified local guides.
Essential Travel Logistics
Getting There
Travelers typically arrive via Sansa Airlines flights from San José (SJO) to Puerto Jiménez or Drake Bay. While road travel is possible via the Interamerican Highway, it is a 7-9 hour drive that requires a 4x4 vehicle during the rainy season.

Feeding animals can lead to dependency and behavioral changes that endanger the species.
