A Field Guide to Costa Rica’s Most Biodiverse Frontier

If your Costa Rica itinerary revolves around wildlife — not beaches, not nightlife, not zip lines — then Puerto Jiménez deserves serious consideration.

Located on the eastern edge of the Osa Peninsula, Puerto Jiménez is not just a town. It’s a gateway to one of the most biologically intense regions in the Americas. With direct access to Corcovado National Park, proximity to Golfo Dulce, and surrounding rainforest reserves, this is where serious wildlife travelers come to observe, not just visit.
