Osa Peninsula and Corcovado
"The most biologically intense place on Earth" according to National Geographic: Osa is jungle with a capital J — tapirs on the beach, scarlet macaws in pairs, and zero compromise.
Suggested stay — 3 to 4 nights
At the far southern Pacific, the Osa peninsula remains the last frontier: dirt roads, plank bridges, primary forest down to the ocean. Corcovado park, its heart, is visited only with a certified guide (booking compulsory, by boat from Drake Bay or on foot from Carate): Baird's tapirs nap on the beach, noisy peccary herds pass, four monkey species chatter — and, for the very lucky, a jaguar's fresh track.
Even outside the park, Osa overflows: scarlet macaws squabble in the beach almonds of Puerto Jiménez, dolphins escort the Golfo Dulce boats, humpback whales breed here (July-October and December-March — two hemispheres keep the appointment). It is the trip's far end: 3-4 nights, humidity as uniform, wonder as routine.

Our tips on the ground
- Choose your base: Drake Bay (boat access, end-of-world feel) or Puerto Jiménez (4x4 access, more practical). Both lead to Corcovado.
- Book guide and park quota weeks ahead in the dry season: Sirena's places go fast.
- The Puerto Jiménez–Carate and Drake roads degrade in the green season: fords to wade, and turning back is sometimes the right decision.

Before you go
Readers' questions about Osa Peninsula and Corcovado
Is Corcovado accessible to the unathletic?
Yes in the classic formula: boat + 4-6 km of flat but hot, humid walking around a station. The trek version (a crossing with a night at Sirena) demands real fitness. Either way the guide is compulsory — the best money of the stay, and the park's rule.
Is Osa worth the hours of road from San José?
It is the choice that sorts the trips: 6-7 h of road (or a domestic flight to Drake/Puerto Jiménez) for Central America's richest jungle. On 15 days and more, go; on 10-12, it advantageously replaces two average stops — provided you accept a more rustic rhythm.
