Osa / Corcovado
The most biodiverse place on Earth
About Osa & Corcovado
The Osa Peninsula is home to Corcovado National Park — described by National Geographic as 'the most biologically intense place on Earth.' The park protects over 400,000 hectares of primary rainforest, containing an estimated 2.5% of the world's biodiversity in an area smaller than Rhode Island.
Corcovado is one of the last places in Central America where jaguars, pumas, tapirs, and giant anteaters still roam freely. Four species of sea turtle nest on its beaches. The park is remote and requires planning — access is by boat or small plane, and overnight stays require advance permits. The experience is unlike anything else in Costa Rica.
Highlights
- Corcovado National Park
- Jaguar, puma & tapir sightings
- Scarlet macaw colonies
- Four species of sea turtle
- Whale watching (Drake Bay)
- Snorkeling at Cano Island Biological Reserve
- Primary rainforest hiking
Getting there & around
The Osa Peninsula is reached by small plane from San Jose to Puerto Jimenez or Drake Bay (45 minutes), or by road to Puerto Jimenez (7 hours) followed by boat to park stations. Access to Corcovado requires a certified guide and advance permits from SINAC.
View transport optionsHow long to stay
3–5 nights minimum for Osa/Corcovado. The park requires advance permits and is best explored over 2–3 days with an overnight stay inside or near the park. Rushing Corcovado is a mistake — the wildlife rewards patience.
Best season
The dry season (December–April) makes trails more accessible and wildlife more concentrated around water sources. The wet season (May–November) brings extraordinary lushness and fewer visitors, but some trails may be impassable. The park is open year-round with advance permits.
Combine with
Osa/Corcovado pairs naturally with Drake Bay (1 hr by boat) — many visitors arrive by boat from Drake and exit via Puerto Jimenez. Uvita is 2 hours north. A South Pacific circuit ending at Corcovado is one of Costa Rica's most rewarding itineraries.
Travel tips
- Corcovado requires a certified guide — independent access is not permitted.
- Book permits and guides well in advance — the park limits daily visitor numbers.
- The wet season (May–November) brings heavy rain but also the most wildlife activity.
- Cano Island Biological Reserve offers world-class snorkeling and diving — book a boat tour from Drake Bay or Puerto Jimenez.
- Bring waterproof gear, insect repellent, and sturdy hiking boots — the terrain is demanding.
Tips by traveler type
Naturalists
A certified naturalist guide is mandatory for entering Corcovado. The quality of your guide determines the quality of your experience — book through a reputable operator.
Wildlife photographers
The San Pedrillo and La Leona ranger stations offer the best jaguar and tapir sighting opportunities. Overnight stays inside the park dramatically increase your chances.
Eco-travelers
Corcovado requires advance permits from SINAC. Book at least 2–3 months ahead for peak season. Overnight stays inside the park are limited — they sell out fast.
