Costa Rica
Osa Peninsula & South Pacific

Corcovado — Earth's most biologically intense national park — and the best humpback whale watching in the Americas.
The Osa Peninsula is for travellers who have already seen the rest of Costa Rica and want to go further. Corcovado National Park is famously described as "the most biologically intense place on Earth" by National Geographic: Baird's tapirs, harpy eagles, white-lipped peccaries, all four Costa Rican monkey species, and the densest jaguar population in Central America survive here because the park is genuinely remote and genuinely hard to reach. The Pacific south coast — Uvita, Dominical, and the Marino Ballena National Park — is where humpback whales pass twice a year (July–October from Antarctica, December–March from California), offering some of the most accessible whale watching on the planet.

What you gain
- ↑Corcovado day hikes (guided, required) offer the highest probability of seeing large mammals — Baird's tapir, white-lipped peccary, squirrel monkey — that have disappeared from every other accessible area of Costa Rica
- ↑Marino Ballena National Park (Uvita) and Drake Bay offer humpback whale watching from July–October and December–March — two annual windows and some of the world's highest sighting success rates
- ↑The Osa is genuinely remote: the lack of tourist infrastructure that makes it hard to reach also means that when you arrive, the wildlife and landscape feel undisturbed in a way that no other Costa Rica region can match
What you sacrifice
- ↓Getting to Corcovado requires either a flight to Puerto Jiménez (expensive) or a very long drive on dirt roads; the park itself requires a licensed guide (no solo entry) and advance reservation through the park system
- ↓The Osa is not a good fit for short trips: the journey time, combined with guide-required hikes and limited accommodation options, means you need at least 3–4 dedicated nights to justify the logistics
