Corcovado National Park covers much of the remote Osa Peninsula in southern Costa Rica. National Geographic once called it one of the most biologically intense places on Earth. In fact, it protects about 2.5% of the planet’s biodiversity. So, it is a dream for wildlife lovers.
This guide covers the wildlife, trails, beaches, rules and practical tips.

Wildlife in Corcovado
- Mammals: Baird’s tapirs, jaguars, pumas and ocelots live here. Also, all four Costa Rican monkey species are present.
- Birds: Scarlet macaws, toucans and about 400 other species.
- Marine life: Dolphins, whales and sea turtles swim along the coast.



Hiking Trails in Corcovado
Sirena Ranger Station
Deep inside the park, Sirena is the best place to see wildlife. Usually, visitors stay overnight in its basic lodge. Then, early morning walks reveal tapirs and monkeys.
La Leona to Sirena
This trail follows the beach for about 16 km. However, it is hot and long, with river crossings. So, plan around the tides, as your guide will advise.
Park Rules
Since 2014, all visitors must enter with a certified guide. Also, entry permits must be booked in advance. As a result, the park stays wild and well protected.
Beaches and Caño Island
Furthermore, Playa Madrigal and other beaches are wild and empty. Meanwhile, Caño Island lies offshore, a protected reserve for snorkelling and diving. There, you may see turtles, rays and reef sharks.


Best Time to Visit Corcovado
The dry season, from December to April, is best for hiking. In contrast, heavy rains make trails difficult from September to November. Also, some areas may close during the wettest months.
Practical Tips
- Book a tour: Guides arrange permits, transport and food.
- Pack light: Bring quick-dry clothes, insect repellent and a headlamp.
- Carry cash: There are few ATMs on the peninsula.
Getting There
Most visitors start from Drake Bay or Puerto Jiménez. Usually, boats or long hikes reach the ranger stations. Also, small planes fly from San José. For permits, see the official SINAC website.
