Home to one of the largest rainforests in Central America (widely protected by Corcovado National Park), the Osa Peninsula is the wildlife and hiking jewel of Costa Rica. Dubbed "the most biologically dense place on Earth," you can see much of the country's famed wildlife by hiking through the jungle and watching whales and dolphins in Drake Bay. Then, take your adventures to the next level by surfing, snorkeling, and scuba diving at Cape Matapalo and Isla del Caño Biological Reserve.

Getting Oriented

The lush greenery of the Osa Peninsula.

Costa Rica has two peninsulas on its Pacific side, both appearing in the same unique shape. The Osa Peninsula is the smaller, southern one near the Panama border. Known as "the most biologically dense place on Earth," Osa is nearly covered by Corcovado National Park, which protects one of the largest rainforests in Central America. Besides the numerous exotic bird species in the park, you can also see sloths, sea turtles, and even big cats like the puma, ocelot, and endangered jaguar.

But as a peninsula, there's a lot more to Osa than just its jungles and forests. You can watch whales and dolphins in Drake Bay and explore the Isla Caño Biological Reserve reefs. Here you'll find the country's largest concentration of coral-building organisms, which provide homes and feeding grounds to an abundance of marine life. With all this nature surrounding you, consider staying in one of the eco-lodges on the Osa Peninsula to make the experience even more special!


One of the best ways to experience the Osa Peninsula is by hiking through the rainforest. Immerse yourself in the area's dense forests, where you'll find rivers, creeks, waterfalls, and, of course, wildlife.

Your destination is a powerful waterfall that creates a pool perfect for swimming. It's especially refreshing to take a dip after a hike! Read More

How to Craft the Perfect Osa Peninsula Itinerary

The Osa Peninsula has some of the most serene scenes in Costa Rica.

Many travelers opt to visit the Osa Peninsula and nothing more when in Costa Rica! The region is truly special and offers a range of activities centered around the country's beautiful rainforests and wildlife. If you'd like to stick to the peninsula, it's best to give yourself at least five days, although you could easily fill a week-long itinerary with just Osa alone!

If you're wondering how many days to spend in Costa Rica if you'd like to see more than the Osa Peninsula, that depends on how far you want to travel. Remember that Osa is in the far south of the country, so if you're going to combine it with other regions in Costa Rica, plan for at least one week. However, two weeks in Costa Rica makes traversing the country much easier.
