Five Unmissable Wildlife Encounters in Costa Rica

Costa Rica is one of the best places in the world for close encounters with wildlife. Thanks to its rich ecosystems, strong conservation policies and network of well-managed parks and reserves, the country offers exceptional opportunities to observe animals in their natural habitats. Whether you’re trekking through rainforest, cruising along canals or relaxing on the coast, the country’s biodiversity is always on display.

Here are five of the most memorable wildlife encounters you can experience in Costa Rica.

1. Watching Sea Turtles Nest at Tortuguero

Each year, thousands of green sea turtles return to the black-sand beaches of Tortuguero National Park to lay their eggs – one of nature’s most remarkable rituals. Nesting season runs from July to October, with night-time guided beach walks offering the chance to see females digging nests, laying eggs and returning to the sea.

Later in the season, you might even witness hatchlings making their way to the water – a deeply moving moment that’s difficult to forget.

2. Spotting Sloths in the Rainforest

Few animals capture the imagination quite like the sloth. Costa Rica is home to both the two-toed and three-toed varieties, and spotting one in the treetops is a highlight of many trips.

Sloths can be seen in numerous locations, including the rainforests of Arenal, Monteverde and Manuel Antonio. Though often slow-moving and well-camouflaged, expert guides have an uncanny ability to spot them, especially during early morning walks.

3. Listening to a Howler Monkey Dawn Chorus

The guttural roar of the howler monkey is one of Costa Rica’s most distinctive sounds – a low, echoing call that rolls through the forest at dawn. Despite their fearsome vocalisations, howlers are relatively gentle primates and a joy to watch as they feed and groom high in the canopy.

You’ll likely encounter them in protected areas across the country, from Corcovado to the Caribbean coast. Their unmistakable presence adds a soundtrack to your mornings in the wild.

4. Seeing the Resplendent Quetzal in Monteverde

The resplendent quetzal is one of the most iconic birds in the Americas, and Costa Rica is one of the few places where you can see it reliably. With iridescent green plumage and a scarlet breast, the male’s long tail feathers and gentle demeanour make for an unforgettable sight.

Monteverde Cloud Forest Reserve is one of the best places to try your luck. Visit between March and May, when the birds are nesting and often easier to find.

5. Exploring the Remote Wilds of Corcovado

For those seeking a more adventurous encounter, a visit to Corcovado National Park is hard to beat. Situated on the remote Osa Peninsula, Corcovado is considered one of the most biologically intense places on Earth.

Here, you may spot all four of Costa Rica’s monkey species in a single day, alongside tapirs, anteaters, scarlet macaws and maybe even a jaguar or puma. Guided hikes through primary rainforest offer thrilling opportunities to see wildlife that is rarely found elsewhere.

Bonus: Unexpected Encounters in Lodge Gardens

One of Costa Rica’s joys is how often the wildlife comes to you. At many eco-lodges, you can see toucans, hummingbirds, agoutis and coatis right from your balcony. Night walks reveal frogs, owls and insects, while fruiting trees attract all manner of colourful birds.

Whether deep in a national park or sipping coffee outside your cabin, the country’s biodiversity is always within view.
