Costa Rica Animals: Discover the Incredible Wildlife of the Rainforest

When you think of Costa Rica, you probably picture lush rainforests, colorful birds, and exotic creatures hidden in the jungle. And you’re absolutely right! Costa Rica is one of the most biodiverse countries on Earth — home to over 500,000 species, representing nearly 5% of all life on the planet.

From sleepy sloths hanging in the treetops to red-eyed tree frogs perched on leaves, Costa Rica’s animals are part of what makes this country so magical. Whether you’re hiking through a national park, relaxing on the beach, or joining a guided wildlife tour, you’ll find that nature here is always close by.

In this guide, we’ll introduce you to the most iconic Costa Rica animals, where to find them, and how to experience the country’s wildlife responsibly.

Monkeys of Costa Rica

You can’t visit Costa Rica without encountering monkeys — they’re some of the most playful and entertaining animals to watch (and so cute!)

There are four species of monkeys in Costa Rica:

• Howler Monkey – Known for their deep, roaring calls that echo through the forest at sunrise. They are black, and very often you see their white testicles.

• White-Faced Capuchin – Smart, curious, and often spotted near beaches and national parks. Be careful with your belongings; they love to rummage through bags looking for food.

• Spider Monkey – Agile acrobats swinging through the treetops in dense rainforests.

• Squirrel Monkey – The smallest and most endangered species, found mainly in Manuel Antonio and Corcovado.

Best places to see them: Manuel Antonio National Park, Monteverde Cloud Forest, Corcovado National Park.

Sloths: Costa Rica’s Favorite Animal

If there’s one creature that embodies the Pura Vida lifestyle, it’s the sloth. With their gentle smiles and slow movements, sloths are a favorite among visitors.

There are two types of sloths in Costa Rica:

• Two-toed Sloth – Nocturnal and harder to spot.

• Three-toed Sloth – Active during the day and easier to photograph.

Best places to see them: La Fortuna, Monteverde, and Cahuita National Park. You can also book a guided wildlife tour for your best chance to spot them up close.

Colorful Frogs and Amphibians

Costa Rica is a paradise for frog lovers! The red-eyed tree frog, with its bright green body and scarlet eyes, has become an unofficial national symbol. You’ll also find blue jeans poison dart frogs, glass frogs, and other unique amphibians throughout the country.

These creatures are most active during the rainy season (May–November), especially on night walks in the rainforest.

Best places to see them: Monteverde, Sarapiquí, and Tortuguero.

Birds: A Paradise for Birdwatchers

Costa Rica is home to over 900 bird species, making it one of the top birdwatching destinations in the world. You don’t need to be an expert to appreciate their beauty — even casual travelers will be amazed by the colors and sounds.

Top birds to watch for:

• Resplendent Quetzal – A stunning green and red bird sacred to ancient Mayans.

• Scarlet Macaw – Bright red and yellow parrots often seen flying in pairs.

• Toucans – Famous for their large, colorful beaks.

Best places to see them: Monteverde Cloud Forest Reserve, Osa Peninsula, Arenal Volcano National Park.

Big Cats and Other Jungle Predators

Spotting a jaguar or puma in Costa Rica is rare, but knowing they roam the forests adds a sense of wild mystery. Costa Rica’s national parks protect these elusive cats along with ocelots, margays, and jaguarundis.

If you’re lucky, you might also encounter coatis, anteaters, and armadillos along the trails.

Best places to see them: Corcovado National Park and Tortuguero National Park (on a guided night or wildlife tour).

Sea Turtles on Costa Rica’s Beaches

Every year, thousands of sea turtles come ashore to nest on Costa Rica’s beaches — one of the most incredible wildlife experiences you can witness.

Different species visit at different times of the year:

• Green and Hawksbill Turtles: Tortuguero (July–October)

• Olive Ridley Turtles: Ostional and Santa Rosa (July–December)

• Leatherback Turtles: Playa Grande and Cahuita (March–July)

Best places to see them: Tortuguero National Park, Ostional Wildlife Refuge, Playa Grande near Tamarindo.

If you go, remember to join an official turtle-watching tour — this helps protect the nesting sites and supports local conservation efforts.

Reptiles and Rainforest Surprises

Costa Rica is full of surprises — you might spot iguanas basking on rocks, basilisk lizards running on water (yes, literally!), and harmless snakes curled up in the trees.

The country also has crocodiles and caimans, especially along rivers like the Tarcoles — where the famous “Crocodile Bridge” attracts brave onlookers.

Best places to see them: Tarcoles River, Palo Verde National Park, Osa Peninsula.
