World biodiversity

Costa Rica covers just 0.03% of Earth's surface but contains nearly 6% of the world's biodiversity. With over 500,000 species crammed into an area smaller than West Virginia, wildlife encounters are not just possible — they are guaranteed.

After 15 years of guiding wildlife tours, we have learned exactly where and when to find Costa Rica's most sought-after animals. This guide shares our insider knowledge so you can maximize your wildlife sightings.

Animals You Will See in Costa Rica

Three-Toed Sloth in Costa Rica

Three-Toed Sloth

Perezoso de tres dedos

Costa Rica's most beloved animal. These gentle creatures spend 15-20 hours a day sleeping and move so slowly that algae grows on their fur, giving them a greenish camouflage.

Where to See Them

Manuel Antonio, Caribbean coast, Arenal area

Best Time

Early morning or late afternoon when they feed

Pro Tip

Look for round shapes in cecropia trees — their favorite food source. Guides can spot them instantly.

White-Faced Capuchin Monkey in Costa Rica

White-Faced Capuchin Monkey

Mono carablanca

The most commonly seen monkey in Costa Rica. Highly intelligent and curious, they often approach tourists. Watch your belongings — they are known to grab bags looking for food.

Where to See Them

Manuel Antonio, Guanacaste dry forests, Arenal

Best Time

Active throughout the day, especially mornings

Pro Tip

Never feed them — it makes them aggressive and dependent on humans. Keep food in closed bags.

Howler Monkey in Costa Rica

Howler Monkey

Mono congo

You will hear them before you see them. Their howl travels 3 miles through the forest and is one of the loudest sounds made by any land animal. Despite the fearsome sound, they are vegetarians eating leaves and fruit.

Where to See Them

Throughout Costa Rica, especially Guanacaste and Osa Peninsula

Best Time

Dawn and dusk when they vocalize most

Pro Tip

Do not stand directly under them — they sometimes drop branches on perceived threats.

Resplendent Quetzal in Costa Rica

Resplendent Quetzal

Quetzal resplandeciente

Considered one of the world's most beautiful birds. Males have iridescent green plumage and tail feathers up to 3 feet long. The Aztecs and Mayans considered them sacred — their feathers were worth more than gold.

Where to See Them

Monteverde Cloud Forest, San Gerardo de Dota, Los Quetzales National Park

Best Time

March to June (breeding season), early morning

Pro Tip

Hire a local guide — they know the nesting trees and can spot quetzals that visitors walk right past.

Keel-Billed Toucan in Costa Rica

Keel-Billed Toucan

Tucan pico iris

The iconic rainbow-billed toucan is Costa Rica's most recognizable bird. Despite its large bill, it is surprisingly light — made of keratin with hollow chambers inside. They use it to reach fruit on thin branches.

Where to See Them

Arenal, Caribbean lowlands, Sarapiqui region

Best Time

Morning and late afternoon near fruiting trees

Pro Tip

Listen for their croaking call — it sounds like a frog, not what you would expect from such a colorful bird.

American Crocodile in Costa Rica

American Crocodile

Cocodrilo americano

American crocodiles can grow up to 16 feet long. The Tarcoles River bridge on the road to Manuel Antonio is famous for guaranteed sightings — some of the largest individuals in Costa Rica live below.

Where to See Them

Tarcoles River, Tempisque River, Tortuguero canals, Damas Island

Best Time

Midday when they bask in the sun on riverbanks

Pro Tip

Never swim in river mouths or estuaries — crocodiles are always present even if you cannot see them.

Green Sea Turtle in Costa Rica

Green Sea Turtle

Tortuga verde

Tortuguero on the Caribbean coast is one of the world's most important nesting sites — the name literally means 'place of turtles.' Females return to the exact beach where they were born to lay their eggs.

Where to See Them

Tortuguero (Caribbean), Ostional, Playa Grande, Las Baulas (Pacific)

Best Time

July to October (Caribbean), September to March (Pacific)

Pro Tip

Night nesting tours must be with certified guides. Flashlights and flash photography are prohibited.

Scarlet Macaw in Costa Rica

Scarlet Macaw

Lapa roja

These stunning red, yellow, and blue parrots mate for life and can live up to 75 years. Once endangered in Costa Rica due to habitat loss and poaching, conservation efforts have helped populations recover significantly.

Where to See Them

Carara National Park, Osa Peninsula, Central Pacific beaches

Best Time

Early morning when they fly to feeding areas, evening return flights

Pro Tip

Look for almond trees along beaches — macaws love the nuts and gather in large flocks to feed.

Wildlife Watching Tips From Our Guides

Always Hire a Local Guide

This is our number one tip. A trained naturalist guide will help you see 10-20 times more animals than going alone. They know the trees, the calls, the behavior patterns. Worth every dollar.

Start at Dawn

Most animals are active between 5:30-8:00 AM. If your tour starts at 9 AM, you have already missed the best wildlife activity. We start most tours at sunrise.

Bring Good Binoculars

Essential for birdwatching and spotting sloths in the canopy. 8x42 binoculars offer good magnification without being too heavy. Your guide will have a scope for distant birds.

Move Slowly and Quietly

Quick movements and loud voices scare animals away. Walk slowly, speak in whispers, and wear earth-tone colors. Patience is rewarded.

Never Feed Wildlife

Human food harms animals and makes them aggressive toward tourists. Monkeys that are fed become bold enough to steal bags and bite people. It is also illegal in national parks.

Respect Distance

Use zoom lenses for photos instead of approaching animals. Getting too close causes stress and can be dangerous. A 200-400mm lens is ideal for wildlife photography.
