Best Places to See Costa Rica Wildlife
Which animal would you like to see first? Click on it to skip to the section.
You can see a variety of different whale in Costa Rica on the Pacific side such as pilot whale, blue whale, and sei whales.
However, the prized whale to see is the humpback whale since Costa Rica has the longest humpback whale viewing season in the world. Humpback whales from both the Antarctica and Alaska overlap for a period of time in Costa Rica during their migration.
It’s fairly common to see mom and baby during the beginning of the season as they are rearing and feeding their young. If you’re lucky to see one, they put on some pretty spectacular shows as they’re playing around in the water.
Best time to go whale watching:
- Antarctica humpback whales – July to Nov
California humpback whales – Dec to April
North Atlantic humpback whales – Dec to March
In the months of Oct to Nov, the early birds and late risers overlap.
Best places for whale watching:
- Drake Bay: South Puntarenas, northern region of the Osa Peninsula
- Drake Bay is one of the most isolated places in Costa Rica so you can either take a domestic flight or you can take a boat ride from Sierpe. There are a few tour companies that operate whale and dolphin watching tours.
- During the months of Aug – Nov, you will be sure to see humpback whales at Caño Island and the Corcovado area. The South is definitely the place best to see humpback whales.
- Marino Ballena National Park: In Uvita, 16 km south of Dominical and 180 km SW of San Jose
- There’s a reason why this is called the Whale National Park, this is one of the best places to see humpback whales! This park also has the largest coral reef on the Pacific side of C. America so the marine life here is astounding.
There are a few more places along the Central and North Pacific to go whale watching like Manuel Antonio. We saw humpback whales in the Gulf of Papagayo in the North but it is not quite as common as the South Pacific. In Nicoya, the two best beaches are Tambor and Pochote.
It is pretty common to see dolphins in Costa Rica, especially on the Pacific side. You can see all different species of dolphin from spotted to bottlenose and they are very playful. Sometimes you’ll see them swimming alongside the boat or next to you while kayaking!
Best time to see them: Year round. Many species such as bottle nose and spotted calls Costa Rica all year so you have a good chance to see them.
If you want to see the spinner or common dolphin, they pass by Costa Rica from Dec – March and are not seen as much the rest of the year.
Best place to go dolphin watching: Same places as the whales except you have equal opportunity along the whole Pacific coast. They are especially common to see in the Golfo Dolce by Puerto Jimeenz in the Osa Peninsula. On the Caribbean side, you have a chance to see bottlenose dolphins near Limon.
Many tours combine whale and dolphin watching since the two are commonly seen in the same waters. Some places are Osa Peninsula, Drake Bay, Flamingo, Manuel Antonio and Puerto Viejo.We have seen several times groups of bottlenose dolphins in the Gulf of Papagayo!
Sea turtles in Costa Rica has been declining at an alarming rate the past few years, especially the hawkbill who only have about 8,000 nesting females left in the wild.
In Costa Rica, the turtles are highly protected here and hunting them for food or any other reason is not allowed. The governments allows citizens to collect eggs for special circumstances. Costa Rica has designated certain sites for a turtle refuge and exist solely to help sea turtles.
Best time to see sea turtles: Some turtles are present all year long. You can see sea turtles on both the Caribbean and Pacific.
- Olive Ridley, Hawksbill, Leatherback sea turtle and Pacific Green sea turtle – all year long
- Leatherback sea turtles – Feb to July
- Atlantic green sea turtles – June to Nov
Best places to see sea turtles:
- Parque Nacional Marino Las Baulas
- This national park was established in 1990 to protect turtles from poachers. You can see them on Playa Grande in Oct – May laying their eggs. You have to reserve in advance for a spot and it is for turtle viewing only.
- Tortuguero National Park
- This national park is in the northeast corner of Limon and this beach is one of the most important for the endangered green turtle nesting sites in the Western Hemisphere. Turtles come here from the months of July to October to hatch their eggs.
- This site is one of the most important for sea turtle egg hatching.
- Santa Rosa National Park
- This national park is in Guanacaste and is the oldest in the province. There are two beaches in this park that are the most important for sea turtle nesting, Naranjo and Nancite.
- You can see in one night, hundreds of turtles coming to shore to lay their eggs and it is one of two sites where the Pacific Ridley sea turtles pass through in Costa Rica.
- Ostional Wildlife Refuge
- This park is also located in Guanacaste and is a major nesting ground for the Olive Ridley turtle. You can pay for a tour to go with a guide (highly recommended) after 6 pm since turtles come at night.
- Gulf of Papagayo
- It is common during July – September to see turtles mating in the water. Mostly Olive Ridley sea turtles as they then nest in Playa Naranjo or Ostional.
- Cano Island
- It is common to see turtles, particularly juveniles at Cano Island and you can snorkel with them.
The best time to come see the turtles on shore is during arribadas (the last quarter moon of each month during green season). This occurs at Ostional and Playa Naranjo for the Olive Ridley Sea Turtles.
These are the main national parks where you can view turtles but there are many more places.
- Osa Peninsula and Corcovado: Many of the beaches are nesting sites for 3 species of turtles.
- Camaronal Wildlife Refuge: Located south of Samara in Guanacaste. 3 species come here to nest between May – Nov.
- Gandoca Manzanillo Wildlife Refuge: Located on the south Caribbean coast. Leatherback turtles nest here from March – May.
- Cahuita National Park:On the Atlantic coast in Limon. 4 species of turtle nest are here between July – Oct, March – July and nest from Feb- May.
- Finca Baru Wildlife Refuge: Located on the South Pacific coast. Is a nesting site for Olive Ridley turtles from July – Nov.
The most sought after animal to see are sloths in Costa Rica. These guys are a bit hard to see out in the wild however since they blend in so well with their surroundings. The sloths in Costa Rica are the two-fingered and three-fingered.
Sloths are unable to survive outside the tropical rain forests of C. and S. America but they do astonishingly well inside. Some species are endangered or critically endangered since they live most of their lives in the trees eating leaves among other things. Deforestation has become one of the main reasons for their decline in S. America.
Best time to see them: All year long. Rainy season better than dry season since all the trees and flora flourish during this time.
Best places to see them: There are sanctuaries you can visit and many national parks where they live on both sides of the country. Guanacaste is not the best place to see sloths due to the dry heat so if you are staying at the beaches in Guanacaste like Samara, Tamarindo or Coco, you will need to travel to see sloths either to Arenal, Bijagua or visit an animal sanctuary. **Please do your research on animal sanctuaries, any sanctuary that allows you to touch, hold or pick up sloths is not a good one as that is very harmful to the animal.**
Animal rescue centers or sanctuaries where you can see sloths are Jaguar Rescue Center, Toucan Rescue Ranch and Diamante.
- You must go on a night walk to see sloths as only 2-fingered sloths are found in Monteverde and they are largely nocturnal.
- Though not common in the national park, you can see sloths in the forests around Arenal and La Fortuna.
- Manuel Antonio National Park
- In Manuel Antonio National Park, you can easily see sloths. The forests are a more suitable habitat for sloths than the dry heat in Northern Guanacaste. You can see both two and three-fingered sloths and it’s one of the prime spots to see sloths in the wild.
- If you’re a guest at Tulemar Vacation Rentals and Resort, you can go on a sloth walk with the Sloth Institute. There are a ton of sloths in that property.
- Corcovado National Park
- This national park is also located in Puntarenas and is considered one of the most biologically diverse places on earth. All sorts of Costa Rica wildlife are seen in this national park, including sloths.
- Dominical and Uvita
- It is common to see sloths even by the side of the road up in the trees or even crossing the road!
- Puerto Viejo
- The Caribbean side is excellent to see sloths as you can see both and they are very common. You can also see sloths crossing the road here.
- Osa Peninsula
Four different species of monkeys are in Costa Rica: White-face Capuchin monkeys, Howler monkeys, Squirrel monkeys and Spider monkeys. The spider monkey is endangered and two species of squirrel monkey are listed as vulnerable. The howler monkey population has been declining the past few years due to deforestation and electrocution by power lines.
Best time to see them: All year round
Best places to see them:
Corcovado National Park is the only park where you can find all four species of monkeys here and all four are commonly seen in the Osa Peninsula.
Squirrel monkeys are only found in the southern part of Costa Rica such as Corcovado and Manuel Antonio National Park. Howlers and white face monkeys can be seen all throughout Costa Rica. In Manuel Antonio National Park, white face monkeys are famous for stealing food and aren’t shy with humans (please don’t feed them).
You can read more about monkeys in Costa Rica.
Birdwatchers, get out your binoculars! 6 different species of toucans are found in the rain forests of Costa Rica. The Black-mandibled toucan is the largest of the six and all can be seen in the tropical and subtropical forests.
Where you can toucans, you can also see macaws as the two birds commonly found in the same areas.
Best time to see them: All year long
Best places to see them: These colorful creatures are a very important part of the rain forest ecosystem and being so flashy and having distinct calls, it is fairly easy to spot them while hiking in the national parks.
Carara National Park is a great place to see the toucans and scarlet macaws since it has more primary rain forest.
All the toucans live in different parts of the country. Keel-billed toucans are more common in the high elevation and the Caribbean, Black Mandibuled Toucans are found in the South Pacific, Caribbean and Arenal and the Emerald Toucanet is only in the high elevation areas. The Fiery billed aracari toucan is found only in the South Pacific. Make sure to do your research if you are looking for a specific toucan.
Many beaches on both Pacific and Caribbean are very good for snorkeling. You’ll see all types of tropical fish such as butterfly fish, angel fish, pufferfish, and much more.
If you’re looking to do some sport fishing or see some bill fish, you can hire a sport fishing company so you can experience the excitement of catching a rooster fish, sail fish or even a marlin. Or you can just grab a pole and fish like a local!
There is so much wildlife in Costa Rica that it’ll be impossible for me to list them all. These are the main animals people want to see the most but some other common animals in Costa Rica are peccaries, coatis, anteaters, snakes, insects, frogs, sting rays, sharks, crocodiles, deer, raccoons, bats and jungle cats.

If you want to read up or be able to identify Costa Rica wildlife, I suggest getting a pocket/field guide or a book. There are some excellent ones out there with all the information you ever wanted to know about these animals.
Also do NOT forget to bring your zoom lens! We currently use a Canon 100-400 mm lens and a 1.4 extender on a crop Canon 80d which works great for wildlife shots. Sigma and Tamron both have a 150-600 mm lens which is excellent as well.
Here are some of the books and field guides we use. We also highly recommend hiring a guide as they have trained eyes and know how to find wildlife. Especially if you are a photographer, you will need a guide to find the animal you want to photograph.
