Are There Squirrel Monkeys in Costa Rica? Best Places & Guide

You can spot squirrel monkeys in Costa Rica, but honestly, only in a few spots along the Pacific lowlands. The Central American squirrel monkey hangs out in small rainforest pockets, so if you’re hoping to see one in the wild, you’ll need to pick your locations and timing carefully.

Plan to walk forest trails near the central and southern Pacific coast, where these quick, lively monkeys live. The rest of this article covers their habitat, the best places to spot them, and a few tips to boost your chances on your trip.

Squirrel Monkeys in Costa Rica: Species, Range, and Habitat

Squirrel monkeys in Costa Rica are tiny, noisy, and stick to the Pacific side. Let’s look at which species lives here, where they hang out, and how they’re different from other monkeys in Costa Rica.

Central American Squirrel Monkey: Saimiri oerstedii

The Central American squirrel monkey (Saimiri oerstedii) is the only squirrel monkey you’ll find native to Costa Rica. Adults weigh around 1 kg and measure about 30 cm in body length, with tails that stretch another 39 cm or so.

You’ll spot their reddish or orange backs and pale faces with those distinct dark eye-rims.

They travel in troops, sometimes just a few dozen, but groups can reach up to 100. You’ll probably hear their high-pitched chirps and whistles as they move or warn each other. The species has subspecies too, like the grey-crowned red-backed type locals call mono tití near Quepos and Manuel Antonio.

Where Squirrel Monkeys Live: Pacific Coast, Rainforests, and Secondary Forests

Squirrel monkeys stick to Costa Rica’s Pacific lowland coast and a small part of Panama next door. You can find steady populations on the Osa Peninsula and some scattered groups near Manuel Antonio and Quepos.

Their range is way more fragmented and limited than other Costa Rican monkeys.

They like lowland tropical rainforest and secondary forest—those areas that grow back after being cleared or disturbed. You’ll often see them sleeping in palm crowns, or moving through the lower and middle canopy looking for fruit and insects.

Human threats are a problem: development, roads, and palm oil plantations chop up their habitat and split up troops. For a map of where they live, check the overview of Costa Rican monkey species (https://en.wikipedia.org/wiki/List_of_Costa_Rican_monkey_species).

Key Differences From Other Costa Rican Monkey Species

Compared to howler, capuchin, and spider monkeys, squirrel monkeys are much smaller and eat more insects. You’ll recognize them by their size, fast movements, and those sharp, high-pitched calls.

Howlers (Alouatta) are bigger and make deep roars. Capuchins (Cebus/Cebus imitator) have sturdier builds and even use tools. Spider monkeys (Ateles) have long limbs and prehensile tails.

Squirrel monkeys like the lower canopy and secondary growth, which spider monkeys usually avoid—they stick to the tall, continuous forest. Their limited Pacific range makes them more vulnerable than the widespread white-faced capuchin and howler.

If you want to find mono tití or Saimiri oerstedii, focus on protected coastal parks and the last forest fragments.

Best Places to Spot Squirrel Monkeys and Wildlife Watching Tips

You’ll find squirrel monkeys in just a handful of key Pacific spots. Plan for early mornings, guided walks, and stick to protected areas to up your chances of seeing them.

Manuel Antonio National Park: Easy Access & Beach Trails

Manuel Antonio National Park sits right on the central Pacific coast and has short, clearly marked trails that often lead you to squirrel monkeys. Walk the shaded trails in the morning; monkeys get active near sunrise and again before late afternoon.

Some trails reach little beaches, so you might catch monkeys in the trees above the sand. Binoculars help, and it’s smart to wear quiet, neutral colors so you don’t scare them off.

Park guides know where the troops usually hang out and can recognize their calls. If you hire a certified guide, you’re much more likely to spot squirrel monkeys, capuchins, sloths, and toucans—all while following park rules.

Manuel Antonio gets busy in the dry season (December to April), so showing up early really pays off.

Osa Peninsula & Corcovado National Park: Wild Encounters

Corcovado, out on the Osa Peninsula, is probably the top spot in Costa Rica to see squirrel monkeys in a truly wild setting. Trails are longer and rougher, so you’ll want to prepare for all-day hikes and maybe muddy paths, depending on the season.

You’ll also run into howler monkeys, spider monkeys, sloths, and a bunch of birds like toucans.

Hire a local guide or join a ranger-led trek to safely reach remote parts of Corcovado. You’ll need water, rain gear, and definitely insect repellent.

If you’re hoping for up-close encounters, stay at one of the Osa Peninsula lodges—they often lead early morning walks into protected areas and wildlife refuges.

Other Top Destinations: Drake Bay, Tortuguero, and Wildlife Refuges

Drake Bay and nearby coastal forests on the Osa Peninsula often have squirrel monkeys and plenty of other wildlife. Small boat rides and short hikes make Drake Bay a solid base for guided trips.

Tortuguero National Park sits on the Caribbean side and doesn’t have squirrel monkeys, but you can see sloths, toucans, iguanas, and loads of waterbirds there.

Look for protected wildlife refuges and private reserves along the Pacific coast if you want quieter birding and primate watching. These smaller refuges can offer a more peaceful experience than the main parks.

Keep an eye on the seasons: dry season (December to April) usually means easier trails and better road access.

Responsible Wildlife Viewing: Safety and Conservation

Always keep several meters away from wild animals. Seriously, don’t try feeding or touching squirrel monkeys, capuchins, or sloths.

Feeding them messes with their natural habits and might even spread disease. Want a good photo? Just grab a zoom lens or some binoculars instead of getting close.

Stick to marked trails. Listen to your guide—they know how to keep habitats in places like Manuel Antonio and Corcovado safe.

Pay attention to park rules about group size and noise. During the dry season, try not to trample plants near beaches or trails.

Support local conservation efforts by hiring certified guides and paying park fees. That money goes straight to protecting these wild spaces and the creatures living there.
