For most travelers coming from the U.S., there’s one animal at the very top of the Costa Rica bucket list: the sloth. And there’s no better place to check that box than Manuel Antonio, one of the most sloth-dense national parks on the planet. But here’s the catch nobody tells you before you arrive — sloths are masters of hiding in plain sight. This guide covers exactly where to look, when to go, and how to make sure you actually see one instead of walking right past it.

Which Sloths Live in Manuel Antonio?

Manuel Antonio is home to two different sloth species, and knowing the difference changes how — and when — you’ll find them.

Three-toed sloth (Bradypus)

The famous "smiling" sloth with the black mask around its eyes. Three-toed sloths are diurnal, meaning they’re active during the day, which makes them the ones most visitors spot on a morning hike. They love the leaves of the guarumo (cecropia) tree, so those tall, umbrella-shaped trees are prime real estate.

Two-toed sloth (Choloepus)

Larger, shaggier, and nocturnal. Two-toed sloths sleep curled into a ball high in the canopy during the day and come to life after dark. If seeing this species is your goal, a night walk outside the park is your best shot.

Fun fact worth sharing on Instagram: both species grow algae in their fur, which acts as camouflage and even provides extra nutrients. It’s a big reason they blend so perfectly into the canopy.

Best Time to See Sloths in Manuel Antonio

Timing matters more than luck. Here’s what actually works:

  • Time of day: Early morning (7:00–10:00 AM) is the sweet spot for three-toed sloths, when they’re most active and the park is coolest. Late afternoon (3:00–5:00 PM) is a solid second window.
  • Time of year: Sloths are here year-round, but the dry season (December–April) offers clearer canopy views and easier hiking. Green season still delivers — you’ll just want a guide who knows where they’re feeding that week.
  • Day of the week: Manuel Antonio National Park is closed every Tuesday. Plan around it. Entry slots (7:00, 7:30, 10:00 AM, 12:30, 1:00 PM) fill up in high season, so book ahead.

Where to Look: The Sloth Trail

The best-known spot inside the park is Sendero El Perezoso — literally "The Sloth Trail." This flat, accessible path runs parallel to the main trail and is famous for sightings. Keep your eyes up in the treetops, especially in the guarumo trees. Sloths look like a knot of wood or a termite nest, so scan slowly for a patch of fur or the slightest movement.

Why You Really Need a Guide (and a Scope)

Here’s the honest truth: solo visitors spot only 20–30% of the wildlife that’s actually around them. A certified naturalist with a high-powered spotting scope pushes that success rate to 70–95%.

Sloths spend their days motionless and curled up 30 meters above your head, perfectly camouflaged. A trained guide knows which trees they favor, reads the subtle signs, and — this is the part travelers rave about — sets up a scope so you can see the sloth’s face, claws, and even a baby clinging to its belly in crisp detail.

At Wakoo Tours, every guided Manuel Antonio National Park tour goes out with a Swarovski spotting scope and an ICT-certified naturalist who grew up right here. And because a photo through the scope is unbeatable, we send you free 4K photos and video of everything you saw — no upsell, no watermark. For couples and families who want the canopy to themselves, our private VIP wildlife tour includes park entry and pro photography.

Beyond Sloths: What Else You’ll See

Once you’re scanning the canopy with a guide, sloths are just the beginning. Manuel Antonio delivers:

  • White-faced capuchin and squirrel monkeys (the endangered mono tití)
  • Keel-billed and fiery-billed toucans high in the canopy
  • Iguanas, agoutis, and coatis along the trails

Serious birders can go deeper on a dedicated birdwatching tour, and wildlife lovers who want a completely different ecosystem can add the Damas mangrove tour — a boat ride where sloths, monkeys, and caimans line the waterway.

Ready to Meet a Sloth?

Seeing a sloth in the wild is one of those travel moments you’ll talk about for years. Give yourself the best odds: come early, plan around Tuesday’s closure, and go with a local naturalist who can put one in the scope for you. Every Wakoo tour also donates $2 per guest to local kids through Kazan Karate for Kids — so your bucket-list moment gives back, too.
