Yes, you can see sloths at night in La Fortuna. In fact, Hoffmann’s two-toed sloths are mostly nocturnal, so nighttime may give you the chance to see one feeding or moving through the trees.
Still, sloths can be surprisingly difficult to find. They often stay high in the canopy, blend into the leaves, and behave differently depending on the weather and other natural conditions. Here’s what you should know before setting out to look for them after dark.
Which Sloths Can You See in La Fortuna?
La Fortuna is home to two sloth species, and you may encounter either one among the trees. Here’s how to tell them apart and what you can expect from each when you visit their natural habitat at night.
Hoffmann’s Two-Toed Sloth
Hoffmann’s two-toed sloth is the species most closely linked with nighttime activity. It typically becomes active after sunset, when it may begin feeding or moving slowly through the canopy.
This sloth is larger than the three-toed species and has longer, shaggier fur. As its name suggests, it also has two claws on each front limb.
Brown-Throated Three-Toed Sloth
The brown-throated three-toed sloth is more commonly active during the day, although its routine can change with the weather, environment, and other natural factors. If you find one at night, it may be resting rather than moving through the trees.
It’s generally smaller, with three claws on each front limb, a rounded face, and noticeable markings around the eyes. These features can help guides tell the two species apart, even when the sloth is partly hidden among the leaves.

What Might a Sloth Be Doing After Dark?
Spotting a sloth is always exciting, but seeing one after dark may give you a glimpse of more than its famous sleeping pose. Even in areas where many sloths live, they can be difficult to find from the trail. Your chances of noticing subtle movement are increased significantly when you explore with a naturalist guide who knows what to look for.
Depending on the species and natural conditions, you might find one:
- Feeding on leaves, shoots, or fruit
- Moving carefully between branches
- Climbing higher into the canopy
- Resting among leaves and vines
- Carrying a baby through the trees
Just remember that “active” is relative when it comes to sloths—even one on the move will still take its time. Look beyond how close it is and watch its behavior. Seeing a sloth follow its natural routine can make the encounter even more memorable.

Why Are Sloths Still Difficult to Spot at Night?
Sloths may become more active after dark, but finding one can still take patience. The canopy is sloths’ territory, and their ability to blend into the trees makes them easy to overlook.
They can be difficult to spot because:
- They spend most of their time high in the trees.
- Their fur blends naturally with the canopy.
- Leaves and vines may cover most of their bodies.
- They move so slowly that you may not notice them at first.
- In the dark, you can only search a small part of the canopy at a time.
A sloth can easily look like a dark bundle of leaves until it begins to move. You may even notice a branch shifting before you realize there’s an animal above you.

How Do Guides Find Sloths in the Dark?
Finding a sloth in the dark takes a trained eye. Guides scan the canopy for unusual shapes, slight movements, disturbed leaves, and trees where sloths are known to feed. They may also use flashlights or viewing equipment to examine areas that are difficult to see from the trail.
Their knowledge of local wildlife and sloth behavior helps narrow the search. They can also tell the difference between a sloth and a nest, branch, or thick patch of vegetation—something that isn’t always easy when you’re looking up in the dark.
A night tour can be especially rewarding for wildlife lovers because guides may also point out howler monkeys, a few birds resting in the trees, and other animals along the way. Their experience can improve your chances of noticing wildlife, but no particular sighting is guaranteed.

Is Night or Day Better for Seeing Sloths?
Neither time is always better. Daylight makes the canopy easier to scan, while an evening walk may give you a better chance of seeing a two-toed sloth active after dark. The right choice depends on the kind of experience you want.
| Watching sloths during the day | Watching sloths after dark |
| Daylight makes it easier to scan a wider area of the canopy | Flashlights reveal one smaller section of the canopy at a time |
| Three-toed sloths may be active, while two-toed sloths are often resting | Two-toed sloths may be feeding or moving through the trees |
| Natural light generally makes photography easier | Low light can make photography more challenging |
| You may also see daytime wildlife such as birds and monkeys | You may also encounter frogs, insects, bats, and other nocturnal wildlife |
| Best if you want clearer views of the animal and its surroundings | Best if you want to observe possible after-dark behavior |
Whether you choose daytime or evening sloth tours in Costa Rica, sightings are never guaranteed. Weather, location, canopy cover, and natural animal behavior all influence what you may find.
Can You Photograph Sloths During a Night Walk?
Yes, but taking a clear photo can be challenging. Sloths may be high in the canopy, partly hidden by branches, or moving through an area with very little light.
If you’re using a smartphone, try night mode and avoid excessive digital zoom, which can make the image blurry or grainy. A camera designed for low-light conditions may give you better results. Keep your hands steady, use a railing for support when appropriate, and follow your guide’s instructions about flashlights or other artificial light.
Your photo may not be perfect, but it can still capture a special moment from the walk.
Are Sloth Sightings Guaranteed at Mistico Park?
No, sloth sightings can’t be guaranteed at Mistico Park. Sloths are wild animals, and weather, food availability, movement through the canopy, and natural behavior all affect what you may find on each tour.
Even if you don’t spot sloths, the adventure continues to be fun and intriguing. Along the trail, you may see frogs, reptiles, insects, sleeping birds, kinkajous, and other nocturnal wildlife. Come with a wish list rather than a required checklist, and let the rainforest decide what it wants to show you that evening.
