La Fortuna’s rainforest comes alive after dark because nightfall shifts the entire ecosystem into a different rhythm, drawing out wildlife, sounds, and behaviors that stay hidden while the sun is up.
Most people think the rainforest in Costa Rica settles down once the sun disappears, but that’s when an entirely different side of it begins to emerge. Nighttime brings new wildlife, changing conditions, and signs of activity that are easy to miss during the day.
From unfamiliar sounds to tiny creatures hiding among the leaves, here are five things you’ll notice when you experience La Fortuna’s rainforest after dark.

What Happens in La Fortuna’s Rainforest After Sunset?
As daylight fades, the air begins to cool, and a different group of animals starts its day. Frogs begin calling, insects fill the forest with sound, bats fly overhead, and other nocturnal animals come out to feed and move through the trees.
The change happens little by little around twilight, and every evening is different. Rain, temperature, season, and animal behavior all affect what you may see and hear. Wildlife sightings are never guaranteed, but that’s part of the fun—you never know what the rainforest might reveal.
1. A Completely Different Rainforest Sounds
As daytime birds settle down, the rainforest at night fills with new sounds. You may hear frogs, insects, rustling leaves, moving branches, and distant calls from an owl. Animals use these sounds to find mates, protect their territory, and communicate. Surprisingly, some of the loudest calls come from the smallest creatures.
You’ll often hear an animal before you spot it. Pause, look away from your flashlight, and simply listen—you may be surprised by how much is happening around you.
2. A New Group of Animals Taking Over
When the sun sets, many daytime animals find a place to rest while nocturnal wildlife in La Fortuna begins to move through the forest. Some start looking for food, others call to one another, and a few remain almost completely still as they wait for prey.
On a wildlife night walk, you may also spot birds, lizards, and other daytime animals sleeping beneath leaves or on quiet branches. Depending on the conditions and a little luck, you might see:
- Red-eyed tree frogs and glass frogs
- Snakes and lizards
- Bats and owls
- Kinkajous
- Two-toed sloths
- Spiders and insects
- Tropical birds sleeping among the leaves
Just keep in mind that every night is different, so no particular animal sighting is guaranteed.
3. Tiny Creatures Becoming the Main Attraction
Some of the most interesting animals in the Costa Rican rainforest are also the smallest. At night, a flashlight can reveal frogs with translucent skin, spiders sitting beside detailed webs, colorful insects, and lizards that almost disappear against the leaves. Some use bright colors as a warning, while others depend on impressive camouflage to stay hidden.
Frogs, insects, spiders, and other small creatures may become more active when the air is warm and humid, especially after rain. Look closely—you may find that the tiniest sighting becomes one of your favorite moments of the night.
4. Cooler, More Humid Conditions Changing the Forest
After sunset, temperatures usually begin to drop while the air stays humid. Moisture from rain or evening humidity can remain on leaves, bark, soil, and other vegetation, creating good conditions for frogs and other amphibians to become active.
A recent shower may bring more movement, but it never guarantees wildlife sightings. Weather is more than a backdrop in the rainforest—it helps shape how the whole ecosystem behaves. Even in the soft glow of twilight, you can see how closely nature, weather, and adventure come together.
Is a Night Walk in La Fortuna Safe? What to Know
5. Your Own Senses Becoming More Alert
With less light around you, you naturally listen more closely and notice small movements, shapes, and textures. Your flashlight reveals only one part of the forest at a time, allowing guests to focus on details they might miss during the day.
You may notice dripping leaves, eye shine, moving shadows, rustling branches, or calls coming from beyond the trail. Many species depend on the delicate balance of darkness and cover to move safely, so even a familiar path can feel completely new after sunset. The darkness isn’t there to make the walk frightening—it’s part of what makes each discovery feel unexpected.
Day or Night: Is One Rainforest Experience Better?
Neither is better—they simply show you different sides of the rainforest. During the day, you’re more likely to notice broad views, bright colors, and animals that are active in daylight. After dark, your attention shifts to sounds, small details, and nocturnal life in the forest.
| During the day, you may notice… | After dark, you may notice… |
| Colorful birds, butterflies, and other daytime wildlife | Frogs, insects, spiders, bats, and other nocturnal wildlife |
| Monkeys and birds moving through the canopy | Kinkajous, two-toed sloths, and other animals moving among the trees |
| Wide views of the forest and surrounding landscape | Small details revealed one at a time by flashlight |
| Animals feeding, flying, and interacting in daylight | Animals hunting, calling, feeding, or settling down to rest |
| Bright colors and clearer views through the trees | Eye shine, camouflage, shadows, and sounds beyond the trail |
If you’re already visiting during the day, a night walk won’t feel like a repeat. It can help you experience wildlife and behaviors you may otherwise miss. Of course, both visits depend on the weather, natural conditions, and a little luck, so no particular sighting is guaranteed.
Twilight or Night Walk: Which Should You Choose?
The best choice depends on how you’d like to experience the rainforest after sunset. A twilight walk lets you watch the transition unfold, while a night walk takes you straight into the full after-dark experience.
Choose a Twilight Walk to Watch the Change Happen
A twilight walk begins while there’s still some natural light, so you can watch the rainforest shift from day to night. You may see daytime animals settling down as nocturnal species begin to emerge and the sounds around you start to change.
It’s a great option if you want to experience both sides of the rainforest or would feel more comfortable starting before it gets completely dark.
Choose a Night Walk for the Full After-Dark Experience
A night walk begins once darkness has settled and nighttime activity is underway. Your attention turns to nocturnal wildlife, calls coming from the forest, and the small details revealed by a flashlight.
Mistico’s experienced guides know where to look and how to spot signs of wildlife that are easy to miss on your own. They can also help you understand the animals and behaviors you encounter along the way.
