Haunted Jungles Are the Surprising Reason to Visit This Country

Go ahead, grab your machete, and let’s go for a jungle jaunt.

The Costa Rican jungle is one of the lushest, most biodiverse places on earth. It teems with life and energy, with rhythm and movement, with plants and animals. It’s also … kinda eerie. 

The jungles of Costa Rica have long occupied a strange space between the natural and the supernatural. Even today, it still feels mysterious. For centuries, explorers, settlers, and Indigenous communities have told stories about the strange sounds, lights, and spirits that seem to inhabit the deep green interior of Costa Rica. The result is a landscape where folklore and ecology intertwine so closely that it can be difficult to tell where myth ends and reality begins.

Eerie Nature

Part of the mystery comes from the jungle itself. Costa Rica’s rainforests are among the most biologically dense ecosystems on Earth. In protected areas such as Corcovado National Park, scientists estimate that thousands of species occupy a single square mile. Inside, there’s an orchestra of strange sounds: insects buzz, frogs chirp, birds shriek, and unseen animals rustle through the leaves. Waterfalls churn and rivers babble in the distance. Early explorers entering these forests for the first time had no context for the sounds they heard. To them, the jungle often seemed haunted.

One of the most famous explanations for the “voices” of the rainforest is the roar of the Mantled howler monkey. These monkeys possess an enlarged throat bone that acts like a resonating chamber, allowing their calls to carry for miles. At dawn and dusk, the jungle can erupt with deep, rolling cries. To someone unfamiliar with tropical wildlife, the sound resembles distant chanting or even human screaming. Spanish explorers in the 16th century wrote in journals about “demons crying out in the trees,” convinced the forest contained supernatural presences. In reality, the howler monkeys were simply announcing their territory to neighboring troops.

In the jungle, it is easy to understand how stories of ghosts, spirits, and mysterious creatures came about. In a landscape where sight is limited but sound and sensation are everywhere, imagination and storytelling fill the gaps.

Eerie Legends

Costa Rican folklore reflects these eerie experiences. One of the most famous legends is that of La Segua, a ghostly woman said to appear on lonely roads. According to the story, she first appears as a beautiful traveler asking for a ride. Only when the victim looks closely does her face transform into the skull of a horse–right before she kills them. The legend is often told as a warning against arrogance or unfaithfulness (La Segua was said to be a woman scorned), but its setting is telling: the encounter almost always happens along remote jungle paths where visibility is poor, and fear already runs high.

Another legend, shared across parts of Central America, is the tale of the Cadejo. This creature is described as a supernatural dog that stalks travelers at night. Some versions speak of two Cadejos: a white one that protects the innocent and an evil black one sent by the devil to hunt and kill. Storytellers claim that claws click on the trail behind them, though when they turn around, nothing is visible. It’s an unsettling experience moving through a dense forest where animals often remain unseen but are constantly audible.

Perhaps the most haunting legend associated with the region is the story of La Llorona, the Weeping Woman, a malevolent spirit said to wander rivers searching for her drowned children. In Costa Rica, the tale often centers around jungle waterways, where the sound of wind moving through mangroves or night birds calling across the water can resemble distant crying. The eerie acoustics of the rainforest amplify such sounds, turning ordinary animal calls into something far more unsettling.

Eerie Exploration

You arrive thinking you’re going for a nice walk. Maybe a peaceful hike. Perhaps you’ll see a bird, take a photo, and feel spiritually renewed. And you will. All within an ecostyatem that pays you absolutely no mind. And that can be unnerving, though incredibly rewarding. So go exploring–there’s so much to see in the wilds of the jungle. 

Start with the obvious: wildlife watching. The crowning jewel of Costa Rica’s jungles is the wildlife hiding in plain sight. Let’s start with the littlest creatures in massive numbers: the bugs. Army ants live in entire societies. Cicadas are louder than a Mack truck. Mosquitos never quit. The bugs aren’t usually the cutest of the wildlife you’ll see, but they are extremely easy to spot. 

Birding is extremely popular due to the beauties hanging out on the branches above you: red-tailed macaws, rainbow-beaked toucans, and brightly colored parrots. Who else is hanging out in the trees? The howler monkeys, of course, but also the adorably chill three-toed sloth. In the rivers, find something slightly less cuddly: 14-20 foot crocodiles gathering in the rivers that snake through the jungle. Friendlier lizards and lazy iguanas skitter about the paths. 

Suspension bridges abound. Sure, they’re feats of modern engineering, but when you walk across them, they move and shake. And the last thing you want to feel when you are walking across a bridge is the absolute nothingness keeping you tethered to the earth. But that’s the beauty of the Costa Rican jungle. Even dangling from the sky, the earth is all around you. Reach out and touch a tree top. 

Eerie Beauty 

Despite the legends, the Costa Rican rainforest is not truly haunted. Its mysteries arise from a combination of biology, climate, and human imagination. The forest is loud because so many species live there. It whispers because sound travels strangely beneath the canopy. It glows at night because insects and fungi produce light. What once seemed supernatural is often simply nature behaving in ways unfamiliar to visitors. The same natural forces that make the Costa Rican jungle one of the most vibrant ecosystems on Earth also make it one of the most mysterious. Even now, the jungle continues to inspire stories that blur the line between science and legend.

Tell your own stories of exploring the jungle by staying in Santa Lucia Jungle Hacienda in Puntarenas, Costa Rica. The hotel abuts the Carara National Park, which hosts a variety of aforementioned wildlife as well as 15 pre-Columbian archaeological sites belonging to the archaeological area of the Central Region of Costa Rica. Modern comfort meets blissed out serenity with creature comforts like a riverside pool and separate kids area, spa, two restaurants, church, and hiking trails through the lush grounds (as well as knowledgeable guides to take you).
