Then came the moment that changed everything.

The man would lean closer, drawn by her beauty, perhaps hoping for a kiss. And that was when the illusion shattered.

Where a beautiful woman had been sitting beside him, there was suddenly something ripped from the deepest pit of a nightmare: the body of a woman crowned with a rotting horse skull. Her red eyes burned with an unnatural glow. The air filled with the stench of death, as though a grave had split open right beside him.

The creature that had seemed so inviting only moments before now stared at him with the dead, hollow gaze of something that had no business walking among the living.

Yeah, not exactly the dream date.

In most versions of the legend, the man never makes it home. The following morning, someone finds his body lying beside the road, his eyes wide open and his face frozen in an expression of absolute terror.

Whatever he witnessed in those final moments is something no living person can fully explain. The few who survive an encounter with La Segua, are said to suffer a fate almost as horrifying. They spend the rest of their lives paralyzed, unable to move or speak about what they saw, as if the creature has taken something from them that no doctor, priest, or healer can ever restore.

And Costa Rica is far from the only country haunted by the legend of a beautiful woman with a monstrous secret. Across Central America, similar figures appear under different names. In Mexico, she is known as X’tabay; in Guatemala and El Salvador, she is called Siguanaba; and in Belize and Honduras, she is known as Sucia.

Each country has its own version of the mysterious woman who lures unsuspecting victims toward disaster. But Costa Rica has made La Segua, its own, shaping the legend into a uniquely chilling tale that continues to haunt the country’s imagination.

In writer Elías Zeledón-Cartín’s book Leyendas Costarricenses (Costa Rican Legends), La Segua, is described as breathtakingly beautiful, with long black curls, deep red eyes, lips as red as blood, and a siren’s voice capable of melting any man’s heart. Sometimes she wears black, blending into the shadows of the night; other times, she appears dressed in white or pink, her face concealed beneath a delicate veil. She looks less like a creature of terror than a woman stepping out of a dream.

And that is precisely what makes her so dangerous.

Because the man who encounters her sees what he wants to see. He sees beauty. He sees an opportunity. He sees a woman who might smile at him, whisper to him, or lean toward him in the darkness.

And then...

Well, you know what happens next.

Some versions of the story say La Segua, appears as a young girl crying beside a road or river, her sobs drifting through the darkness as she begs for help. She may look frightened, lost, and utterly alone, a helpless stranger whom any decent person would feel compelled to assist.

But the moment a kindhearted man stops and reaches out to her, the horror begins. Her face changes. Her features twist. The beautiful illusion falls away, revealing the nightmare hidden beneath it. By the time her victim understands the trap, it may already be too late.

Other stories warn that you can sense La Segua,’s presence before you ever see her. Perhaps you hear a whisper carried on the wind when there is no one nearby. Perhaps a low growl rises from the darkness behind you, even though the road is empty. Or perhaps you hear laughter, strange, unnatural laughter that seems to crawl out of hell itself, growing louder as you search desperately for its source.

And sometimes, the most frightening sound of all is the sudden silence that follows.

But where did she come from? What could turn a beautiful woman into such a terrifying creature? And why does she continue to appear along the roads of Costa Rica, waiting for men who may never realize what they have encountered until they look into her face?

Her beauty had become her greatest source of pride, and she dreamed of escaping her humble life by winning the affection of a wealthy Spanish man known for his bad reputation. When her mother tried to stop her from pursuing him, warning her against the man and the danger he represented, the young woman responded with a terrible act of defiance: she cursed her own mother.

According to the tale, a witch appeared, furious at the girl's cruelty and arrogance. Rather than allowing her to escape the consequences of her actions, the witch condemned her to wander the world forever, trapped between beauty and monstrosity.

“Men will come close,” the witch warned, “but your face will drive them away.”

And so the curse took hold. La Segua, would remain beautiful enough to attract men, yet her true face would reveal itself at the very moment they came closest to her.

She would spend eternity drawing her victims toward her, only to become the thing they feared most. Her beauty would be her bait, her monstrous face her punishment, and the lonely roads of the night her prison.

But not every version of the legend paints La Segua, as a vain woman punished for her pride.

Another tale turns the story into something darker and more tragic. In this version, she was a woman who had been wronged, betrayed, and abused by a wealthy lover.

The man had taken advantage of her trust and shattered her life, leaving her to suffer the consequences of his cruelty. Her heartbreak became something far more terrible than grief.

Cursed by the pain she endured, she now roams the night, hunting men who treat women like playthings.

In this telling, La Segua, is more than a monster. She is the embodiment of betrayal, rage, and vengeance, a restless figure who turns the cruelty inflicted upon her into a curse for others.

Whether she is a victim seeking revenge or a sinner condemned to eternal punishment, the result is the same: somewhere out there, along a lonely road, she may still be waiting.

In Guanacaste, locals swear that La Segua, continues to appear at community dances, where the music plays late into the night and the crowds gather beneath the warm glow of the lights. She arrives looking beautiful and flirtatious, moving through the festivities as if she belongs there. Men notice her. They approach her. They become captivated by her smile and the promise of a night they will never forget.

And perhaps they won't.

According to the legend, La Segua, eventually lures a man away from the music and into the darkness beneath the trees. The sounds of the celebration fade behind them, replaced by the rustling leaves and the distant calls of nocturnal creatures. There, away from the watching eyes of the crowd, she draws him close.

Then comes the kiss.

The dance continues in the distance, the music plays on, and the night swallows whatever happens beneath the trees. By morning, the man may be dead, or he may return to the world of the living, carrying a terror so profound that he will never again be the person he once was.

The legend of La Segua, even found its way to the big screen. In 1982, Costa Rican filmmaker Antonio Yglesias brought the haunting tale to life in a film written by Alberto Cañas.

The story's journey from oral folklore to cinema helped preserve one of Costa Rica's most enduring legends, giving audiences another way to encounter the mysterious woman who has frightened generations.

A clip from the film still circulates on YouTube's Cine Ficcion Channel, offering a glimpse of how this unsettling piece of Costa Rican folklore was brought to the screen.

So the next time you're driving along a dark road in Costa Rica, far from the city lights, pay attention to the shadows at the edge of the road.

Listen to the wind moving through the trees. Notice the places where the darkness seems just a little too deep.

And if you see a gorgeous woman standing alone by the roadside, waving for a ride, don't assume she's lost. Don't roll down the window. Don't stop to ask if she needs help. And whatever you do, don't lean closer if she smiles at you.

Just keep driving.

Because if the stories are true, you may not get a second chance to discover what is hiding beneath that beautiful face.

And if you happen to glance in your rearview mirror and see her sitting in the back seat, smiling at you with those blood-red lips...

Whatever you do, don't turn around.

Have a Pura Vida Halloween!
