Typically appearing as a strong, magnificent stallion or a gentle, lost pony, the kelpie was a malevolent shapeshifting spirit that haunted the lochs (lakes) and deep rivers of the Scottish Highlands. With the legendary strength of 10 horses and a wet, dripping mane, its tail crashed like thunder when it hit the water.

The kelpie tricked the vulnerable—weary travelers, women, and children—into riding it. But when they mounted the creature, its glue-like coat trapped them, making dismounting impossible. The kelpie then plunged into the water, drowning its victims. After devouring them, it left only a kidney or a liver on the bank.

In some legends, the kelpie shapeshifts into a handsome man to lure a woman, or into a beautiful woman to lure a man, or into an old man to lure young and old. But there are few giveaways: seaweed or sand in the kelpie’s hair; horseshoes instead of boots; and reversed hooves.

An Aberdeenshire variation portrays the kelpie as a horse with a mane of serpents, while its counterpart along the River Spey in northeast Scotland is white and entices its victims with song.

Nearly every Scottish body of water has a kelpie story associated with it. Legends probably evolved to enforce moral standards or to explain the disappearance of people who had accidentally fallen into the water and drowned. Parents may have used the story to warn children to stay away from the turbulent water, or to discourage young women from taking up with strange young men.

The Legend of Eight Boys

According to one story, eight boys in Thurso skipped church one Sunday, hoping to see this ferocious beast. As they played alongside a nearby loch, they heard. Expecting to encounter a monster, they froze. Instead, a gentle stallion knelt beside them, urging them to hop on. One by one, the children clambered on its back, which grew longer as each one jumped on.

One child, whose mother had terrified him with kelpie legends, hesitated. Longing to join his friends for a fun ride on the gentle horse, he touched the horse’s neck with one finger.  Instantly filled with a premonition of drowning, he tried to yank his hand away from the kelpie’s coat, but his finger was stuck. So, took out a pocket knife and sliced off the tip of his finger. Rearing in rage, the kelpie disappeared into the water with seven children and one fingertip. Only a few entrails were later found.

The Hour Has Come …

In another story, a group of farmers harvesting barley alongside River Conon in the Scottish Highlands heard a foreboding call from the river.

“The hour has come,” a voice called, “but not the man.”

They saw an immense black horse with a demonic stare standing in the river between two dark pools. Then, in a blinding flash, it disappeared, leaving the men terrified.

Not knowing if the call was a threat or a warning, they resumed their work with trepidation. At day’s end, as they headed home, they spotted a man in the distance heading toward the river.

“Halt,” they called. “Turn back to avoid the kelpie!”

But he ignored their warnings as superstition.

Convinced of pending doom, and determined to save the man—whether he wanted to be saved or not—they dragged him into an old church and locked him in. He shouted in rage to be let go. When they presumed that the river was safe from kelpies, they entered the church to set him free. But he was dead, drowned in a trough of water.

Seductress of Conon

Like their male kelpies, even when assuming the guise of a gorgeous woman, female kelpies could not hide their true nature: They had sand, pond weeds, or kelp woven into their hair, and their feet remained as horse hooves.

Unlike their male counterparts, solitary, long-haired female kelpies sat sadly on rivers and in lochs, relying on enchantment and beauty rather than glue to overpower and drown unsuspecting victims.

Along the southern banks of the River Conon stood the historic country estate called Conon House. Lurking along the marshy banks of the river was the Seductress of Conon House. Rather than luring her victims in the guise of a harmless creature, this green-clad kelpie would jump out of the water with a withered face and terrifying scowl to overpower and drown any man or boy who crossed her path.

The Kelpie of Loch Garve

One day a builder on the shores of Loch Garve in the Scottish Highlands found a beautiful black horse gazing near his cottage. With no saddle or rider in sight, the builder thought it was his lucky day, so he jumped upon the horse’s back.

As the horse immediately raced toward Loch Garve, the builder realized that the horse was a kelpie. He screamed for help. Alas, the kelpie plunged into the water. The man held his breath until his lungs were about to burst. When he finally took a breath, he was stunned to discover that he could breathe underwater.

“Fear not,” the kelpie said. “You have been brought here to help me solve a specific problem.”

He explained that his wife was not happy living at the bottom of the loch. She was always cold and tired of eating raw fish.

“She needs a roaring fire, and you are a master builder. I want you to build a huge fireplace with a chimney that reaches just below the surface of the water.”

The builder got to work and constructed a sturdy fireplace to the kelpie’s specifications. When fire roared in the hearth, and the wife was happy, the kelpie returned the builder to the shore with the promise of payment.

“From this day forward, I will give you fresh fish whenever you leave an empty bucket by the shore.”

Long after the builder died, the chimney has remained. To this day, when snow covers Lock Garve, there is always one spot that remains unfrozen directly over the kelpie’s chimney.

Controlling the Beast

Just as with werewolves, some legends proclaim that a kelpie can be killed by shooting it with a silver bullet. But a kelpie has an inherent weakness as well—its bridle, otherwise known as its necklace. If the creature appeared without any tack, or if you were able to take control of the bridle, you could control the beast and force it to work for you.

From Barra, an island in the Outer Hebrides, comes a tale of a lonely kelpie that transformed itself into a handsome young man because he fell in love with a pretty young woman. But she recognized him as a kelpie and removed his silver necklace while he slept. The kelpie immediately reverted to its equine form, and the woman took the kelpie home to her father’s farm. After working for a year, the girl rode the kelpie to the village’s wise man.

“Return the necklace,” the old man told her. She obliged. Instantly, the handsome young man reappeared. The old man turned his attention to the shapeshifter and asked, “Do you wish to remain a kelpie or become mortal?”

The kelpie turned to the young woman.

“If I were a man,” he asked the lass, “Would you marry me?”

She agreed, and they lived happily ever after.

Pop Culture and Landmarks

One-hundred-foot-tall steel sculptures, known as The Kelpies, were created by Andy Scott in 2013 in Falkirk, Scotland. Weighing more than 300 tons each, they were inspired by the Clydesdale horses.

The creature is also widely featured in the Harry Potter and Fantastic Beasts franchises.

The kelpie is also similar to the Norwegian Nix, which features prominently in The Nix, the 2016 novel by Nathan Hill.
