In the loneliest corner of the Andean highlands of Bolivia and Peru, an Aymaran legend of the Anchanchu or the Abchanchu is said to lurk. Disguised as an elderly man, weary from his travels, he uses people’s goodness to attack and drink their blood.
Come in, come abchanchu, do not do any harm, because Mallcu protects me.
– Chant to keep the monsters at bay
South America is no stranger to terrifying folklore — from weeping women haunting riverbanks to spectral riders in the dead of night their ancient and distinct cultures throughout history has given rise to so many different legends and myths.
One of the more obscure and perhaps not so well known tales chills the blood quite like that of Anchanchu, sometimes known as the Abchanchu, one of Bolivia’s most enduring and sinister legends. For generations, whispers of this deceptive creature have echoed through mountain villages and remote country paths, warning travelers of the horrors that may lurk beneath a frail, human guise.

The Legend of the Bloodthirsty Trickster
At first glance, Anchanchu appears as nothing more than a harmless, elderly man on the side of the road, a hunched figure, weary from travel, moving slowly along the dusty Bolivian roads. His face is lined with age, his clothes tattered from long journeys, and he leans heavily on a walking stick, luring in his unsuspecting victims.
But behind those sorrowful eyes lies a predator.
Anchanchu is a vampire of ancient origin, known for his ability to shapeshift into this deceptive, vulnerable form.
When a kind-hearted passerby offers to assist the seemingly feeble traveler, walking him to safety or providing shelter for the night when he knocks on your door, it’s then that his true, monstrous nature is revealed. The helpless elder transforms into a savage creature, attacking his victim under the cover of darkness and drinking their blood.
Sometimes he lures the victims to his home, promising them a hot meal or anything to get them inside. Other times he plays on your good will, and you bring him home and give a bed for the night. Even if you survive the attack, you will slowly die of the disease the monster leaves you with.
In some versions of the tale, it’s said the vampire leaves little trace of his victims, allowing him to wander from town to town, his terrible secret forever cloaked by his kindly, unassuming appearance.
A Cautionary Tale Born from Bolivia’s Mountains
The legend of Anchanchu is believed to have originated in Bolivia’s Andean highlands, where treacherous mountain paths wind between isolated villages. It is believed that the vampire story comes from an older demon lore of the modern Aymara people in Bolivia and Peru.

In these remote regions, travelers would often rely on the kindness of strangers for survival — a fact that the myth of Anchanchu turns tragically on its head. It used to be confined to small regions until the 18th century, when tales of the monster travelled further.

In the Uyuni region, he comes with the cold, and if you don’t remember to close the windows and lock your doors, he will just walk right in.

For the people of Huancané, it is recommended to not walk at night, specifically after midnight. Anchanchu appears as a red dog around one to three A.M. His appearance is described as being a pudgy, bald, older man.
If you find yourself on a deserted Bolivian road as the sun begins to set, and you happen upon a frail old man limping along the path, remember the warnings of generations past. His weathered smile and pleading eyes may mask ancient hunger, and one act of misplaced kindness could be your last.
Anchanchu or the Abchanchu waits for the charitable, hiding his fangs behind a trembling voice — and the mountains have many lonely places where the missing are never found.
