There’s something undeniably eerie about abandoned islands. With their history steeped in mystery, death, and decay, these islands remain some of the most unsettling places on Earth.
Whether it’s the site of ancient plagues, deadly creatures, or historical horrors, these islands are best left to the imagination, if not your nightmares. Let’s dive into the most chilling abandoned islands that continue to haunt the world.
Poveglia Island, Italy

Poveglia Island, located between Venice and Lido, is infamous for its dark past. Originally inhabited by people fleeing barbarian invasions in 421 CE, it soon became a quarantine zone during the bubonic plague in 1348. Thousands of plague victims were exiled to this island, where they met their inevitable deaths.
The island’s macabre history didn’t end there. In 1630, the plague returned, and once again, Poveglia was used as a dumping ground for the dead. Napoleon Bonaparte later turned the island into a military depot, utilizing its isolation to his advantage.
In 1922, a mental asylum was built, and the island’s horrifying past was renewed. A cruel doctor, rumored to have tortured patients and performed horrific experiments, met his demise by falling from the asylum’s bell tower.
Since then, the island has been abandoned, its grounds covered in dense greenery and crumbling buildings. The lingering fear of over 160,000 deaths still echoes through its desolate landscape, making it one of the most unnerving abandoned locations in the world.
Ilha da Queimada Grande, Brazil
Just off the coast of São Paulo, Brazil, lies the picturesque yet deadly Ilha da Queimada Grande. At first glance, it seems like a tropical paradise, but it harbors one of the deadliest creatures on Earth: the golden lancehead viper.
The island is home to 2,000 to 4,000 of these venomous snakes, whose bite can kill a human within an hour. The Brazilian government has forbidden public access, and only scientists are allowed to visit the island to study the species and their venom for medical purposes.
Local legends tell stories of pirates using the island’s snakes to protect their hidden treasure, but the true cause is evolutionary. Isolated by rising sea levels, the snakes evolved to become more dangerous to catch migratory birds for food.
Due to the threat of snakebite, the government ensures that a doctor accompanies any authorized visitors, although the venom still has the potential to cause permanent damage.
Ross Island, India
Ross Island, located in the Andaman Islands, India, holds a grim history. In the 19th century, it became the site of a British penal colony, where prisoners were subjected to forced labor in the jungle to build mansions, churches, and other structures for the colonizers.
The island was a symbol of British cruelty, as prisoners died from diseases like malaria, cholera, and dysentery, often used as experimental subjects in trials for new medications.
The horror continued when a magnitude 8.1 earthquake struck in 1941, killing over 3,000 civilians. During WWII, the Japanese used the island as a military base, further adding to its tragic history.
After India reclaimed the island in 1945, it was abandoned, and nature began to reclaim it. Today, the crumbling structures and overgrown ruins tell the story of a dark and twisted past.
Discovery Island, USA
Tucked away in the waters off the coast of Florida, Discovery Island was once a popular attraction at Walt Disney World, offering visitors a chance to explore exotic birds and tropical wildlife.
However, by 1999, the island was abandoned as visitor interest waned and Animal Kingdom became the focal point of Disney’s animal-related attractions. The island, left to rot, became overtaken by nature.
Though the island’s bird population was relocated to Animal Kingdom, some structures, like the animal hospital, remain intact.
Despite this, Disney now employs security guards to prevent trespassers from exploring the island, fueling rumors about its future. The mystery surrounding the island, coupled with its eerie emptiness, adds to its haunted legacy.
Hashima Island, Japan

Hashima Island, also known as Gunkanjima or “Battleship Island,” sits off the coast of Nagasaki. This once-thriving coal mining island became a booming metropolis in the 20th century, home to over 5,000 people.
However, the island’s history is marred by the exploitation of laborers, especially during WWII, when over 1,000 Korean and Chinese prisoners were forced into grueling work under inhumane conditions.
After the coal mines were depleted, the island was abandoned in the 1970s, and nature slowly overtook the industrial structures.
Hashima Island’s chilling past is now a tourist attraction, though many visitors report a lingering sense of unease as they walk through its empty, crumbling buildings. The eerie silence and decaying infrastructure paint a haunting picture of the island’s past.
McNabs Island, Canada
McNabs Island, located in the Halifax Harbor off the coast of Canada, has a history that dates back to the 1780s.
After being settled by Peter McNab and his family, the island became a site of fishing operations, military forts, and even a Prohibition-era bootleg soda pop factory.
Its most unsettling feature, however, is its graveyard of cholera victims, as well as the remains of shipwrecks scattered across the island.
The island is largely forgotten by the public, with no tours or official attractions. The decaying structures, along with the eerie remains of its past, create an unsettling atmosphere. Though the island is off-limits to most, a few local fishermen still offer trips to the island, where the mysteries of its past remain alive.
