Ever wanted to explore places where humans once lived but nature said “my turn now”? Abandoned islands are like time capsules of human activity – minus the humans. These eerily beautiful spots went from bustling communities to ghost towns, leaving behind crumbling buildings and seriously good stories.
From plague quarantines to deserted mining towns, these islands are perfect for your inner explorer. Some welcome visitors while others prefer you admire from a safe distance. Ready for a virtual island-hopping adventure to places where “no vacancy” has a whole new meaning? Let’s dive in!
9. Gaiola Island, Italy
Just a stone’s throw from Naples sits a tiny twin-islet with the worst luck ever. Seriously, Gaiola’s like that friend who’s always having a dramatic crisis. Connected by a cute little bridge, this picturesque spot supposedly cursed everyone who owned it – we’re talking mysterious deaths, financial ruin, and all-around bad vibes. The curse reportedly started with a hermit nicknamed “The Wizard” (red flag number one, folks).
Despite its reputation as the real estate equivalent of a black cat, Gaiola’s crystal-clear waters make for amazing snorkeling. Roman ruins lie underwater just offshore, creating a submerged archaeological playground. The abandoned villa slowly crumbles while locals still avoid the area after dark. Can’t really blame them – some real estate deals are just too good to be true!
8. Garden Key, Florida, USA
Fancy visiting America’s most remote fortress? Garden Key sits 70 miles west of Key West and houses Fort Jefferson – a massive brick structure that screams “overcompensating.” With over 16 million bricks, it once held Dr. Samuel Mudd, who fixed up John Wilkes Booth’s leg after he assassinated Lincoln. Talk about a patient you don’t want on your reference list!
Abandoned after yellow fever made everyone rethink island life, it’s now part of Dry Tortugas National Park. Getting there requires a boat or seaplane, and camping means bringing everything – including drinking water. It’s basically camping on hard mode, but with incredible snorkeling and the bragging rights of sleeping where few others dare.
7. Deception Island, Antarctica
If a supervillain designed an island, this would be it. An active volcano with a secret entrance leading to a flooded crater? Come on! This horseshoe-shaped Antarctic hideout hosted whalers and scientists before volcanic tantrums in the late 1960s sent everyone packing.
The island got its name by fooling sailors – looking totally normal until they discovered the hidden entrance to its flooded volcanic center. Today, thrill-seekers come for the planet’s weirdest beach day: bathing in thermal waters while surrounded by Antarctic ice. The black sand beaches littered with rusty equipment and whale bones create the perfect backdrop for your “end of the world” vacation photos.
6. Mamula Island, Montenegro
This tiny fortress island proves that location really is everything in real estate. Built in 1853 as a defensive structure, Mamula took a dark turn during WWII when Mussolini’s forces converted it into a concentration camp. Paradise to nightmare in one easy step.
After the war, everyone understandably wanted nothing to do with it. The contrast between its gorgeous turquoise surroundings and dark history creates serious emotional whiplash. Recently, developers proposed turning it into a luxury resort, which went about as well as you’d expect. Turns out “former concentration camp” and “luxury beach club” don’t belong in the same brochure.
5. Suakin Island, Sudan
Ever built a sandcastle that looked amazing until high tide? That’s basically Suakin Island’s story. Once Africa’s happening port city for nearly 3,000 years, this Red Sea trading hub made the unfortunate choice of building with coral blocks. Gorgeous? Absolutely. Durable when abandoned? Not so much.
When Port Sudan opened in 1909, everyone moved there faster than leaving a bad Airbnb. What makes Suakin fascinating is watching it literally dissolve over time – its beautiful coral buildings slowly returning to the sea. Recent preservation efforts are racing against time to save what’s left. Visit soon before this island ghost town completely ghosts us all!
4. Poveglia Island, Italy
If you made a dating profile for Poveglia, you’d swipe left so hard you’d break your phone. Located in Venice’s lagoon, this island served as a dumping ground for plague victims before upgrading to a mental asylum where a mad doctor allegedly performed cruel experiments. Then he supposedly threw himself from the bell tower after claiming spirits drove him insane. Yikes.
The overgrown ruins remain strictly off-limits to visitors – not that this stops thrill-seekers from sneaking over. With plague pits supposedly making up half the island’s soil composition, it’s the ultimate “keep off the grass” situation. Venice offers plenty of less haunted attractions just minutes away. Sometimes the road less traveled is less traveled for good reason!
3. Ross Island, India
Nature’s ultimate comeback story sits in India’s Andaman archipelago. Once the “Paris of the East” with fancy British colonial buildings, Ross Island got a one-two punch from Japanese occupation during WWII and a knockout earthquake before being permanently abandoned.
Today, it looks like Mother Nature watched Tomb Raider and said “hold my drink.” Massive banyan tree roots wrap through and around buildings in the world’s coolest game of botanical Jenga. The Indian Navy now maintains wooden walkways for tourists who want to see what happens when humans check out and plants check in. Spoiler alert: the plants are winning.
2. Spinalonga Island, Greece
Just off Crete sits an island that’s basically been every kind of real estate – Venetian fortress, Ottoman settlement, and finally, in 1903, one of Europe’s last leper colonies. For fifty years, those diagnosed with leprosy were shipped here and told to create their own society. Talk about extreme social distancing!
Surprisingly, they built a pretty functional community with shops, churches, and even a hospital. When effective treatments arrived in 1957, everyone gradually left, with the last resident departing in 1962. Unlike other abandoned places, Spinalonga tells a surprisingly uplifting story of resilience. Today, boat trips bring visitors to explore streets where outcasts created meaningful lives despite everything. It’s like an inspirational poster, but with better views.
1. Hashima Island, Japan
Rising from the waves like a concrete battleship (its nickname is literally “Battleship Island”), Hashima is urban abandonment on steroids. This former coal mining facility packed over 5,000 people into a space smaller than a football stadium, creating the most densely populated spot on Earth. Think maximum-security prison meets industrial complex meets architectural nightmare.
When Japan switched from coal to oil in 1974, everyone left within weeks, leaving behind a fully-stocked zombie apocalypse movie set. Made famous in the James Bond film “Skyfall” as the villain’s lair (typecasting much?), this UNESCO site now offers limited tours to safe areas. The rest remains too dangerous to explore – though that perfect concrete dystopia skyline makes for one incredible photo op from the boat!
