Earth is more connected than ever, but there are still “black spots” on the map where you can never go. These are the forbidden places—islands, caves, and vaults that are strictly off-limits to the general public. Some are guarded by the military, while others are protected by nature itself. If you try to set foot in these locations, you could face arrest, or worse, you might never come back. These spots hold secrets that the world isn’t ready to see. From deadly animals to ancient diseases, the reasons for these bans are often terrifying.
While you can see them on Google Earth, you can never experience them in person. They are the last true mysteries of our planet. Governments and international laws keep these sites locked away to protect either us or the environment. But some of these bans aren’t for our safety—they’re meant to protect a way of life that has remained the same for 30,000 years. Let’s start with the most dangerous island in the Indian Ocean.
The island that will kill you on sight
North Sentinel Island is home to the Sentinelese people, one of the last “uncontacted” tribes on Earth. They have lived there in total isolation for tens of thousands of years. They are extremely hostile to outsiders and will fire arrows at anyone who approaches. The Indian government has banned all travel within five miles of the island to protect the tribe from our diseases and to keep travelers from being killed. It is a place where time has literally stopped. But wait until you see the island that is reserved for the birds.
A volcanic birth that is strictly off limits
Surtsey Island in Iceland didn’t even exist before 1963. It was created by a massive underwater volcanic eruption. Now, it is used as a giant laboratory to see how life starts on a new island without human interference. Only a few select scientists are allowed to visit, and they must follow strict rules—no seeds or bacteria may be brought in. One scientist was famously kicked out for accidentally growing a tomato plant from a discarded snack. But the next island on our list is full of literal monsters.
The island where snakes rule the world
Ilha da Queimada Grande, also known as Snake Island, is located off the coast of Brazil. It is home to thousands of Golden Lancehead vipers, one of the world’s deadliest snakes. Their venom is so strong it can melt human flesh. There is roughly one snake for every square meter of land. The Brazilian Navy has banned all civilians from the island for their own safety. It is a place where you are never more than three feet away from a painful death. But some forbidden places are hidden under the ground.
The vault was built for the end of the world
Deep inside a mountain on a remote island in the Arctic sits the Svalbard Global Seed Vault. It is designed to survive a nuclear war or a global catastrophe. It holds millions of seeds from every country on Earth, acting as a “backup drive” for our food supply. The vault is built to last 1,000 years and is strictly off-limits to everyone except the scientists who run it. It is the ultimate insurance policy for humanity. But some underground places are banned to save the past.
Art that is too fragile for human breath
The Lascaux Caves in France contain some of the most beautiful prehistoric art ever found. For years, tourists flocked to see the 17,000-year-old paintings. But the carbon dioxide from human breath started to grow mold on the walls, destroying the art. The caves were permanently closed to the public in 1963. Today, a perfect replica exists nearby, but the real cave remains a silent, dark tomb for the past. But what if the forbidden place is guarded by the military?
The most famous secret in the desert
Area 51 is a US Air Force facility in Nevada that officially doesn’t exist on most maps. While the government says it’s just a testing ground for experimental aircraft, the high security and secret hangars have led to decades of UFO rumors. If you try to cross the border, you will be met by armed guards and high-tech surveillance. It is the most heavily guarded piece of dirt on the planet. But you won’t believe the “haunted” island that Italy had to close down.
The island of the plague ghosts
Poveglia Island in Italy has a dark history. It was used as a quarantine station for the bubonic plague and later as a mental asylum. It is rumored that 160,000 people died there, and their ashes make up 50% of the island’s soil. The Italian government has banned all tourism and travel to the island due to its dangerous ruins and dark reputation. It is widely considered the most haunted place on Earth. But wait until you see the drink you should stop having in the morning.
