6 Forbidden Islands On Earth No One Is Allowed To Visit (2 of 4)

2. Ilha de Queimada Grande, Brazil
Brazil says it closed Snake Island to protect the critically endangered golden lancehead viper, but let’s be realno one’s buying that. Officially, the island swarms with venomous snakes, and these golden lanceheads are so deadly that even with an antidote, you might still bleed from your eyes, go into kidney failure, or die from brain hemorrhaging. This sounds like nature’s version of a bioweapon.
But here’s where it gets shady. Why are they only on this one tiny island? Why are they so numerous? Some speculate that the government may have been conducting experiments on bioweapons or snake venom pharmacology, and then sealed the island once things got out of hand. There are even tales of illegal research facilities deep in the jungle, now “abandoned” but still off-limits. And since no civilians are allowed, we’re stuck with secondhnd reports from researchers under tight restrictions.
Perhaps it’s an attempt to preserve the environment or a clever way to conceal a location that never existed. You’d think that with modern drone tech, someone would have leaked footage by now unless they have a counter for that, too.

3. North Sentinel Island, India
North Sentinel Island is off-limits for a reason, but is it truly about safeguarding the tribe? Officially, the Indian government says it’s shielding the uncontacted Sentinelese people from modern diseases. And yeah, they’ve been known to fire arrows at anyone who dares approach. But why has every attempt at peaceful contact failed so violently time after time?
North Sentinel has essentially acted as a real-life Area 51 since its discovery in 1771. In the 1800s, the tribe attacked a British crew. In 1974, the tribe shot arrows at a National Geographic team, causing them to bury all their “peace offerings” on the beach. American missionary John Allen Chau attempted to convert the tribe in 2018, but the tribe promptly killed him and left his body on the sand as a warning.
Some conspiracy theorists believe the island is a living human experiment: an isolated group either intentionally kept in the past or hiding something ancient and powerful. Others point to unexplained military flyovers and the eerie precision of the Sentinelese archers as proof they’re more advanced than they look. Whatever the case, no one’s getting within 9 kilometers of that piece of land. And that kind of security raises more questions than it answers.
