There are countless hidden corners of the world—but some are so off-limits, you’re not even allowed to go near them. These are the forbidden places you can’t visit, no matter how curious or adventurous you are. From secret islands and radioactive ruins to sacred tombs and government black sites, these locations are completely closed to the public—and the reasons why are as bizarre as the places themselves.
Whether it’s for safety, secrecy, or straight-up strangeness, these destinations have been sealed off from the world. In this article, we’re exploring some of the most fascinating places you’ll probably never set foot in—and the wild stories behind their locked gates.
🏝️ North Sentinel Island – The Island That Wants to Be Left Alone
This tiny speck in the Indian Ocean is home to the Sentinelese, an isolated tribe that has violently resisted contact with the outside world for centuries. Attempts to approach the island have been met with arrows, spears, and absolute hostility.
It’s illegal to get within 5 nautical miles of the island. Why?
- To protect the tribe, who have no immunity to modern diseases.
- To protect outsiders—they’ve made it clear they want to be left alone.
In 2018, an American missionary tried to visit the island illegally. He was tragically killed within hours. Lesson learned: they mean it when they say “no visitors.”
