20 Most Mysterious Places on Earth You Cannot Visit

If you have the money, the flights, and the gear, you are still not getting in. The reasons fall into four categories: distance, where the cost of reaching a place exceeds any possible reward; environment, where the air or heat kills you before help arrives; law and firepower, where a signature and soldiers close the door; and voluntary secrecy, where the people inside lock the door themselves. By the end, a pattern emerges: some of these doors are not keeping us safe from the place. They are keeping the place safe from us.

The Loneliest Places on Earth

The first lock is distance, and it is the most effective because the planet maintains it for free. Bouvet Island, a Norwegian territory in the South Atlantic, is the loneliest island on Earth—a measurable fact, not a slogan. It is 49 square kilometers of volcano, 93 percent buried under ice. The nearest land is Antarctica, 1,700 kilometers south; the nearest inhabited place is Tristan da Cunha, over 2,200 kilometers away. There is no airstrip, no harbor, and the Southern Ocean at 54 degrees south does not calm down. Landings are done by helicopter in a weather window that might last two hours. In 1964, a British expedition found an abandoned boat on a new rock terrace—intact, with oars stowed, no identification, no bodies. By the time anyone returned, the sea had taken it. Nobody ever reported a missing boat.
