Though Area 51 has been the subject of a Netflix movie of the same name, it’s anybody’s guess as to what happens there. Fines and penalties for sneaking into the alien-and-UFO site are steep, reaching well over $2,000 per violator.

These scholars can access three pre-requested documents per day, no more. Technically, the owner of this secretive library is the Pope, as he owns it until he either dies or resigns. Then, ownership transfers to his successor.

Little Hall’s Pond Cay is a privately-owned island that is off-limits to the public, though the public will likely know its former owner. Johnny Depp, the star of the Pirates of the Caribbean franchise, bought the island years ago before later re-selling it to J.K. Rowling.

Little Hall’s Pond Cay certainly looks like something out of a Disney movie, as it is full of lush, tropical vegetation, clear waters, and white sands. The buildings on the island are solar-powered, and the surrounding lands are all part of a wildlife refuge.

Maya Bay’s ecosystem became heavily damaged because of boat traffic, with congestion and pollution killing off 80% of its coral reefs. As a result, Maya Bay was shut down. Now, if the public wants to see it, they can rent The Beach on Amazon Prime Video.

Because of its location, no one is allowed to attempt to visit Tillamook Rock Lighthouse. Nicknamed “Terrible Tilly” for its harsh location, the Lighthouse is rumored to be cursed by gods, spirits, and/or ghosts.

There are around 15,000 species of snakes that call the Island home, and the 106-acre is crawling with millions of the reptiles. Going to Snake Island illegally is a surefire way to get a nasty, likely fatal bite. Should you survive, you’ll incur a fine from Brazil for trespassing, if not a prison sentence.

Though visitors can see Bhangarh in all its former glory during the day, its haunted reputation means that it is off-limits to visitors after sunset and before sunrise. Those found at Bhangarh after dark risk jail time and fines…if not a curse or two from the priest’s ghost that haunts the ruins.

Only nesting herons use the island, which was valued at $1.1 million in 1970 ($8.62 million in today’s money). That’s probably for the best, as the ruins of the island are covered in thickets of poison ivy and other hazardous, rash-causing flora.

The Dulce Base story has been bandied about by conspiracy theorists for a while. According to Michael Barkun, a political scientist, there are Cold War underground missile installations throughout the New Mexico territory, so a military base belowground could plausibly exist.

That said, the conspiracy theories, which include claims about aliens, firefights between extraterrestrials, abductions, and more, are a bit less believable. Regardless, underground missile installations are off-limits to the public, and one that handles aliens and alien conflicts would definitely be a no-go zone.

Unfortunately, this site is under threat due to illegal gold mining activities, which cause conflicts in areas where state conservation units overlap with Yanomami territory. The Yanomami, by nature, are fishers, hunters, and horticulturists—they have no use for gold mining, viewing it as a threat (which it is, to them).

These intruders are punished just as harshly as defectors, as North Korea punishes those who travel without a valid visa. Detention and arrest usually follow, as does a lengthy prison sentence and, according to some prisoners, torture. Many countries have imposed travel bans on citizens who want to go to North Korea, both to protect themselves and to avoid war with the capricious, mysterious Kim Jong Un.
