It’s nearly impossible to visit these heavily guarded places on Earth

It's hard to imagine that there are places that we're not allowed to visit, especially with today's technology.

Even without the threat of death, there are plenty of places that cannot be visited because they are cut off for various reasons. Military bases, forbidden islands, and fragile natural landmarks are a few examples of destinations that are off limits to people. Take a look at some of the Earth's most guarded locations that don't allow visitors.

Located in the Andaman archipelago under India's control, North Sentinel Island is strictly off limits to visitors of any kind. This is because the island is home to the Sentinelese, an isolated tribe that has been known to react violently to trespassers. In 2018, the tribe killed an American missionary named John Allen Chau, who attempted to make contact with them.

Besides the tribe's tendency to defend the island, government officials are concerned that outside contact could introduce dangerous diseases to the indigenous population. Except for a few research excursions, no one has made contact with the Sentinelese.

Located in the ancient city of Hierapolis, Turkey, it was once the site dedicated to the Roman god of death, Pluto. After its discovery in 1965, Pluto's Gate's dangers were proven to be more than just a myth.

Scientists measured the CO2 concentration and discovered the sun dissipates the gates. At night, the CO2 becomes heavier in the air due to lower temperatures. At dawn, the CO2 reaches 35%, which is enough to kill people and animals in a matter of minutes.

Wittenoom was once an outback mining town in Western Australia that harvested blue asbestos. Blue asbestos is extremely toxic, and soon, the substance contaminated the soil and water supply. It's estimated that 2,000 workers and residents died from asbestos exposure and related diseases. Because the site is still dangerous, the town was decommissioned, demolished, and removed from maps to discourage explorers.

The ceilings and the walls of this cave are covered with parietal wall paintings. It's believed that the age of the paintings goes back some 17,000 years. Back in 1940, the caves were discovered by Marcel Ravidat, leaving people wondering about their origins and meanings. Anthropologists believe that the paintings might symbolize past hunting success or a mystical ritual. The caves are closed to tourists to preserve the artwork, but people can visit accurate recreations that are near the original site.

Mexico's Cave of Crystals contains giant selenite crystals – some of the largest ones on Earth. However, the conditions that allow these crystals to form are deadly to humans. When the cave isn't flooded, it becomes extremely hot and humid. Most people would only survive 10 minutes in the cave's environment without proper protection, and one miner died attempting to steal crystals. For this reason, the cave is closed to the public, and only scientific researchers have been allowed to enter.

Gangkhar Puensum is known as the world's highest unclimbed mountain. In Bhutan, mountains are seen as spiritual symbols and climbing them is considered disrespectful. While smaller mountaineering excursions were allowed for a time, a complete ban took effect in 2003. This was also implemented for practical reasons, as Bhutan lacks any sort of search-and-rescue infrastructure, so no one would be able to help climbers in peril.
