It's interesting that there are some locations in the globe that are entirely off-limits to visitors for one reason or another, unless you're a scholar or a daredevil ready to risk your health and, occasionally, your life.
Here are some places in the world where visitors are not allowed;
1. Snake Island, Brazil
Ilha de Queimada Granda, sometimes referred to as Snake Island, is home to tens of thousands of the world's deadliest snakes. Some estimates place the number of snakes on the island at one per square meter. There are also said to be about 4000 golden lanceheads on the island. Public access to Snake Island is prohibited for obvious reasons.
2. Lascaux cave, France
The cave complex that makes up this UNESCO World Heritage Site is home to some of the most well-known Paleolithic cave drawings that have ever been found. The paintings, which date to around 17000 years ago, mostly show pictures of enormous creatures that have been identified via fossil excavation as being in the region at that time.
In 1963, the public was fully barred from the caverns because the presence of tourists and the flood of light led to a number of issues, including the growth of lichen, bacteria, and fungi.
3. Svalbard Global Seed Vault, Norway
This worldwide seed vault, often known as the Doomsday vault, has around 100 million seeds from all over the world in case something awful occurs to the planet's flora.
It was inaugurated in 2008 with a 200-year lifespan in mind. Both earthquakes and bombs won't damage it. It was positioned on a mountainside so that it would remain above sea level even if all the ice on Earth melted.
4. North Sentinel Island, India
The Sentinelese tribe of India, an indigenous people living in intentional seclusion, is located on the North Sentinel Island. They have vehemently shunned all interaction with the outside world. About this tribe, which has lived on the Island for more than 60 thousand years, not much is known.
In fact, the Sentinelese would attempt to murder you if you stepped foot on the Island. In 2006, two illegally fishing fisherman perished after their boat wandered too near to the island.
The Indian government forbade travel within three miles of the Island after several failed attempts to contact this group. One of the world's most hazardous and banned locations is North Sentinel Island.
 5. Poveglia, Italy
Locals claim that this little island off the coast of Venice is the world's most haunted location. Poveglia served as a quarantine location for persons suffering from the bubonic plague in the 1700s. In 1922, the Island buildings were eventually transformed into a facility for people with mental illnesses.
Since 1968, when the mental institution was shut down, it has been unoccupied. There are rumors that the ghosts of disease, war, and asylum doctor who murdered patients walk the abandoned premises.
