Thanks to the Internet and low-cost companies, the world is much less unknown than a couple of decades ago. However, not all corners of the planet are within our reach.
Whether it's an island infested with poisonous snakes or the pope's secret files, you'd better not be too fond of these destinations since they're only within the reach of a select few.

Here we show you 10 fascinating places that unfortunately you will not be able to visit in life:


1- Area 51 - Nevada

Area 51 is probably one of the most secret places on earth. Also known as Groom Lake , the purpose of the base of the United States Air Force remains unknown to the rest of humanity, which of course leads to speculation and hundreds of conspiracy theories.
The use as a place of development of super secret weapons has been the most widespread theory among the society since the base was established by the Central Intelligence Agency (CIA). However, there are those who think that this is where the US government hides all the remains they find of extraterrestrial life on earth .
Although Area 51 has never been declared a secret base, it was not until 2005 that the government of the United States publicly acknowledged its existence . Access to the area is controlled by motion sensors, is totally prohibited for civilians and airspace is not available for commercial aircraft.

2- Club 33 - Anaheim (California)

In 1967 the Club 33 opened, a place designed by Walt Disney , exclusive for the most fortunate and that remains one of the most secret, mysterious and above all demanding clubs for those who want to be part of it. Among its members we can find artists, presidents and billionaires.
Located at the intersection of Royal Street and Orleans Street in the New Orleans Plaza, Club 33 was intended as a place to receive dignitaries, investors and only the most exclusive celebrities. 
The waiting list for membership is several years and only after entering an initiation fee (which is rumored between $ 25,000 and $ 100,000), members pay an annual fee of $ 12,000 .
In return, members have access to two dining rooms, VIP cards, valet parking, access to the jazz room "Le Salon Nouveau" and to Room 1901 at Disney California Adventure, the only place where alcohol is served at Disneyland.

3 - Cave of Lascaux - Lascaux (France)

The famous Lascaux cave is found in all history books because it is the largest prehistoric art museum on earth .
In the more than 600 works of art that adorn the complex of caves located in the southwest of France you can see horses, deer and plants corresponding to Upper Palaeolithic fossil records .
Despite having been declared a World Heritage Site by UNESCO in 1979, the caves have not been accessible since 1963 . After opening them to the public after the Second World War, the presence of visitors and the constant light gave rise to different problems such as the growth of lichens and fungi , forcing their permanent closure for better conservation.

4 - North Sentinel Island - Andaman Islands (India)

The island of North Sentinel, in the Bay of Bengal southwest of the Andaman Islands, within the Indian Ocean, is one of the few redoubts completely removed from human civilization . A fascinating place populated by natives so aggressive and hostile that the world has simply stopped caring.
Almost nothing is known about the indigenous tribe that has inhabited the island for more than 60,000 years as it is  isolated from modern civilization by its own choice.
After the incessant failures to establish some contact, the Indian government has stopped all attempts and prohibited travel less than three miles from the island. In 2006, two fishermen were killed when they broke the rules and visited the island.

5 - Poveglia - Veneto (Italy)

The small island of Poveglia is described by the local inhabitants as the most "enchanted" place on earth . There is a collective cemetery of plague victims and other people with infectious diseases. 
The island also housed a psychiatric hospital where it is rumored that a doctor performed experiments on patients (before committing suicide).
Very few people have set foot on the island since the 1960s. The locals themselves only take the bravest in exchange for a very high price.

6 - Tomb of Qin Shi Huang - Xian (China)

Even to this day, the tomb of the first Chinese emperor Qin Shi Huang remains a mystery.
In 1974, what is still one of the greatest archaeological finds of all time took place, a set of more than 8,000 figures of warriors and life-size terracotta horses  buried near the self-proclaimed first emperor of China of the Qin Dynasty, Qin Shi Huang, in 210-209 a. C.
The warriors have remained there for more than two millennia , and as it seems, this will continue to be the case since the tomb will not open in the near future, neither for scientists nor for tourists. It seems that no current technology is ready to deal safely with the excavation .

7 - Isla de las Serpientes - São Paulo, Brazil

What could be a beautiful tropical island is actually one of the most lethal places on earth. Ilha da Queimada Grande, also nicknamed Isla de las Serpientes, is home to thousands of highly poisonous vipers .
The island is about 90 kilometers from the coast and access is strictly controlled by the Brazilian government. Some estimates hold that in some areas there is one snake for every 30 square cm.
The annual visits of the navy to take care of the lighthouse are always carried out in the presence of a doctor, since the bites can cause internal bleeding, kidney failure and death.
Although snakes are dangerous, the real reason why the island is closed to the public is to protect the snakes from poaching.

8 - World Bank of Seeds of Svalbard - Spitsbergen (Norway)

Although it is unlikely that you will reach the small Norwegian island of Spitsbergen, some 1,300 kilometers from the North Pole , in case you do, the World Bank of Seeds will definitely be out of your reach.
Hidden inside a mountain with an earthquake-proof structure, the most precious crops in the world are stored.
Since 2008, almost all the countries of the world have filled this international warehouse with their own specimens, adding  more than 865,000 different samples , of which 150,000 are rice-only.
The installation in Spitsbergen serves as a backup for the more than 1,700 gene banks located throughout the world, ensuring the survival of the species in the face of any natural disaster or any disaster caused by man. As the seed vault in Norway acts as a copy, no access is granted to researchers, scientists or breeders.

9 - Secret Archives of the Vatican - Rome (Italy)

A visit to the secret archives of the Vatican would surely head the list of "places I have to go before I die" of any lover of history, however, I fear that it will only become an unattainable dream.
Only a very small number of scholars can lay their hands on unique documents such as the papal bull of 1493 that divided the New World between Spain and Portugal or a request of 1530 asking for the annulment of the marriage of King Henry VIII with Catherine of Aragon .

10 - White's - London (United Kingdom)

Gentleman's clubs have been an institution of British culture for centuries and none is older or more exclusive than White's in London.
Founded in 1693 , it remains an establishment for gentlemen only , although some exceptions were made for Queen Elizabeth II on two occasions. Membership is restricted to 500 men and the waiting list is several years .
