With new transportation links and travel apps that improve planning and booking, the most secluded corners on earth have become closer than ever. However, there are some places around the world that will never make it into the tourism brochures, and for good reason. Whether it's because they are considered spooky and haunted or are simply naturally unsuitable for human beings, the destinations on this list below are closed off from the public. Here's are some of those places...

This one isn't just a very old library but is one of the largest and most secretive libraries on the planet. In fact, only a sacred few have access to the wonders the vaults offer. From ancient Maya codices to ancient books that ‘allegedly’ are proof of alien contact, the Vatican Secret Archive is said to have it all!

This one is really strange. It is a restricted 2,700-acre campground located at 20601 Bohemian Avenue, in California. The land is believed to be owned by a private San Francisco-based arts club called the Bohemian Club.It turns out that every summer, the Bohemian Club hosts a two-week camp in the woods where the most influential people in the world gather and if you aren't one of them, this place is strictly off limits for you.

This place is considered 'cool', both figuratively and literally. The Seed Vault is just 800 miles away from the North Pole. The Seed Vault houses every type of seed this planet has to offer. This has been done to revive species of plants just in case a disaster of a massive scale wipes out botanic diversity from earth. The vault performs like any regular bank in the sense that governments can send seeds to be stored in this vault.

The reason why this beautiful place has been completely abandoned is because it is considered to be one of the most haunted places on earth. The island has a fort and has been a checkpoint for ships and has also been an isolation home to plague patients and had a psychiatric facility until 1968. The departed souls of those plague patients and mentally deranged individuals are still rumoured to be roaming around the island.

This place has been given the privilege of being a World Heritage Site by the UNESCO. However, it has been inaccessible to the public since 2008. The caves hold intricate and beautiful paintings of animals drawn in ancient times. An unfortunate fungal outbreak inside the caves compelled the French government to close the caves off permanently. Only historians interested in conducting academic research are allowed here.

This island is a small one and covered in greenery, however, it is very inaccessible because the coral reefs around it make it difficult to reach on water vehicles. Helicopters may have been able to access the remote island, but the obstacle, in this case, is not the environment of the island, but its inhabitants, the Sentinelese. They are hostile to others and don't like to plays hosts to guests either. They have been known to shoot at helicopters with arrows.

This 43-hectare island harbours one of the deadliest species of snakes in the world. The snake population is around 4,000 and chances are that you will not be able to find your way on the island unless you’re a biologist. The Brazilian government only allows a limited number of biologists and researchers to visit the island once in a few years to study the snakes.

This place is the deadly combination of icy glaciers and active volcanoes. One of the volcanoes on the island – the Mawson Peak started spewing lava from its 2,745-foot high crater in the year 2000. This island is home to animals such as marine birds, seals and penguins.
Don't these places make you want to jet-set off right away?
