While we may wish we could travel anywhere in the world, the reality is that there are some places that due to political or natural barriers, most of us will never have the opportunity to actually visit. While we might not be able to visit these elusive and exclusive locations, here are a few places we can still marvel at from afar.

Snake Island, Brazil

Ilha da Queimada Grande, or Snake Island, as it’s more commonly known, is a stunning 43-hectare island located off the Brazilian coastline. While it may look beautiful in photos, this remote South American island is home to one of the world’s most deadly species of snake, the Golden Lancehead Viper, whose venom can eat through flesh. In fact, scientists have tracked more than 4,000 of these deadly reptiles on the island, but local lore states that there is one snake for every five square meters of land on the island. It’s so dangerous to step foot on Snake Island that the Brazilian government has prohibited visitors on the island, with the exception of a few scientists who have received permission to go for research purposes.JMR_IQG_004.JPG

Lascaux Caves, France

This intricate series of caves in Northern France is home to one of the best examples of Paleolithic cave paintings ever discovered. This 17,000 year-old ancient artwork depicts mostly extinct ancient animals that have been proven through fossils to have existed during that time. The United Nations have even listed it as an UNESCO World Heritage Site. However, since 2008, the caves have been closed off to the public due to a fungal outbreak, with only a select number of scientists allowed entrance a couple of days per month to study these stone-age paintings.Lascaux Caves, France
