Do we really need to explain why visiting this island is a colossally bad idea? Known as Ilha da Queimada Grande in Portuguese, Snake Island is located off the coast of Brazil in the Atlantic Ocean. The place is teeming with one of the most venomous snakes in the world - the Bothrops viper. And we have to say, we're very relived they've all just decided to live isolated on this little island together.
If it were possible, we're certain some adventurers would be taking the next boat out. But thankfully for everyone, including the snakes, the island is closed to the public. Due to their isolation and lack of predators, the species has multiplied at a rapid pace, to the point where the island is 100% uninhabitable for humans. The only people allowed out there are the Brazilian Navy.
