World's most dangerous tourist attractions

lha da Queimada Grande (Snake Island), Brazil

Hidden somewhere off the coast of Brazil, this island is widely recognized as the most dangerous place on the planet. The reason for this is quite simple — this place is full of one of the most venomous snakes in the world, Bothrops. Researchers estimate that about five snakes per square meter live on the island. There are several stories of people succumbing to the deadly predators in no time at all. One of these stories recalls a lighthouse keeper who was attacked by the snakes and died. Snake Island’s lighthouse has been automated ever since that fatality, and the Brazilian government has prohibited any visitors from setting foot there.
