Visiting Brazil’s Ilha da Queimada

Visiting Brazil’s Ilha da Queimada Grande is forbidden. That’s because the island, located 33km off the state of Sao Paulo, is swarming with venomous snakes. Snake Island, as it’s called, is home to an estimated 4,000 venomous Bothrops insularis, also known as golden lanceheads, a critically endangered species that got trapped on the island when rising sea levels covered up the land that connected it to the mainland.
The snake’s venom can cause kidney failure, brain hemorrhaging and many other alarming ailments
