12. Snake Island
About 90 miles from the city of São Paulo lies Ilha de Queimada Grande, or “Snake Island” – a place so filled with venomous serpents that it’s been called one of the world’s deadliest islands. Scientists estimate that up to 4,000 snakes live on the 110-acre island – that’s one snake for every six square yards. Queimada Grande is the only known home of the golden lancehead, one of the most venomous vipers in the world. The snake’s venom is said to be three to five times stronger than that of any mainland snake.
