Located in the Atlantic Ocean off the coast of Brazil, “Snake Island” (Ilha da Queimada Grande) is not a place you would want to visit. Visitors are not permitted, as this hazardous island is home to the world’s deadliest, most endangered snakes.

There are around 15,000 species of snakes that call the Island home, and the 106-acre is crawling with millions of the reptiles. Going to Snake Island illegally is a surefire way to get a nasty, likely fatal bite. Should you survive, you’ll incur a fine from Brazil for trespassing, if not a prison sentence.
