Con­sid­ered as one of the dead­liest places, Snake Island in Brazil is def­i­nite­ly one of the most dan­ger­ous places on Earth. 90 miles from the city of Sao Paulo, this super dead­ly island is home to the largest con­cen­trat­ed pop­u­la­tion of snakes in the world. Accord­ing to research, Snake Island aka Ilha da Queima­da Grande has about five snakes per square meter. It is said that snakes on this Brazil­ian island are so ven­omous that they can melt human flesh. This island is the only place in the world where the gold­en lance­head viper is found and the most ven­omous snake in the world, the Both­rops thrives. Due to the extreme­ly high risk for tourists and black mar­ket demand for lance­head ven­om, the Brazil­ian gov­ern­ment has strict­ly pro­hib­it­ed vis­its to Ilha da Queima­da Grande.
