For 25 years, the remote Colombian island of Gorgona was a prison, housing the nation's most notorious criminals. Surrounded by dangerous reefs and shark-infested waters and crawling with venomous snakes, escape was impossible for its 2,500 inmates. Now, nearly 40 years after the prison was abandoned, the deadly threats still exist, but are protected as part of a national park. Explore the spectacular wildlife that now run the prison, jungles, and seas of Gorgona, and witness how futile escape must have been for a prisoner on the run.
