Devils Island, French Guiana
Before they were a notorious penal colony, the Iles de Salut (Islands of Salvation) provided French colonists with a welcome escape from the fever-ridden jungles of the Guiana mainland. Lying ten miles off the coastline, and swept by treacherous ocean currents, the trio of small islands provided a perfect isolated location for incarcerating criminals without danger or expense, since the shark-infested sea and the trackless jungles ashore precluded any possibility of escape. All three islands, popularly known as Devil's Island, were used as a prison from 1852 to 1953. Your day is free to explore the prison ruins or search for signs of the surprisingly abundant wildlife.
