The tip of a submerged volcano, framed by postcard-perfect castaway beaches and virgin Atlantic rainforest cascading over its dramatic clifftops, Fernando de Noronha might just be the last pristine island on earth, untouched by mass tourism.

The colour saturation dial is on full here. A national marine park and UNESCO world heritage site, its crystal-clear water (visibility up to 50m and year-round water temperature of 26°C) is the most dazzling turquoise, its rocks a rich gunmetal and its jungle the colour of emeralds. With exciting dives at all levels, you can snorkel and scuba with a Crayola box of tropical fish, spotted rays, turtles, dolphins and reef sharks.
