The islands of Oceania are among the most idyllic on Earth. Separated by vast expanses of ocean, the subregions of Micronesia, Melanesia and Polynesia include a broad range of environments from the massive mountains of Papua New Guinea to deserted atolls and lagoons of fantasy. Located in a geographic area that extends over three million square miles, they support an incredible diversity of tribal cultures with an intriguing repository of ancestral traditions, and enough untouched natural beauty to last a lifetime.
