The Great Barrier Reef is one of the most colorful places on Earth. It is Australia’s natural wonder, larger than the Great Wall of China and the only living thing on earth visible from space. Heron Island offers easy access to the Great Barrier – just get in the water and you’ll be among ridges overrun with 900 different species of sea life, including parrotfish, giant turtles, surgeonfish, sea cucumber and starfish.
