Ningaloo is the home of giants. These nutrient-rich, radiant blue waters off the coast of Western Australia play host to the world's largest fish — whale sharks — who return each year to gorge on plankton (and swim with humans). Pods of orcas here stalk humpback whales as they pass. Black marlin cruise the currents. Tiger sharks roam the deep. And that’s just the tip of the coral. Last June, the World Heritage Committee inscribed Australia’s Ningaloo Coast as an official World Heritage Site and it’s absolutely deserving of a spot on your bucket list.
