Great Barrier Reef

Sometimes called the necklace that adorns the northeastern Australian coast, the Great Barrier Reef is the largest in the world. It is a collection of more than 3,000 distinct reefs and island fleets, protected by the turquoise waters of the majestic Coral Sea. Together, the Great Barrier Reef was proclaimed a UNESCO World Heritage Site in 1981. Waters run shallow for a large portion of the reef, making the perfect environment for aquatic adventures before the reef dips to a depth of 2,000 meters (6,561 feet). Diving and snorkeling here are like being transported to a different world, where swirling, rainbow-colored corals create a colorful backdrop for so many fish species. You'll never forget the mesmerizing waters of the Great Barrier Reef.
