Great Barrier Reef

Great Barrier Reef

The Great Barrier Reef, off the coast of Queensland in northeastern Australia, is the largest living thing on Earth and is visible from outer space. Listed as a UNESCO World Heritage site and one of the seven wonders of the natural world, it is comprised of 3,000 coral reefs and 600 continental islands stretching 1,616 miles. The reef is filled with over 600 types of soft and hard coral and is home to 100 species of jellyfish, 3,000 varieties of mollusks, 1,625 types of fish, 133 varieties of sharks and rays, and over 30 species of whales and dolphins. Snorkel through shallow waters or dive into the deep and see vibrant marine life up close. At world-famous Cod Hole, enjoy an unforgettable dive and come face-to-face with massive potato cod, which often swim right up to inspect divers with child-like curiosity.
