The 2,300-kilometer Great Barrier Reef is the largest coral reef system in the world. This living wonder offers fantastic opportunities for swimming, snorkeling, diving and sailing. Despite its name, the Great Barrier Reef is not a continuous reef formation, but consists of almost 3000 individual reefs. These reach from the northeast of Australia to Papua New Guinea. The Great Barrier Reef is one of those places you must visit, whether you love the water or just want to see one of the great wonders of the world.
