Australia’s Great Barrier Reef is the world’s largest coral reef system. It stretches over 1,250 miles along the eastern coast of Australia.
Often called the Eighth Wonder of the World, the Great Barrier Reef is the world’s largest structure made up of living organisms. Many visitors to this favorite vacation spot wriggle into swim togs and snap on snorkels. The most daring visitors strap on air tanks. They dive 20 feet below the surface for an up-close look at castles of coral and even a few not-so-friendly sharks. For the less adventurous, glass-bottom boats offer tours of this underwater world.
