Great Barrier Reef

This is something truly amazing. Great Barrier Reef is the world’s largest coral reef system, consisting of close to 3,000 reefs and 900 islands stretching for over 2,600 kilometers over an area of approximately 344,400 square kilometers and is located in the Coral Sea, off the coast of Queensland in north-east Australia. The Great Barrier Reef can be seen from outer space and is the world’s biggest single structure made by living organisms and is labeled as one of the seven natural wonders of the world. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps.

The place really has a treasure as it contains over 1600 species of fish, more than 3000 kinds of shells, over 600 species of starfish and sea urchins, 14 types of sea snakes, 215 species of birds (22 of which are seabirds), 30 different types of dolphins/whales and over 100 types of sharks/rays. A variety of boat tours and cruises are offered, from one day trips, to longer voyages. Boat sizes range from dinghies to yachts. Glass-bottomed boats and underwater observatories are also popular, as well as helicopter flights. By far, the most popular tourist activities on the Great Barrier Reef are snorkeling and diving, for which pontoons are often used, and the area is often enclosed by nets. The outer part of the Great Barrier Reef is favored for such activities, due to water quality.
