Diving in the Great Barrier Reef (Great Barrier Reef), is an experience you will not forget. It is the largest coral reef in the world (about 2000 kilometers), and a true wonder of nature, and was declared a World Heritage Site in 1981. Located on the coast of Australia, specifically in the state of Queensland, the country's northwest. I dove a couple of times in Cairns, one of the most important cities in northern Australia, and it is one of the favorite destinations for scuba divers or fans of snorkelling. They can get your divers license (PADI) or, if you already have it you can hire an excursion dives.
