Great Barrier Reef, Australia

One of the great natural wonders of the world, the Great Barrier Reef is as big as the total combined area of the United Kingdom and Ireland, and contains more than 1,000 islands, from sandy mounts to rainforest isles. Divers, snorkellers and nature lovers can reach specific sites by air or by water taxi. Non-divers can view this underwater world from a glass-bottomed boat. The Reef ecosystem has evolved over hundreds of thousands of years to give life to almost 7,000 species of plants and animals. It is home to some endangered species like the green loggerhead turtle, and is a breeding site for humpback whales. Visitors can either cruise the islands or make a base in Cairns or one of the many seaside towns along the Queensland coast. Visitors can access the Great Barrier Reef from numerous regions in Queensland, from the southern gateway of Bundaberg, Coral Coast and Country to Gladstone, Capricorn, the Whitsundays, Mackay, Townsville and Tropical North Queensland, including Cairns.
