As one of the original Seven Natural Wonders of the World, the Great Barrier Reef holds a spot on every traveler’s bucket list. Hugging the east coast of Queensland, Australia, the Great Barrier Reef extends from Cape York in the north all the way to Bundaberg in the south – more than 1,800 miles. With roughly 2,900 coral reefs, 600 islands and 1,500-plus species of fish, the reef leaves its 2 million annual visitors enchanted.
