The Great Barrier Reef, Australia
Ranked as a #1 world destination by U.S. News and World Report, the Great Barrier Reef extends 1,250 miles of Australia’s east coast. The area features 1,625 different species of fish, which makes it a top spot for divers and aquatic adventurers. Over recent years, the Great Barrier Reef has teetered toward being placed on the endangered list, so tread carefully and responsibly. The area has more to do than just diving, however — don’t miss the chance to see the Reef from above with an air tour.
