Diving and Flying Over the Great Barrier Reef

One of the experiences I was most looking forward to in Australia was diving in the Great Barrier Reef. As I wouldn't be spending too many days in Cairns, and would be both flying in and out of the city, I was unable to actually dive with an oxygen tank, but chose to snorkel instead. I signed up for the Cruise and Fly Reef Tour through Expedia, and it was an incredible experience.
