The Great Barrier Reef, by the way, is awesome. One of a short list of wonders of the world that I’ve seen, along with Milford Sound, Yosemite Valley, and the Grand Canyon.
The Daintree Rainforest is pretty amazing, also. There’s not many places where you can stand on a beautiful beach, with the world’s oldest rainforest on one side, beautiful mist-covered hills looming above you, and with coral reef on your other side.
All in all, a very good trip.
