I know we took a boat out to the reef and must have done some snorkeling, judging by the pictures I have from the day (one of them to follow).

Agincourt Reef, off Port Douglas on the Great Barrier Reef, is a series of many smaller reefs with at least 16 different dive sites. The Channels offer interesting swim-throughs and caves, while The Gardens are renowned for their exceptional abundance of brightly colored reef fish. Blue Wonder is a breathtaking wall dive to beyond 40 meters, while Nursery Bommie is a spectacular pinnacle where pelagic fish gather to feed. (Queensland.com)
