Set sail from Cairns aboard Ocean Spirit, a beautiful 32 metre sailing catamaran, to the unique and pristine reef environment of Michaelmas Cay. Encircled by fringing reef teeming with colourful marine life including sea turtles and giant clams, it is also a protected seabird sanctuary. Access to the cay is restricted to preserve this special environment. Snorkel directly from the beach in the cay's protected shallow waters, cruise in the semi-submersible for a diver's view of the reef, watch the fish feeding presentation and observe the fascinating island bird life. The "beach buggy" will shuttle you between the boat and cay throughout the day. For the more adventurous, you can experience the underwater delights of the reef with an exciting introductory scuba dive. Guided snorkel tours are also available. Or if you prefer just relax on the beach or on board and enjoy a leisurely day on the Great Barrier Reef.
