Climb aboard a modern, air-conditioned catamaran to cruise over to this idyllic part of the Great Barrier Reef. Enjoy a full-day reef tour, just a few minutes away from Cairns. Snorkel and dive among the reef fish and coral gardens or laze on the white sandy beach and soak up the sun.

Great day out. Trip in sub and glass bottom boat only 20 mins each, would have been nice if they were longer. I took option to have lunch also provided but not overly impressed with what was offered as not to my taste. Would have been better taking my own lunch with me.

Everything ran smoothly transportation was on time and comfortable,maybe some more information re diving locations when we reached the island would help immensely.The food was pretty basic but it was a wonderful location and experience that could be enhanced more by improving the above.

Me, my husband, and my friend had such an amazing adventure together snorkeling. We had been looking forward to it for ages and it did not disappoint! We did have the buffet lunch add on too. The food was fine and I loved it was in aircon . I do think though that the buffet lunch isn't necessary and would pack my own next time. It didn't 'wow' me enough to recommend.
