Didn’t think we’d get to see as much as we did given the fact we were snorkling just off the beach but OMG 4 sting rays, 3 turtles, 2 sharks, 1 moray eel and hundreds of fish, sea cucumbers and star fish a vibrant royal blue. All this made possible by the lovely crew. Also lunch was pretty good too :)

The Big Cat Green Island Tour was fantastic. We were looking for a cruise on the Great Barrier Reef, but a more intimate, day-long experience with the option to snorkel from the beach. This tour really delivered and made my day memorable. A special shout out to the Marine Biologist on the tour on Oct 23rd, Aaron ( I think). He was thoughtful, patient and knowledgeable and offered a comfortable introduction to guided snorkelling. The cruise was very well organized, emphasized safety, and the staff were very available and friendly. Highly recommended!

This was a good experience for first timers up in Cairns. The tour company staff are really friendly people and look out for you if you get like sea sick etc. It was also really nice exploring green island, going in the water etc

Had a fantastic outer reef snorkel with Aly. Learnt so much. We had an amazing time. It was a shame other tourists lacked basic manners and respect as that was the most disappointing thing about the trip, especially on the boat.

A fun day on the waters of Green Island. Warm water swimming with the turtles. Snorkel equipment available to hire. Glass bottom boat was interesting & informative. Very busy boat trip with tourists. Worth a look.

Amazing place, the tour staff was excellent and very caring, I highly recommend to stay in the most controlled area near the life guards and also recommend to listen and to follow the instructions suggested by the tour guide. The reef can be deceiving because the current can be very strong at times
