Unforgettable experience - If I could give it 500 stars, I would. The company is very responsible, meticulous, and its staff is top-notch. Everything that was stated in the brochure was done to the letter. Abundant lunch, delicious snacks. Not to mention the experience itself regarding the Great Barrier. Every dollar we paid was worth it. Highly recommended 👌

A fantastic day trip from Cairns- highly recommended for a safe snorkeling experience with lots to see - This was a very well organised day trip from Cairns. It is a very professionally organised tour, with safety of the participants a priority We had time on Green Island to walk around the edge, snorkeling twice off the beach and saw lots of fish then a coffee before reboarding for our trip out to the reef. While waiting for the boat we saw 2 turtles and got some great pics The reef pontoon was so great. Easy access to the water to snorkel, under water viewing and an underwater submarine type boat that had incredible views. Lunch was nice and small snacks are also given. My husband and I were really impressed with the whole day

Forget Green Island - Mixed feelings about this trip. Green Island is a total waste of time. Went snorkelling and lucky if I saw 4 fish. Also eaten alive by mozies and bugs. The outer Barrier Reef on the other hand was fantastic. Exactly what I expected and why I went. So if booking a trip just do the second part (the outer reef) and forget Green Island. In Sydney now and still nursing my bites.
