Enjoyable day out

4.00We enjoyed our trip to Green Island. Everything was well organised, and wasn't sure what to expect, but ut we had a good day. Didn't realise we were being charged in US dollars which made it a bit more expensive than we thought.
A must do if you are planning a trip to Cairns!

5.00A great family day out with lots to see and do, a little on the expensive side but well worth the experience. As a family of three we took the full day option and in that time we managed a glass bottom boat tour, snorkelling, visiting the crocodiles, a bush walk and a play in the pool as well as a quick bite to eat
Good experience

5.00Well done trip. Some of the activities are not available at Green Island that are available at the leaf Island. Can easily spend the whole day at Green Island and if possible try to do the longer duration trip.

5.00Severe weather conditions meant we couldn't do much on the island once we arrived unfortunately BUT they refunded all our money back without question when we returned via our agent which was handled very well
Great experience.

5.00The ferry crews were so friendly and caring. We enjoyed the glass boat tour and the snorkeling activity. This was also the cheapest, we stayed from 8:30 - 4:30, it was worth the visit.

Green Island Tour with Guided Snorkeling Great Experience
Teresa D,,Oct 26, 2025

5.00Excellent tour for limited time in Cairns very organized . Recommend paying for guided snorkeling out in the sea with marine biologists to see and learn so much more. Cara our guide was excellent conscientious and gave great information. She loves what she does and it showed! Good ROI for extra expense. Also we are glad we bought the underwater picture package not cheap but the professional pictures so much clearer than our rented underwater camera. It was great to be at Green Island with excellent facilities.
Great day on Green Island
