Reviews: Cairns Green Island Big Cat half-day tour with snorkeling/glass-bottom boat
Guest User2026-01-31
Since we only had a short stay, we decided to take a quick afternoon tour. The boat ride to the island was very rocky due to the rain and rough weather. I got seasick and couldn't move, so I recommend taking motion sickness medicine if you are prone to seasickness. I was impressed to see sea turtles swimming gracefully nearby.

Reviews: Cairns Big Cat Green Island Great Barrier Reef Cruise Half-Day Tour - Optional Morning/Afternoon Snorkeling & Glass Bottom Boat
Guest User2026-04-01
The organization was excellent, and the transfer to and from the port was seamless. The catamaran was comfortable. The staff deserves a special mention – they were welcoming and friendly, 10000% out of 100! They were very attentive, always ready to help, and created a great atmosphere, no matter the weather. Unfortunately, the boat ride was canceled due to the weather, but we were refunded for that part of the tour without any questions asked – that was a relief. The reef itself and Green Island are, of course, beautiful, despite the weather. We weren't able to fully enjoy all the activities, but no one can control the weather.

Reviews: Cairns Silver Swift Agincourt Great Barrier Reef 1-day tour: round-trip ferry + snorkeling + lunch
Guest User2026-03-02
The team provided excellent service, carefully explaining marine knowledge and itinerary precautions on the way there. However, the itinerary was very tight. We arrived at the Great Barrier Reef at nearly 12:00, immediately participated in a semi-submarine tour, followed by lunch, and then snorkeling. Time was limited, and we had to prepare to return to the water around 2:30. I do not recommend participating in any more experiences, as it was very rushed.

Reviews: Snorkelling or Glass Bottom Boat at Green Island from Cairns
Guest User2026-02-14
Beautiful island, if you don’t snorkel though there not much to do. Glass bottom boat is good. Food sold on the island is basic. Not all menu”s are written in other languages with pictures. Overall relaxing day.
