Reviews: Cairns: Green Island Snorkelling or Glass Bottom Boat
Guest User2026-03-16
Enjoyed boat trip, had a great snorkel for a couple of hours and an informative glass bottom boat ride with lovely guide. All in all a great day out.
Reviews: Great Barrier Reef Snorkeling and Diving Cruise from Cairns

Fantastic day with great staff who look after every need. We stopped at two reefs and had a great deal of time at each. I felt very safe and secure throughout, they really look after everyone. Great lunch too with options for everyone. The fish and reef were beyond incredible and I only wish I could have stayed longer in Cairns as I would absolutely repeat this tour!
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 Great Barrier Reef 1-day tour with Silverswift [Optional scuba diving]

Overall, the experience was good. I went on three certified deep-sea dives to different places, but saw similar things. The price was a bit high, probably because of the excellent service and the increased prices on meals. All diving equipment was provided, so there was no need to worry about extra charges.

Interesting but more information regarding times and dates of driving/riding in the tanks would have been beneficial
