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: 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: Grand Kuranda including Skyrail and Kuranda Scenic Railway
Guest User2024-07-22
Me and my family took an army duck tour last sunday and we had a really good time. We would like to compliment your new guide Mark. He had really good and interesting comments about nature and wildlife that made the tour fun and enjoyable. We also loved other activities in Kuranda, like the Pamagirri Aboriginal experience. We learned how to throw a boomerang and we enjoyed the presentation of Aboriginal coulture. The scenic Railway had some really good views and the train to Cairns was most enjoyable. Sending love from Slovenia.
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.
