Reviews: Cairns Great Barrier Reef Fitzroy Island 1-day tour with optional snorkeling/guided snorkeling
Guest User2024-11-07
Second time Fillroy Island. When I snorkel alone last time, I saw sea turtles 𓆉. This time, when I went to the beach behind the island with my daughter, I saw Napoleon fish 〜\ (^ o ^) / I was lucky.
Reviews: Cairns: Great Barrier Reef Cruise & 10 Minute Helicopter
Guest User2025-12-28
The price point for this activity was great! We enjoyed the boat ride out to pontoon on the Great Barrier Reef. We booked the 10 Min Helicopter ride and highly recommend it! Our pilot, John, was exceptional. He was friendly and fun - the sights of the reef above were stunning. On the pontoon, you could snorkel or dive with the fish into the Great Barrier Reef. Highly recommend doing the semi submersible as well. The lunch buffet was decent, though if you don’t time it right, the food will be gone quickly. I just wish we had more time on the excursion!

Glass bottom boat was excellent, due to the rain the water was a bit murkier but we saw lots of marine life - fish, turtles, reef sharks and coral- excellent knowledge from guide
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.
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!
