Reviews: Great Barrier Reef Snorkeling and Diving Cruise from Cairns
Guest User2024-09-14
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: 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.

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.
