Reviews: Cairns Magic Reef Great Barrier Reef 1-day tour with snorkeling, lunch, glass-bottom boat, and semi-submarine
Guest User2026-10-26
We loved everything. The staff was great, and everyone was very helpful and friendly. We arrived at the pontoon, where we could swim and sunbathe freely, look through the glass wall, and ride on the glass-bottomed boat. We had plenty of time, the lunch was delicious, and they even gave us donuts and crackers along the way.★

Reviews: Cairns Great Barrier Reef + Fitzroy Island 1-day tour
Guest User2026-10-25
The ferry crew had no issues. They brought us in, gave us fins and a mask, though without trying them on, and told us where to get lunch. It's important to remember that coral flip-flops are a must on Fitzroy Island. The entry into the water there is very difficult, as the coral immediately encroaches. We saw a stingray on the far beach, but the coral on the near beach is more beautiful.★

Reviews: Cairns Big Cat/Green Island Great Barrier Reef Cruise [Short Trip/Snorkeling/Glass Bottom Boat]
Guest User2026-09-12
Very convenient for elderly people or young kids that can't snorkel or head into the waters to view the Great Barrier Reef. Bring basic swim gears at least even if you're not going for a swim. Worth going for a walk in the waters or a light dip. If you're not keen on buffet on a boat or the restaurant choices, bring your own lunch, or just your own snack to enjoy on the island. Go for a walk on the other end of the island. Different trails to suit different stamina. If elderly or young kids is going, it may be much comfortable to book the return boat /cruise to and from Green Island, the lunch buffet /the lunch package with Emerald Restaurant / food voucher with 1 of the eateries, book the glass bottom boat ride in lieu of the snorkeling, and the semi submarine too.★

Reviews: Cairns Big Cat Green Island Great Barrier Reef Cruise Half-Day Tour - Optional Morning/Afternoon Snorkeling & Glass Bottom Boat
Guest User2026-09-07
A great half-day tour! Everything was on schedule! We had a flight that day, so it was important to get back to port on time. Everything went smoothly and without any delays! The island itself is small, so two hours was enough for snorkeling and a hiking tour!★

Reviews: Osprey Evolution 1-day tour for Great Barrier Reef diving with unlimited snorkeling, helicopter rides and deep diving available as add-ons
Guest User2026-06-03
A huge thank you to the only instructor who speaks Chinese 🥹! Seeing that I'm not a strong swimmer, she proactively helped me and led us on a guided tour of the nearby corals and marine life. Even though I was a little scared and clung tightly to my swim ring, she patiently guided me. The instructors on the boat were all very friendly, making the whole trip very relaxing, and the food on board was delicious too 😊
