Reviews: Cairns Reef Magic Great Barrier Reef 1-day tour with meals | helicopter/diving/snorkeling
Guest User2026-09-10
The entire Great Barrier Reef trip was very fulfilling, and the crew's service was excellent. Remember to check in for the helicopter as soon as you board; we were among the first to check in. We took the helicopter once we reached the outer reef. The weather wasn't great on the way there, but it cleared up when we took the helicopter, and the colors of the Great Barrier Reef were truly beautiful. The food on board was also quite good (especially the fruit, which was very good; I felt a bit dizzy at the time, and the fruit made me feel much better). There was some free bread on the ship on the way there and back. Before leaving, all the crew members would stand in a row to say goodbye. You definitely have to take a helicopter trip! Unfortunately, I didn't go snorkeling, but my wife and child went into the water. They said they could see fish underwater, and I took picture 2 from the bottom glass of the ship. The helicopter registration staff on the ship spoke Chinese, and there were also other staff who spoke Chinese, which was great. If you want to try other submarine activities, you can check the ship's schedule and arrange your own time accordingly. Just go and queue up when it's time. Each activity is located in a different area on the ship. Also, please note that you should wear a light swimsuit. The rash guard on the boat is necessary if you're going during the summer holidays; it might be a little chilly without one, but it will be just right. There are plenty of rash guards available in different sizes. You don't need to bring your own fins, snorkel, or goggles; there are plenty. I only brought my own goggles and snorkel. If you're concerned about hygiene, you can bring your own snorkel. The lockers on the boat are small, so just grab something convenient to pack your things. Generally, no one uses them; everyone's busy enjoying themselves.★

Reviews: Cairns Green Island Great Barrier Reef Big Cat half-day tour snorkeling/glass bottom boat
Guest User2026-10-27
I signed my father up for the trip. He's 63 and traveling alone, and he was completely satisfied with the itinerary. He had a perfect snorkeling experience, truly felt the beauty of Green Island, and the crew took excellent care of him, even checking on his physical condition before the snorkeling session.★

Reviews: Cairns Magic Reef Great Barrier Reef 1-day tour with snorkeling, lunch, glass-bottom boat, and semi-submarine
Guest User2026-10-29
A full-day trip to Magic Reef was the best thing that ever happened to us in Cairns. The boat takes us to a pontoon, and for five hours we enjoy everything we can, snorkeling, diving, a glass-bottom boat, and even a fish-feeding show. We had a delicious lunch with fruit and shrimp. We were touched by the friendliness of the crew; everyone was so nice and ready to help at any time.★

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 Great Barrier Reef + Fitzroy Island 1-day tour
Guest User2026-10-27
I traveled to Cairns with my father, and we booked different itineraries on the same day. He didn't want to walk, so he went to Green Island on the Big Cat, while I chose Emerald Island because I wanted to experience some rainforest and kayaking. It was definitely worth the trip. Emerald Island has a very diverse landscape, from the Jellyfish Sea to the beach to the rainforest. Overall, I was very satisfied with the trip!★
