The Basics

As one of the most easily accessible islands in the Great Barrier Reef, Green Island is a popular choice for day-trippers from nearby Cairns. The Green Island resort offers everything you need to explore the island’s underwater wonders, whether you fly in by seaplane or sail out across the reef. As well as swimming, snorkeling, scuba diving, and seawalker helmet tours, there are island reef cruises, glass-bottom boat tours, and semi-submarine excursions, the latter of which offer the chance to peek under the ocean without having to dive in.

Once in a lifetime experience
It was the first time on this trip and I had ever gone snorkelling before and it was breathtaking! My partner and I had an amazing time and managed to see a reef shark and a stingray!

Ocean Free Green Island & Great Barrier Reef Snorkel Cruise, Cairns 25 guests
Other than sailing through Cyclone Tiffany… it was a beautiful day and the weather cleared up for Green Island and while we were snorkelling which was fantastic. We got to swim with a few turtles, see heaps of different fish and saw a black tip shark 🦈. The crew was amazing and the food was great and very accommodating considering the conditions

Green Island Day Trip from Cairns
Green Island is a good place to visit. The ferry trip is good. I have booked online with Viator which should be including glass bottom boat with a higher price. However when I check in, they say that my trip is only having ferry return. Not including any activity. Finally they allowed us to have the glass bottom boat trip. This shows that there is some tricks in between Viator and big cat.

Green Island Discovery Including Glass Bottom Boat Tour Departing Cairns
All the staff were awesome and we were able to sit on the front of the Cat for the trip over. Island is beautiful just sad to see so many things shut down due to lack of tourism at the moment. We did the 10:30-4:30 trip, definitely didn’t need any longer.

Fantastic day sailing (sometimes just with the sails) to the surrounding reef off Green Island. The crew were brilliant and gave each guest their full attention to enjoy the day. Guests were a great crowd with an anniversary & 3 birthdays to celebrate. After a glorious day of snorkelling we sailed back to Cairns with birthday cake and bubbles. Special thx to crew "welsh" Liam, Matt & Pascal for such a fab day !
