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.

Green Island Day Trip from Cairns
Snorkelling about a kilometre from Green Island. A chance to see the coral reef in its full glory and the endless stream of the most colourful fish you have ever seen.

Green Island Day Trip from Cairns
We loved the whole day at Green Island! The boat trip was great and the snorkelling was awesome, we saw a turtle on our second snorkel from the beach. If you're keen to see more while snorkeling, you MUST do the guided snorkel safari tour, it was fantastic!

Green Island & Great Barrier Reef Sailing Cruise from Cairns - only 25 guests
Great crew, really attentive. Various snacks are served during the trip and we had a real feast for lunch on board. Beautiful views and a good spot near Green Island to do snorkeling through corals and fish. The sailing boat experience on the ocean is amazing!

Green Island & Great Barrier Reef Sailing Cruise from Cairns - only 25 guests
The whole day was well planned and memorable, it was a fantastic day. The crew were attentive and helpful, food was great and plentiful. This was my first time snorkelling, the staff helped me overcome the nerves staying with me the whole time. The guided reef tour was amazing. There were only 8 passengers so it was a more personise tour. Thanks again for an amazing day.

Worth the trip but basic snorkelling

Green Island Day Trip from Cairns
Crew were efficient, friendly and welcoming. I have snorkeled a lot and the snorkelling on green Island wasn’t the best but I went at low tide. Definitely recommend high tide so your not too close to the bottom. However, Worth the trip, the boat ride is fun!

Fly to Green Island - Cruise Return
The trip to Green Island was a perfect day. The helicopter ride over was breathtaking with beautiful views. The staff were professional, courteous and helpful. The time on Green Island was relaxing and enjoyable. Many activities were available, including a tour over the reef in a glass bottom boat, snorkeling, walks, and beach time. It was nice to have so much time to ourselves. The packed picnic lunch that was provided was excellent - with too much food. The boat ride back provided a good end to a perfect day.
