If you’re dreaming of a day that combines vibrant marine life, lush rainforest, and a laid-back beach vibe, a trip to Green Island might just be your ideal getaway. This tour offers a chance to explore one of the most iconic parts of the Great Barrier Reef, right from Cairns, with options to snorkel, take a glass bottom boat tour, or simply unwind on the sandy beaches.

We haven’t personally experienced it, but the reviews and itinerary paint a pretty appealing picture for anyone craving a mix of adventure and relaxation.

What we really like about this experience is the opportunity to see the reef’s beauty from different perspectives—whether you prefer gliding through the water with snorkel gear or staying dry on a glass bottom boat. Plus, the inclusion of a rainforest walk and the island’s amenities like pools and eateries make it feel more like a full-day escape rather than just a quick trip.

A day on green island was amazing. We chose the snorkelling option (did have to pay extra for a stinger suit but well worth it) we then saw the crocodiles and had lunch which was really good too. Perfect day – so many turtles and fish! 100% would recommend.

Transport to Green Island with Great Adventures was fantastic. The staff were so friendly and helpful, and I had the an amazing day exploring the island. We even spotted turtles, stingrays and loads of big fish ! It was such a great day out!

What Makes This Tour Stand Out?

Cairns: Green Island Snorkelling or Glass Bottom Boat - What Makes This Tour Stand Out?

The Green Island tour is a thoughtfully planned outing that balances marine exploration and island leisure. It’s designed to give you a taste of the reef’s vibrant ecosystem without the need for extensive diving skills or equipment. The highlight for most visitors is the glass bottom boat—a gentle, informative ride that offers stunning views of the coral gardens and marine life without getting wet. As one reviewer appreciated, “The glass boat was a nice adventure for us who don’t snorkel.”

The ability to snorkel directly from the beach is another perk, offering an easy entry point into the reef. Snorkel gear is provided, and the calm, shallow waters make it accessible for beginners. Multiple reviews mention seeing a variety of fish, sea turtles, and even reef sharks, which speaks to the reef’s incredible biodiversity. For instance, one guest shared, “Having never snorkeled before, I was surprised to see such a huge variety of wildlife, including sea turtles and sharks.”

Apart from the aquatic adventures, the island itself is a draw. It’s a 6,000-year-old coral cay with a rainforest, offering a lush walking experience. Visitors can enjoy a leisurely self-guided walk along well-marked paths, reading informational boards about the local flora and fauna. The rainforest adds an unexpected element of greenery, making the island more than just a beach destination. From the reviews, it’s clear that many appreciated the well-maintained, clean environment and the opportunity to escape the mainland’s bustle.
