Cairns Green Island is a tropical island paradise.


Famous today for its blend of Reef and rainforest, and of course, Guinness World Record holder Cassius the crocodile, Green Island’s fame has a long, impressive history. In 1937, Green Island introduced the world’s first glass-bottom boat. While in 1954, the first stationary underwater observatory opened.

Nature Experiences

Green Island, located off the coast of Cairns, is not just a haven for snorkelers and divers. It is also home to a beautiful rainforest waiting to be explored.

Marvel, too, at the juxtaposition of coastal vegetation and dense, shady rainforest, both only a few metres apart.

In addition to rainforest wildlife, Green Island is a birdwatcher’s paradise, with over 50 land and seabird species.

The rainforest is accessible with easy boardwalk pathways leading visitors on a guided eco-tour of the plant and animal life.

Resort guests can join an informative, guided Eco Walk tour. Self-guided tours can also be planned to suit the length of your stay.

Note: Great Adventures posted their version (PDF) of a simple Eco Walk map with accompanying text explanations that could be replicated.

See our map for more details.


While on Green Island, you can explore only 1.6 kilometres to walk around the island.   Taking your time, you can complete this walk in 45 minutes, leading you on a journey past the island’s vibrant flora and fauna.

But take note – some of the best walks are to be had when the sun goes down. Set out on a moonlit walk to look at the nocturnal happenings in nature, from birdlife to turtles laying eggs.

Guests of the resort can join a guided and informed tour (torches provided). The night sky view is also a good excuse to stay up late.
