Green Island is a tropical cay situated in the Great Barrier Reef. Surrounded by white sandy beaches and sapphire blue waters, Green Island is only an hour by boat from Cairns. There are a range of activities to choose from including Scuba diving, snorkelling and even walk underwater with the Seawalker helmet diving. For an exhilarating top-side perspective of the reef, there’s parasailing and scenic helicopter flights too! We chose to snorkel upon arrival and it was amazing.
