1. Cairns: Full-Day Glass Bottom Boat Snorkel Tour
Discover the lush rainforest of Green Island on this full-day snorkel tour and encounter some of the many marine animals that call the island home. Climb aboard the modern, air-conditioned catamaran "Reef Rocket" to cruise over to this idyllic part of the Great Barrier Reef, and enjoy a full-day reef tour just 45-minutes from Cairns. Snorkel and dive among the reef fish and coral gardens, or stay dry on a spectacular semi-submersible submarine or glass-bottom boat to discover the underwater life in comfort. Alternatively, simply laze on the white sandy beach and soak up the sun.
