See more of the Great Barrier Reef when you book this combination of two best-selling cruises from Cairns. Start with a day trip to Green Island, sailing in style on a two-mast schooner with no more than 25 guests on board. Snorkel straight off the boat and after lunch relax or explore the beauty of Green Island. Your second day on the Great Barrier Reef takes you by high-speed catamaran to the outer edge of Upolu Reef and Upolu Cay Reef. With six hours between these two unique reef sites you can snorkel, take an informative adventure drift snorkel tour, see the underwater world without getting wet on a glass bottom boat tour with no rush in your day! Optional diving is available on both days (additional cost, to be booked and paid on the day of travel). You will see so much in two days and get great savings by booking these tours together.
