Explore the Outer Great Barrier Reef aboard a luxurious sailboat on this full-day snorkeling tour from Port Douglas. As the boat sails for the reef, relax on the spacious upper deck and enjoy morning tea. At the snorkel site, don the provided equipment and jump in, taking advantage of a guide's instruction if you wish. Alternatively, a coral-viewing boat is available for those who don't wish to swim or snorkel. A buffet lunch and afternoon tea round out this seamless tour.
