One of the 7 natural wonders of the world—the Great Barrier Reef definitely demands a deeper day-long immersion (or submersion). This exciting full-day tour will take you to experience two very different reef environments; combining a 2-hour visit to a 6000-year-old coral cay and 3 hours to experience the wonderful marine diversity of the Outer Reef.

Start your day by boarding a modern fast catamaran for a 45-minute cruise to beautiful Green Island. The best of both worlds, this Marine National Park offers lush rainforest jungles above the water and coral gardens below. On the island, take advantage of snorkeling directly from the beach and maybe meet one of the local green sea turtles (equipment provided), explore the surrounding flora and fauna, or simply laze on the pristine white-sand beaches.

At 11:30, it’s time to depart Green Island, where the adventure continues as you cruise to Great Adventures’ exclusive outer reef activity platform, a spacious, floating pontoon where a myriad of activities awaits. Head to the underwater observatory for an intimate look at the local marine inhabitants, or don your snorkel gear and dive in for a more personal introduction.

Savor a delicious buffet lunch, then hop into a semi-submersible vessel for another up-close view of the vast and varied coral formation and tropical species that call the area home. While at the Outer Reef, some exciting optional activities include scuba diving, the unique Scuba Doo underwater scooter, guided snorkel tours, and even scenic helicopter flights.
