Today brings you face-to-face with one of the world’s great natural wonders – the Great Barrier Reef, a UNESCO World Heritage-listed marvel and the largest coral reef system on the planet. Step aboard a high-speed catamaran and set out across turquoise waters before choosing how to experience this extraordinary ecosystem up close. Slip into the water to snorkel among vibrant coral and fish in the Great Barrier Reef (equipment provided), or remain dry aboard a semi-submersible, where an underwater observatory offers a window into the reef’s thriving marine life. Along the way, your local guide shares insights that bring this living world into sharper focus. A buffet lunch, plus afternoon tea and coffee, complete the journey before you cruise back to Gimuy (Cairns), the reef still fresh in your memory.
