You know you've heard of it; Australia's Great Barrier Reef. And now you can experience it. At more than 1,429 miles in length, this natural wonder can be seen from outer space. Board the Island Explorer, a custom-built catamaran, directly from your ship to start your adventure. During this magnificent all-day outing, you'll marvel at how awesome nature is while traveling through Great Barrier Reef Marine Park - an institution committed to protecting a large part of the Reef from damaging activities. Your voyage will take you to the inner-fringing reef, off Whitsunday Islands, for a bewitching snorkeling experience. Nestled between the northeast coast of Queensland, Australia and the Great Barrier Reef, these islands feature an enormous stretch of coral full of mesmerizing marine life, including vividly colored fish, incredible corals, green sea turtles, moray eels and rays. At lunchtime, come up for air to enjoy a delightful meal and dazzling view aboard your splendid sail.
