One day on the Great Barrier Reef is simply not enough, so bedding down on the reef on a luxury boat allows for an extended visit. Moored at the outer Great Barrier Reef, where the coral and marine life is most prolific, Reef Encounter offers 21 double and twin cabins and packages ranging from one to three nights. On longer stays guests can learn to dive, snorkel to their heart’s content or simply view the underwater scenery from a glass-bottom boat. Back on Reef Encounter, there’s a dining saloon and bar, sundeck and games area. For more information, head here.
