Situated directly on the Great Barrier Reef, Heron Island Resort is reachable only by boat, seaplane, or helicopter. Whichever way you to choose to arrive, transfers are sure to be scenic, with views of the occasional whale or turquoise reef formation. Once on the island, expert pure serenity—day-trippers are not allowed, there isn’t any cell phone reception, and rooms are television-free. Even the lowest tier Turtle rooms include private balconies or terraces with garden views, while the exclusive one-bedroom Beach House features its own boardwalk to the beach. Unlike at many resorts in the area, some rooms even have air-conditioning. Guests can also look forward to more than 20 renowned dive sites just minutes from the jetty, including the Heron Bommie, which Jacques Cousteau named among his top 10 favorite spots in the world.
