A glass-bottom boat, sea kayak, dive or snorkel tour will get you to the outer reef and the playgrounds of dugongs, dolphins, turtles and graceful manta rays. There’s also the option to hop aboard a deep-sea fishing charter or a whale-watching tour to witness one of the world’s longest whale migrations (June to November). Or get your kicks on dry land, with an off-road quad biking tour along the coast.
