This marine interpretative center houses a large open tank with one of the few self-contained coral-reef ecosystems in the southern hemisphere—and it's been growing on its own for almost 20 years. Other exhibits include a static display of rare, deepwater coral skeletons and an exhibit explaining the effects of global warming on the planet. Night tours, which begin at 6:30 on Wednesday, Friday, and Sunday, take you by ultraviolet flashlight to view the biodiversity of the fluorescing reef and live venomous animals; the colours the coral produce are astounding. The tours include a four-course seafood dinner, followed by a nocturnal coral reef tour of the exhibitions. Bookings are essential.
