StandoutExceptional marine biodiversity

Rainbow Rock sits at a shallow 21 metres, making it a good intermediate dive. It's a rocky site, which means you'll spend your time exploring crevices and overhangs rather than big coral structures. Look for moray eels tucked into the rock and schools of fusiliers circling the pinnacles. It’s a solid dive for those who enjoy hunting for macro life and aren't chasing big pelagics.
