Namena Reef, Fiji
Thanks to local Fijian village chiefs protecting and managing this reef, it's home to thousands of species of coral and marine life. Operators visiting sites within Namena Marine Reserve require an admission fee (to be paid in advance) that's used to maintain the mooring buoys and other preservation costs associated to keep the reef exceptionally healthy. Descending into the immaculate waters, swimming with schools of barracuda, gliding past 1000-foot vertical drop-offs, and riding the currents up chimneys while coral snakes quietly follow you gives you serious bragging rights. There’s a reason Jean-Michel Cousteau set up a resort on nearby Vanua Levu island: The diving rocks!
