The Mamanucas' most famous sites include Supermarket, where divers encounter Grey reef, White tip reef, and Black tip reef sharks. At Gotham City, a large array of fish and brilliant soft corals reside among three pinnacles. You can also see parts of a crashed B26 Bomber and the swim-throughs and Clown fish garden of Plantation Pinnacle, patrolled by Grey reef sharks and occasional barracuda. There are sites for every level of experience and the fantastic visibility here (up to 50 meters) makes this a great place to learn.
