The Minerva Ledge Area sits in the Andaman Sea, roughly eighteen kilometres east of Havelock Island, and is only accessible by boat. All four sites, including Minerva Ledge itself, Jackson's Bar, Johnny's Gorge, and Broken Ledge, are reef and drift dives suited to intermediate and advanced divers. The ledge is a large flat coral garden system with strong currents that make drift diving the norm; Jackson's Bar adds a drop-off topography at depth. Visibility is generally good and can extend well beyond twenty metres. Species recorded include blacktip and whitetip reef sharks, whale sharks, green sea turtles, napoleon wrasse, and batfish.
