Chromis Reef (middle) is a shallow Cooper Island reef with sandy patches, coral heads and small overhangs that make it an easy but interesting dive. The route stays gentle and readable, with sea fans and gorgonians on the slope and blue chromis, tarpon, creole wrasse and parrotfish moving through the fishier sections. It suits beginner divers and snorkelers who want a relaxed shore dive with enough structure to keep the reef from feeling flat.
