Dive-site story
Rising sharply from the seabed near the outer edge of Agincourt Reef, Castle Rock is an isolated coral bommie that acts as a beacon for marine life. Divers can spiral slowly around the tower, inspecting deep crevices filled with glassfish before ascending toward the coral-rich crest. Occasional open-ocean currents sweep around the structure, attracting schools of predatory fish that circle into the flow.
Solitary coral pinnacle covered with gorgonian sea fans and whip corals along its deeper flanks
Dense schools of baitfish and sweepers clustered tightly within sheltered undercuts
Cruising pelagic predators including giant trevally and Spanish mackerel in open water
