Caesar's Rocks: Ten spectacular coral heads honeycombed with tunnels and caves. The walls and roofs of every cave and tunnel are covered with soft corals in every color of the rainbow; shades of red and yellow, purple and maroon. Huge gorgonias ('sea fans') and black coral trees hang from every coral head and ensure excellent photographs. This is surely an underwater photographers' paradise - schools of batfish, amberjack and shimmering schools of silver pelagic fish merge with turtles and rays. One of the world's ultimate dive spots, a constant delight to divers, conservationists and ecologists.
