All this has made Similan Islands dive sites like "Elephant Head", "East of Eden" and "Christmas Point" justly famous. A world of giant underwater boulders, caves, canyons, narrow passages, some 500 species of hard and soft corals and an amazing variety of marine life including leopard sharks, guitar rays, whale sharks, manta rays and turtles is waiting to be explored.
