At a depth of 150ft (46m), this roundish mound of barren rock looms up from the sandy bottom, creating an eerie feeling. The highest point is at a depth of 80ft (25m). It is home to the largest and most seen hammerhead shark schools in Cocos. This legendary seamount is probably one of the most incredible dive sites in the world. No words can describe what you will see at Alcyone. Just come and witness it for yourself.
