The name means that this is a reef in the middle of the sea, but close to the island of Siyul. It is also known as Blind Reef because at high tide it is submerged and can be difficult to find. The sea around the reef reaches depths in excess of 50 meters, the reef gently sloping down to around 20 meters before dropping more steeply into the blue. There is the chance to see larger fish such as tuna and barracuda passing in the blue here. Small pinnacles along the drop off abound with smaller fish and there is a good chance to see lion fish and moray eels and maybe a crocodile fish hiding in he sand.
