This site extends east and west around the island of Siyul Kebir. The reef has an extremely varied profile, with an undulating reef face split by furrows, sandy 'wadis' and big valleys, hollows and depressions. The reef is composed of very dense coral patches. The north side is especially thickly grown, but is subject to the full force of wind and weather, while the south side is more sheltered, offering good snorkeling possibilities on a series of reef patches.

The site is richly covered by a variety of coral types, both hard and soft. Fish life is equally exuberant. The reef here attracts frequent pelagic visitors and the usual reef species. Leopard and nurse sharks have sometimes been spotted on the sand here.
