The reef extends around the island of Gross Siyoul (Big Siyoul) and is very diverse
Sometimes sand valleys (wadis) interrupt the reef, then there are overhangs and crevices to explore.
An overabundant growth of corals and countless fish amaze the diver. The dives with a mostly fast current lead to the northern tip.
- Sharks and large rays are often seen in the deeper water, while schools of sweetlips and masked butterflyfish can be seen in the shallower water.
