Site details

A signature Daymaniyat dive on three rocky outcrops within the nature reserve, about 18 km offshore from the Muscat coast. Sloping reef and boulder terrain runs from the shallows to roughly 20-22 m, decorated with hard and soft coral and frequently patrolled by turtles, rays and large schools of fish. Conditions are usually easy with low to moderate current, making it a favourite for both training and fun dives. Marine life density is high and whale sharks pass through in the warmer months.
