Site details

A submerged rock pinnacle lying roughly 4 km south of the easternmost Daymaniyat island (Hayut), just outside the formal nature-reserve boundary, reached by a 45-60 minute boat ride from Muscat marinas. Divers descend the mooring line to the top of the rock at about 7 m and follow the wall north or south over a sand chute down to a plateau at 22-24 m. It earns its name from dense schools of snapper, jacks, batfish, barracuda and red-toothed triggerfish that crowd the rock, with turtles and rays on the sand. Currents are usually mild and visibility is good in summer, making it suitable for most certified divers.
