Shag Rock lies approximately one mile to the west of the Sha ab Ali lagoon. It is often overshadowed by its more famous neighbour, The Thistlegorm, but is nevertheless a first rate dive. At the northern end lies the wreck of the Kingston. At the southern end of the reef is a shallow plateau, scoured by strong currents and extremely rich in sea life. The prevailing current here comes from the north, splitting around the wreck and running down either side of the reef at anything up to four knots. The best dive starts at the wreck. It is only accessible in calm seas. Take your time to examine the stern. The rudder and propeller are very photogenic. On the top deck is a large steel spare propeller. The front of the wreck is largely disintegrated, most likely on impact, but the boilers and condensers of the engine room are still present as are many brass portholes. Living on the wreck are many inhabitants of the shallow reef table. Sohal surgeonftsh, rabbitfish and nudibranchs which graze off the carpet of algae on the wreck. The wreck is small, so when you have seen enough, head off down the western wall of Shag Rock. The reef is extremely rich, diverse and untouched. Grouper, yellow snapper and jackfish abound. In the blue off the wreck is also one of the most likely places for encounters with dolphins. To dive the south plateau, drop in about 200 m up the west wall, the east wall is strewn with garbage from the construction of the beacon. Drift back with the current. You will find a sandy slope down to 25 m, scattered with coral bommies. Turtles, morays, groupers and potato cod are common inhabitants. White-tip reef sharks hide under the table corals. Dolphins and even grey reef sharks are occasional visitors to this plateau.
