Thomas Reef is the most colourful reef in the Straits of Tiran.
Dives are usually made on the eastern side of the reef where the water is calmer. When conditions are good and if air consumption permits, it is possible to circumnavigate the reef. The reef reaches from 0.5 to 28m where it forms a plateau. There is a row of Gorgonian Fans that house Long Nose Hawk Fish, different species of Nudibranchs and Pipe Fish. Near this spectacular site is a small soft coral garden. Here divers have a good chance of seeing Turtles having lunch. On the wall itself you find small pinnacles encrusted with coral and with lots of Anthias. Looking away from the reef divers may see Unicorn Fish, Redtooth Trigger Fish, and schools of Jacks and Trevallies.
