Gabr el Bint
Egypt
Gabr el Bint ranks among one of the most attractive sites of North Sinai. With the access by boat, 4x4 or by camel, it is less frequently dived than the other dive sites in Dahab which has left this site in pristine condition. Gabr el Bint means 'The Grave of the Girl' in Arabic. There are two dives possible here. The ledge is riddled with exquisite coral heads that attract numerous reef species, including swarms of anthias, scorpionfish, parrotfish, crocodilefish, surgeonfish, triggerfish, trumpetfish, stingrays and very often a turtle. At the end of the ledge usually is home to a shoal of black and white snappers and twinspot snappers hang here between 5m and 10m. One of the truly breathtaking dives in Dahab.

White Rock
Thailand
The range of life found here is huge and there is something to please every diver. Turtles come here to munch away on soft corals, casting a lazy, half-interested eye at divers. Koh Tao's infamous Titan Triggerfish prowl this dive site too, and some of the largest specimens hang out here. White Rock attracts many hunters: Great Barracuda and Trevally excite the fish making them dart for cover in the plentiful hard corals; Banded Sea Snakes wind their way through the corals searching for their prey. Blue-Ringed and Six-Banded Angelfish swim around in their buddy teams passing Beaked Coralfish, Bannerfish and Pig-Faced Butterflyfish. Look under ledges and outcroppings and you are bound to find a White-Eyed Moray Eel or a Blue-Spotted Ray awaiting nightfall. Under the South buoyline, a large shoal of Yellowtail Barracuda spend their days following divers. Even though White Rock is close to Koh Tao, in season Whalesharks are regularly seen here.
