It is fair to say that the best diving can often be found in some of the most unexpected places. When one thinks of the Sinai, the immediate image is of the spectacular vertical drop offs of Ras Mohammed, teeming with fish life. Venture further north and the canyons and blue hole of Dahab come to mind. But further north still and you have an entirely different kind of diving, the sort that allows you to get close to some of the rarer and most colourful of the Red Sea’s inhabitants.
