Daedalus Reef

Ninety-odd kilometers off the coast, Daedalus is a lighthouse standing on a reef and nothing else - the most isolated dive in Egyptian water and, in early summer, its most dependable hammerhead rendezvous. Scalloped hammerheads school off the north point from roughly May to August, and the technique is its own ritual: swim out from the wall into featureless blue, hold formation, breathe quietly, and let the schools materialize below like a mobile. The reef repays the crossing even without them. Anemone City on the northern shoulder is a slope of anemones and their fish found in few other places at this scale, the eastern and western walls run with soft coral, and oceanic whitetips take over the boat shadows in fall.

许可证与规定: Marine-park fees; operators generally require Advanced Open Water and logged-dive minimums.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
