Angarosh

Angarosh translates as mother of sharks, and the name reads as a plain statement of function. The reef's crown never breaks the surface; below it, terraced plateaus at roughly 25 and 45 meters act as viewing balconies over deep water where scalloped hammerheads school in the cooler months, silvertips make their abrupt, confident inspections, and grey reef sharks hold the corners. Silky sharks sometimes mob the boat before anyone is even wet. The deeper plateau sits at the edge of recreational limits and is treated accordingly - a brief, disciplined visit with the ascent planned before the descent. Far from ports and rarely dived even in Sudan's best years, Angarosh preserved the feeling most of the Red Sea lost: that the sharks outnumber the divers.

The moment you come for: Silvertip encounters; hammerhead schools off the deep plateau; a reef that belongs to its sharks.

Topography: A small reef whose top sits about 10 meters down, stepping onto plateaus near 25 and 45 meters

Entry: A remote reef on northern itineraries toward Mukawwar Island; dived when weather allows the crossing.

Hazards: Depth on the lower plateau; strong current and exposure; extreme remoteness even by Sudanese standards.

Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
