The Brothers Islands: Sharks, Sheer Walls and Century-Old Wrecks in the Egyptian Red Sea
Roughly sixty kilometres off the Egyptian mainland, two specks of rock interrupt the open Red Sea. The Brothers Islands, known in Arabic as El Akhawein, are the exposed summits of steep pillars that climb from deep water to just above the surface. There is no lagoon, no sheltering reef flat, no gentle slope: the sea floor plunges away on every side within a few fin kicks of the shore. That geography is precisely why divers cross hours of open water to get here. Nutrient-rich currents sweep past the islands, feeding walls of soft coral and drawing in the pelagic hunters, above all sharks, that have made this remote outpost one of the most storied dive destinations in the entire Red Sea.
Two rocks alone in the open sea
The Brothers sit far from any coastal reef system, isolated in blue water east of the town of El Quseir. Big Brother, the larger of the pair, is a low, elongated island crowned by a working lighthouse; Little Brother, its smaller sibling, lies a short distance away to the south-east. Neither island offers any natural anchorage, and both are fully exposed to wind and swell from every direction. Because they stand alone in deep water, the islands act as oases. Everything that drifts, hunts or migrates through this part of the Red Sea eventually funnels past them. Plankton-rich water hits the walls and rises, coral and fish life flourishes in the flow, and predators patrol the edges where reef meets open ocean. For divers this means an intensity of life that fringing reefs near the coast rarely match, but it also means conditions shaped by the open sea: currents that can switch strength and direction between dives, surface chop, and long blue-water safety stops drifting off the reef. The Brothers reward experience and punish complacency, which is a large part of their reputation.
Big Brother and its Victorian lighthouse
Big Brother is instantly recognisable from miles away thanks to the stone lighthouse that rises from its centre. Built by the British in the 1880s, when the Red Sea was a crowded imperial shipping lane between the Suez Canal and Asia, the tower is still staffed and still working today. Its presence is a reminder of why the wrecks below exist at all: these low islands were, and remain, a genuine hazard to navigation on a busy sea route. Underwater, Big Brother is essentially one continuous wall broken by two plateaus. The north end takes the brunt of the prevailing current and holds the densest fish action, with schooling snapper, trevally hunting in the blue and grey reef sharks stacked in the flow. The southern plateau offers a slightly gentler profile, hard coral gardens and a good chance of thresher sharks rising from deeper water in the early morning. Drift diving is the norm; boats drop divers up-current and collect them wherever the reef and the sea decide the dive ends.
The Numidia: a wreck that pours down the wall
At the northern tip of Big Brother lies one of the most dramatic wrecks in the Red Sea. The Numidia, a British cargo steamer, struck the island in 1901 and settled against the near-vertical reef, where she remains draped down the wall like a curtain. The shallowest wreckage begins only a few metres beneath the surface, while the stern falls away far beyond recreational depth limits, so every diver, whatever their certification, sees only a slice of her. More than a century of soft coral growth has transformed the steel into reef: her frames are furred in purple and orange dendronephthya, anthias swarm the masts, and the railway wheels she was carrying still lie scattered on the coral where they spilled. Because the wreck sits exactly where the current splits around the island, the diving is rarely still. On a good day you hang in the flow beside a hundred-year-old ship while grey reef sharks cruise the blue behind you, an image that sums up the Brothers better than any brochure.
The Aida, the lighthouse supply ship
A short swim along the wall from the Numidia rests Big Brother's second wreck, and its story is tied directly to the lighthouse above. The Aida served as a supply vessel for Egyptian lighthouse stations, and in 1957 she was lost against the island while attempting to land personnel in rough weather. She now lies on the steep slope with her shallower sections within reach of experienced recreational divers and her deeper structure continuing down the wall, a profile that has made her a favourite among technical divers who can follow the hull into the gloom. Like her older neighbour, the Aida has been claimed by the reef, her steel softened by decades of coral growth and patrolled by the same anthias, groupers and passing jacks. Diving two historic wrecks on a single wall, both born of the same hazardous rock, is a rare privilege, and it gives Big Brother a sense of layered history that few offshore reefs anywhere can offer.
Little Brother: gorgonians and threshers
Little Brother may be the smaller island, but many divers quietly rate it the better dive. Its walls are astonishingly lush, with terraces of gorgonian sea fans on the eastern side that rank among the finest soft coral scenery in the Red Sea, glowing in the morning light like a submerged forest. The island is compact enough that, in kind conditions, a single dive can cover a large portion of its circumference. The northern end widens into a plateau that acts as the island's shark theatre. Scalloped hammerheads school off the point in the cooler deep water, pelagic thresher sharks with their extraordinary scythe-like tails rise to visit cleaning stations around dawn, and grey reef sharks hold station in the current for much of the year. In late summer and autumn, oceanic whitetips arrive and patrol boldly just beneath the surface, often circling the moored boats themselves. Few places concentrate so many shark species around such a small piece of rock.
A protected marine park, reached only by liveaboard
The Brothers belong to Egypt's offshore Marine Park islands, a protected group that also includes Daedalus Reef, Zabargad and Rocky Island. Protection comes with rules that shape every trip: access is by licensed liveaboard only, there are no day boats this far out, night diving is not permitted, and operators typically require divers to hold an advanced-level certification with a solid logbook, commonly around fifty dives. Itineraries usually depart from Port Ghalib or Hurghada and spend several days at the islands, with crossings that can be rough when the wind is up. The diving itself demands honest self-assessment. Currents are the engine of everything good here, but they must be respected, and every diver should be comfortable deploying a surface marker buoy in blue water. In return, the Brothers deliver the essential Red Sea distilled: vertical coral walls, genuine history in steel, and the flicker of a shark's silhouette at the edge of visibility.

The Brothers are a single stop in a Red Sea full of walls, wrecks and offshore pinnacles, and they make the most sense when you see where they sit, alone in open water between the Egyptian coast and the shipping lanes.
