The larger of two isolated pinnacles in the open Red Sea, ringed by walls, topped by a Victorian lighthouse and carrying two wrecks on its northern end.
Big Brother is the larger of the two Brother Islands (El Akhawein), a pair of isolated rock pinnacles rising out of deep open water and declared natural protectorates in 1983. It is a small island with a Victorian stone lighthouse standing about 32 m above it, and walls that fall away on every side into blue. There is no shore diving, no day-boat option and nothing on the island: the site is reached by liveaboard on an overnight sail, roughly 150 km south-east of Hurghada (about 8 h) or 125 km north of Marsa Alam (about 6.5 h). Little Brother lies a few minutes away by boat.
Two wrecks lie on the island's northern end and both belong to this site rather than to some separate reef. The Numidia, a 130 m British cargo steamer lost in 1901, stands on the steep northern slope with her bow in about 8 m and her hull running down past 45 m to a stern and propeller reported at 80 to 90 m — far beyond recreational limits. The Aida, a 75 m transport lost in 1957, lies nearby off the same end; published depths for her disagree (a bow at 30 m and a stern past 60 m in one guide, shallow structure to 60 m in another, 15-45 m in a third), so treat any single figure with suspicion. Both are coral-covered, and current on both can be severe.
Recreational diving here runs from about 5 m to a little over 40 m against the walls, with visibility quoted at 20-30 m and water between 23 and 30 C. This is one of Egypt's genuine shark sites: oceanic whitetips, grey reef sharks, silvertips and hammerheads are regular, and threshers are reported particularly in autumn and winter. The occurrence record for the island reflects the reef side of the same story — oceanic whitetip appears in it directly, alongside Napoleon wrasse, coral grouper, black-and-white snapper, bluefin trevally, barracuda and dense anthias.
OW
Liveaboard only — no day boats reach the Brothers. Trips leave from Hurghada or from Marsa Alam / Port Ghalib and involve an overnight sail: roughly 150 km and about 8 h from Hurghada, or 125 km and about 6.5 h from Marsa Alam. Some itineraries board at one port and disembark at the other. There are no facilities on the island.
Access to the site runs through a local operator.
Operator requirements vary. Master Liveaboards asks for Open Water or equivalent plus a minimum of 30 logged dives on its Brothers, Daedalus and Elphinstone itinerary; dive guides describe the site as intermediate to advanced. Given the current, the depth and the blue-water pickups, treat 30 dives as a floor rather than a recommendation and expect some operators to ask for more.
The Brother Islands were declared natural protectorates in 1983 and sit inside the Egyptian Red Sea marine-park system. A government reef tax is payable on board — Master Liveaboards quotes USD 90 per person for a 7-night trip as of 2026, set at embarkation and subject to change by local decree. Night diving is prohibited inside the marine park. Gloves and touching the reef are prohibited across the Egyptian marine parks. Recorded 2026-08-07.
Liveaboard itineraries to the Brothers run from around April to November. Thresher sharks are reported particularly in autumn and winter; oceanic whitetips, grey reef sharks, silvertips and hammerheads are described as regular rather than seasonal in the sources we read, so we have not recorded specific peak months. Winter brings cooler water and rougher crossings.
Open ocean around an isolated rock. Walls run north to south and current runs with them, strong to very strong and severe at times on the wrecks. Visibility is quoted at 20-30 m and above; we record 20 m. Water is 23-30 C with reported thermoclines. Recreational profiles run from about 5 m to a little over 40 m. Surface conditions are exposed and the crossing is an overnight sail.
On current: Current is the defining condition and it is described as strong to very strong, running along walls that lie north to south, and as capable of being severe on both wrecks. Visibility is quoted at 20-30 m by one guide and 30 m plus by another; we record the conservative 20 m. Water runs 23-30 C, and serious thermoclines are reported, so bring more exposure protection than the surface temperature suggests.
By liveaboard only — no day boat reaches the Brothers. Trips sail overnight from Hurghada (about 150 km, roughly 8 h) or from Marsa Alam and Port Ghalib (about 125 km, roughly 6.5 h), and some itineraries board at one port and disembark at the other. There is nothing on the island itself.
Two, both on the northern end. The Numidia, a 130 m British cargo steamer lost in 1901, stands on the steep north point with her bow around 8 m and her hull running down past 45 m to a stern reported at 80-90 m. The Aida, a 75 m transport lost in 1957, lies off the same end. Both are coral-covered and current on both can be severe.
No, regardless of what the paperwork allows. Master Liveaboards' Brothers itinerary asks for Open Water plus a minimum of 30 logged dives, and guides rate the site intermediate to advanced — but the current is strong to very strong along walls that drop into open ocean, the wrecks run past recreational depth, and pickups are in blue water off a zodiac. Treat 30 dives as a floor.
Strong, and described as very strong or severe on the wrecks. The walls run north to south and the current runs with them. This is an isolated pinnacle in open ocean, so there is nothing downstream to stop on — a delayed SMB and a disciplined drift plan are the whole safety margin.
Oceanic whitetips, grey reef sharks, silvertips and hammerheads are all described as regular at the Brothers, with thresher sharks reported particularly in autumn and winter. Oceanic whitetip also appears directly in the occurrence record for this island, alongside Napoleon wrasse, bluefin trevally and barracuda.
Yes. The Brothers have been a natural protectorate since 1983 and sit inside the Egyptian marine-park system. A government reef tax is paid on board — Master Liveaboards quotes USD 90 per person for a 7-night trip as of 2026, fixed at embarkation and subject to change by local decree. Night diving is prohibited inside the marine park, and gloves are not permitted.
Depths from about 5 m to a little over 40 m on the walls, visibility quoted at 20-30 m and above (we record the conservative 20 m), and water between 23 and 30 C with serious thermoclines reported. Surface conditions are open-ocean and the crossing is an overnight sail, so trips can be reshaped by sea state.
Better than inshore. HEPCA's Bleach Watch report on the 2024 event found bleaching increasing north to south along the Egyptian coast but noted that sheltered and inshore reefs bleached more than exposed offshore ones — which is what the Brothers are. Preliminary 2025 recovery was projected at 75-88%.

The 1901 steamer Numidia, standing on the north point of Big Brother with her bow at 8 m and her hull running down the slope past recreational limits.
The eastern route around the one island called Big Brother: a sheer wall dropped from a zodiac and drifted south onto the plateau.
The southern route around the one island called Big Brother: the plateau off its south tip, dived at dawn for threshers.
A 170 m rock in open ocean with walls falling past 700 m, a 40 m plateau off its northern tip, and current that routinely runs 3 to 4 knots.
A boat drift on the wall just north of El Quseir town: free descent, along the wall, out over the plateau to the drop-off.
A plateau at about 20 m off Ras El Quseir carrying one continuous field of anemones, which is why guides call it Nemo City.
