Offshore Red Sea island duo reached only by liveaboard, with sheer coral walls, reliable oceanic whitetips, seasonal hammerheads and two historic wrecks.
Last updated July 2026

The Brothers are two tiny offshore islands in the Egyptian Red Sea, roughly 67 km out from the coast at El Quseir and reachable only by liveaboard. There is no town here and no shore base; every dive runs from the boat and its zodiacs. You sail an overnight crossing, dive through the day, and the islands usually come packaged with Daedalus and Elphinstone on the classic offshore safari known as BDE. What you cross the open sea for is sharks. Oceanic whitetips patrol the walls year-round, scalloped hammerheads school in the blue in summer, and threshers rise to a dawn cleaning station, among the most reliable big-shark diving anywhere. The islands are a marine protectorate managed by the Egyptian Environmental Affairs Agency, and in 2023 were recognised as an Important Shark and Ray Area for their oceanic whitetip aggregations, among the largest in the Red Sea1.
Big Brother is the larger island and the headline. It carries a working 1883 lighthouse, its original Chance Brothers lens still wound by hand2, and two historic wrecks grown into its coral wall: the deep 1901 steamer Numidia and the more intact 1957 tender Aida. Little Brother, a kilometre south, is the smaller and purer wall, prized for soft coral and a dedicated shark plateau. The diving is committing. Walls drop sheer past 60 metres with no shallow shelf. The current runs strong and can pull divers down, and at peak season the islands get busy. Most divers come knowing the sharks are a gamble, not a guarantee, and rate the place anyway.
Diving the Brothers is restricted to licensed liveaboards that hold marine-park permits, so you book a boat and a route, not a day trip. Dedicated Brothers trips run five to seven nights; the combined BDE and North-and-Brothers itineraries run seven to ten. The crossing from Hurghada is seven to nine hours of open sea, usually sailed overnight, so pack seasickness tablets. Bring a full Egyptian visa: the Sinai-only stamp used for shore towns like Dahab does not cover these offshore reefs.
Operators expect advanced certification and a solid logged-dive history before they will take you here, and the marine park sets a minimum experience bar. This is no place to log your first deep, current-swept dives. A marine-park fee is bundled into the trip price. Night diving is not allowed, and rough weather can close the islands, so itineraries often list them as conditions permitting. The best window is October and November for clear water and reliable whitetips, with hammerheads peaking May to October.

The more diveable of Big Brother's two wrecks: a coral-blanketed 1950s Egyptian lighthouse tender lying down the reef wall, intact and fish-thick.
The larger Brothers island: sheer Red Sea coral walls, a working lighthouse, reliable oceanic whitetips, and two historic wrecks on one reef.
The smaller, purer Brothers island: pristine soft-coral walls on every face and a northern plateau where threshers and grey reef sharks gather.

You do not arrange a permit yourself. Access is restricted to licensed liveaboard operators that hold the marine-park permits, and individual divers cannot reach the islands independently. In practice you book a boat on a Brothers or BDE itinerary and the permit is included in the trip cost. There is no shore base, no day boat and no way to dive the islands without a liveaboard.
Enough to be genuinely comfortable in deep, current-swept water. The marine park sets a minimum experience bar, and operators expect Advanced Open Water or equivalent plus a solid logged-dive history with real drift experience. The exact number varies between operators, so confirm with your boat. These are sheer walls with strong current and no shallow refuge, not a place to log your first deep dives.
Yes, for experienced divers who follow the briefing. Oceanic whitetips are curious and approach close, but documented problems trace mostly to diver and guide error rather than the sharks. The discipline is to stay grouped, keep off the open surface, hold the shark in view and avoid flashy movement. Most regulars say the bigger real risk is the current sweeping a lone diver off the island, which is why solo blue-water excursions are discouraged.
They are usually dived together on the BDE safari, so it is rarely either-or. The Brothers are the most varied of the three, the only stop with wrecks alongside the shark walls. Daedalus is the big hammerhead and anemone-city reef further south, and Elphinstone is the single famous offshore pinnacle closest to the coast. If wrecks matter to you, the Brothers are the differentiator; for pure reef-and-shark, the other two are very similar in character.
October and November are the widely cited sweet spot, with clear water, reliable oceanic whitetips, calmer seas and fewer boats than midsummer. May to October is the window for hammerhead schools and the warmest water. January and February bring rougher crossings and a higher chance that exposed Little Brother is dropped from the itinerary. The season runs roughly spring through autumn, weather permitting.
No. The islands sit roughly 67 km offshore, around a 7 to 9 hour open-sea crossing from Hurghada, so there is no day-boat option. Every dive is run from a liveaboard, and since 2018 the boats cannot even moor overnight at the islands; they arrive, dive through the day and leave in the afternoon. A Brothers trip is a multi-night safari, typically five to seven nights, or longer on a combined route.
Oceanic whitetips are the headline and the most reliable, present year-round and most often seen out in the blue off the walls. Scalloped hammerheads school in summer, best off Little Brother's north plateau, and threshers rise to the dawn cleaning stations in the cooler months. Grey reef and silvertip sharks work the walls and plateaus through the year. No single dive guarantees them, but the Brothers are among the most consistent shark diving anywhere.
A 2018 marine-park directive ended overnight mooring at the islands to ease pressure on the site, so boats now arrive, dive through the day and leave in the afternoon rather than staying put. Some regulars feel the change has thinned the shark action that a constant overnight presence used to bring, while others still report the full pelagic roster. Either way, it shapes the rhythm of a Brothers day.
It varies from flat calm to genuinely rough. The passage from Hurghada is 7 to 9 hours of open sea, usually sailed overnight to arrive at first light, and wind can build a short, steep chop. Seasickness medication is worth taking. Once on site, rough mornings can ground the zodiacs and force dives straight off the moored boat instead of the plateau you hoped for, so weather shapes the diving as much as the marine life.
