Elphinstone Reef - The Red Sea Shark Dive

Elphinstone is not a fringing reef you can swim back to shore from. It is a solitary plateau standing in open water, roughly 300 m long by 30 m wide, aligned north to south so the prevailing current runs the length of it. The top of the reef sits at 5 to 8 m. Both flanks drop away immediately as vertical walls that pass 70 m and keep going, hung with soft-coral curtains, gorgonian fans and clouds of anthias and fusiliers.

Each end has a plateau that shelves out before the drop. The south plateau, at around 20 to 30 m, is the usual first dive and the classic oceanic whitetip station. The north plateau, deeper at 25 to 40 m, is where scalloped hammerheads school in summer. Below the southern tip lies the famous arch at 55 to 80 m - a genuinely technical dive that we do not include in a recreational day trip, whatever anyone else offers. Everything we dive stays inside recreational limits.

This is an advanced site and we book it as one. The minimum is Advanced Open Water (or equivalent) with at least 30 logged dives, of which several should be real drift dives in current and dives to 30 m. You need reliable buoyancy control in mid-water with no reference, comfort in deep blue with the bottom out of sight, the ability to deploy your own SMB, and enough air discipline to hold a group profile. If you have been diving within the last six months, all the better; if not, tell us and we will put you on a check dive first.

It is not the site for a first sea dive after a course, for anyone still task-loaded by their own gear, or for divers who get uneasy when the blue goes dark below them. If Elphinstone is your goal for the trip, the honest route is to build up to it: two or three days on the bays and house reefs first, then Elphinstone with your buoyancy dialled in. We would rather move you to a better-suited site than watch you spend the dive fighting it - and we do turn people away at the briefing when the logbook does not match the conditions that day.

Oceanic whitetip (Carcharhinus longimanus) is the one Elphinstone is famous for. These are open-ocean sharks that come in close to the reef from roughly October to December, peaking around the full moon in November; they are curious, unhurried and often circle a group at a few metres for a whole safety stop. Scalloped hammerheads school off the north plateau in summer, June to September, usually deeper and early in the morning. Grey reef and whitetip reef sharks are resident year-round, and silvertips turn up regularly along the walls.

None of this is baited, fed or chummed - it is illegal in the Egyptian marine park and it changes shark behaviour permanently. That means encounters are genuinely wild: some days the blue is empty and you dive a spectacular soft-coral wall instead. Across a season roughly two dives in three at Elphinstone produce a shark of some species, and the whitetip window in late autumn is far better than that. We also brief you on how to behave around an oceanic whitetip - stay in the group, stay vertical in mid-water, keep eye contact, no chasing, no touching, do not swim off alone at the surface.

The current at Elphinstone runs mostly north to south and can be strong, and it splits around the reef so both walls and the plateau tips behave differently on the same day. Our guides read it at the surface before anyone kits up, and the plan follows the water: sometimes a negative entry straight to the plateau and a drift, sometimes a sheltered wall on the lee side, occasionally a decision that the day is not diveable at all. Nobody gets talked into an entry that does not look right.

Practically: groups are capped at 4 divers per guide, everybody carries an SMB and a whistle, and the speedboat stays with the group and picks divers up wherever they surface, which is why drift profiles are safe here. We plan conservative profiles with a full safety stop, and nitrox 32% is available for an extra fee - strongly recommended, since it buys meaningful bottom time on the deeper plateau. If the forecast turns, we move the trip to another day or refund it rather than run it in bad water.

Elphinstone is a fast half-day, not a boat safari. We pick you up between Port Ghalib, Marsa Alam town and El Quseir, drive you to the speedboat launch point on the north coast, and check certification cards and logbooks before boarding. The full briefing happens before the crossing, so the 45 minutes of open water is decompression time for your head rather than a scramble. Two guided dives follow, with a surface interval on board over water and snacks.

The whole thing is about five hours door to door and you are back at the hotel for lunch, which is why so many guests pair Elphinstone with a relaxed shore dive the next morning. Bring your certification card and logbook - we do check them - plus a wetsuit appropriate for 22 to 29°C water, and your own computer if you have one. Rental equipment is available at extra cost.

The reef is diveable year-round, and the season you pick decides what you are likely to meet. October to December is oceanic whitetip season and the reason most people come; November is the peak. June to September brings the summer hammerhead schools on the north plateau and the warmest water at 28 to 29°C. Spring, March to May, is the quietest for sharks but the best for visibility and the odd reef manta, and the walls are at their most colourful.

Water runs from about 22°C in February to 29°C in August; a 5 mm wetsuit is right for winter and a 3 mm for summer. Wind is the real constraint rather than season: Elphinstone sits in open water and a stiff northerly shuts it down at any time of year, which is why we always keep a sheltered alternative site in reserve. Book two to three days ahead in high season, and if the whitetips are your goal, give yourself more than one shot at the reef rather than a single day.
