Elphinstone is a 300 m submerged ridge off the Egyptian coast near Marsa Alam, and it is an advanced drift dive. It rises from deep water to within a few metres of the surface, and the best diving is on the plateaus at its northern and southern tips.
The reputation rests on two things: the walls, and the oceanic whitetip sharks that patrol the blue water off the tips. From October to December, when the whitetips are most reliably present, the shark odds are at their best.
What makes Elphinstone different
Most Red Sea reefs sit in shallow water with easy mooring and manageable conditions. Elphinstone is an offshore reef in open water, exposed to current and swell, and it drops straight to depth on both sides. The walls run from the surface to over 70 m, with no gradual slope and no sandy bottom to check your depth against. Below you there is only open blue.
That is why you need to manage your descents and ascents well here. You have the reef on one side, the open ocean on the other, and the knowledge that anything could come out of the blue. On good days it does.
Soft coral covers both walls. Sea fans reach arm-length and gorgonians cover every overhang. The fish life is layered: anthias in the shallows, grouper mid-water, and tuna, barracuda and jacks hunting in the current off the tips.
The two plateaus
Elphinstone is dived at two entry points, and each has its own character.
North plateau
The northern tip is the access point for most liveaboards. The plateau sits at 18–25 m and widens into a fin-shaped shelf before dropping off on both sides. You spend your shallower time here, working the plateau and watching the fish life, before moving to the western wall.
The western wall holds the densest soft coral. Work along it with the gentle current, within your depth limit and your guide's plan. Visibility is typically 20–25 m, and often more in winter. From October to December this is also where the oceanic whitetips come in from the blue.
South plateau
The southern tip runs deeper and gets fewer divers. The plateau starts at around 28 m, close to the 30 m limit for Advanced Open Water, and the walls plunge quickly. Hammerheads have been spotted at depth off the southern tip, particularly early in the morning on an incoming current, the same pattern as Brothers Islands.
The south is the more demanding drift of the two. The current is less predictable and conditions change faster, so most operators save it for experienced groups and run the north as the standard dive. If your guide offers the south, take it only if it stays inside your certification and your experience.
Oceanic whitetips: what to expect
Oceanic whitetips (Carcharhinus longimanus) are the reason serious divers come from October to December. They arrive with the cooling water and stay through the winter. The IUCN Shark Specialist Group's Elphinstone Reef factsheet reports that encounter rates peak in October and November. It calls these the largest known aggregations of oceanic whitetips in the Red Sea, with up to 28 sharks together.
They are not reef sharks, and they do not circle. They approach, often directly, with the slow confidence of an open-ocean predator, and they are inquisitive. Experienced divers handle this well. Nervous divers do not. Brief honestly before you get in.
- Stay in a close group, especially if you leave the reef and head into open water or near the surface.
- Keep movements calm. Flashy gear, erratic arm movements and skin reflecting the sun can pull a shark in closer for a look. Panicked fin-kicking, a fast ascent or splashing can trigger a more intense investigation.
- Hold your position and let the shark decide the interaction.
- Never touch, ride or chase a shark, and keep your distance. Egypt's Environment Ministry guidance, reported by Egyptian Streets in 2016, is at least 3 to 4 m from an oceanic whitetip. Your guide's briefing sets the rule for the dive.
A good operator and guide understand shark etiquette and stress it in the briefing. If yours does not mention it before an Elphinstone dive in peak season, that is a flag.
When to dive Elphinstone
October to December is the window for whitetips, and summer is the time to avoid if Elphinstone is the point of your trip.
| Months | What to expect |
|---|---|
| October to December | The main window. Whitetips are present and hammerheads at depth are most reliable. The water cools from about 27–28 °C in October to 24–25 °C in December, and visibility is at its best, 25 m or more on good days |
| January to March | Still excellent. Whitetips can still be present, and hammerheads at depth are still most reliable in January, then less so. The reef is fully active. Water drops to about 22 °C, and a 5 mm suit is appropriate |
| April to May | A transition: good diving and drift conditions, with less shark activity |
| June to September | Warm water, 28 °C and above, and competent diving, but the pelagic activity that makes Elphinstone special thins out |
How to dive Elphinstone
Elphinstone is liveaboard territory. The reef is about 15 km offshore from Marsa Alam and a natural stop on a southern Red Sea itinerary.
Most south Red Sea liveaboards run 7 nights and include Elphinstone alongside Brothers Islands, Daedalus Reef and the St John's and Rocky Island area.
Day trips from Marsa Alam exist but depend on the weather and are limited to one or two dives. To dive both plateaus, take the dawn dives and give yourself the best chance of a whitetip, a liveaboard is the only sensible option.

Who can dive Elphinstone
Elphinstone is not a beginner site. The minimum:
- Advanced Open Water certification. Depth, navigation and buoyancy skills are all tested here.
- Comfort in open-water drift conditions. You may be in blue water with no visual reference below you.
- 30–50 dives minimum, and ideally some current experience before you arrive.
- Calm under pressure. That is not a personality judgement. It is a safety consideration, given the shark behaviour at this site.
Divers who meet these criteria will have a great dive. Divers who do not will have a stressful one. Stay inside your certification depth: 30 m for Advanced Open Water (PADI).
The surface can also get choppy, so be comfortable there and get your head underwater quickly. Book a comfortable boat too: start with the best Red Sea liveaboards.
Elphinstone, Brothers and Daedalus
Serious Red Sea divers build south itineraries around these three sites, and each has a different character.
| Site | Character | Known for |
|---|---|---|
| Brothers Islands | The most dramatic of the three | Two small islands with walls, the wrecks Numidia and Aida, and whitetip encounters |
| Elphinstone | The pure drift and shark dive | Less dramatic scenery than Brothers, but often better current action |
| Daedalus Reef | The most remote and the least visited | Hammerheads in numbers that can reach schooling behaviour |
A south itinerary that hits all three gives you three distinct dives. Do not let an operator sell you a "south itinerary" that skips one of them.

Questions
Are there really oceanic whitetip sharks at Elphinstone?
Yes, reliably from October to December, and sometimes as early as September or as late as February, depending on water temperature. The cool, nutrient-rich upwellings around the offshore plateau draw them in. In peak season encounters are common, and several sharks on one dive is not unusual.
How dangerous is Elphinstone reef diving?
Elphinstone is an advanced site with real conditions: strong current, deep water, an offshore location and large sharks. The risk is manageable if you dive within your training and follow your guide's briefing.
The risks are current-related for inexperienced divers and complacency-related for experienced ones. Book with a reliable liveaboard and research your operator first.
Is Elphinstone better than Brothers Islands?
Different, not better or worse. Brothers has the wrecks, the dramatic island scenery and, arguably, the most intense whitetip encounters in the south. Elphinstone has cleaner drift conditions, two distinct plateau dives and sometimes better visibility. Most south liveaboard itineraries include both sites.
What certifications do I need to dive Elphinstone?
Advanced Open Water as a minimum, with a depth limit of 30 m. The depth, current and blue-water conditions exceed what Open Water certification prepares you for.
It is not only about the certificate. Can you hold your depth, get under quickly without wasting time at the surface, control your ascent and dive a full 60 minutes? Surfacing earlier than everyone else becomes challenging when oceanics are circling.
