Elphinstone Reef

What is Elphinstone Reef?

Elphinstone is an isolated offshore reef shaped like a narrow blade, roughly 300 metres long, whose walls drop steeply into deep water on both its eastern and western sides. Its top sits just below the surface, so waves break over it in rough weather, and at each end it extends into an underwater plateau.

Because it stands alone in the current, it collects life: the walls are covered in soft corals in red, orange and purple, gorgonian sea fans grow on the deeper sections, and schools of barracuda, jacks and tuna patrol the blue. It is one of the most celebrated dives on the mainland coast, and it is the reason many divers choose Marsa Alam over the resorts further north.

The oceanic whitetip sharks

Elphinstone's fame rests on oceanic whitetip sharks, open-ocean predators that visit the reef most reliably from about October to December, though they can be seen at other times. They are bold and curious, and they often approach divers near the surface, which makes for extraordinary encounters and also demands discipline.

Follow the briefing to the letter. Operators typically ask divers to descend quickly, avoid floating at the surface, stay close to the reef and other divers, keep shiny objects and dangling equipment tucked away, and get out of the water promptly at the end. Grey reef sharks, silky sharks and, on some summer dives, scalloped hammerheads off the northern plateau add to the list. Shark behaviour and the rules around it are taken seriously in Egypt after incidents elsewhere on the coast, and conditions can lead operators to restrict or cancel dives.

The dives: north and south plateaus

Dives usually start at either the northern or southern plateau and drift along one wall, with the current deciding which way you go.

• Northern plateau: a sloping shelf from about 20 metres into deeper water, where sharks, including hammerheads in some summer months, patrol the drop-off.
• Southern plateau: a broader shelf with coral heads and fans; deep below it lies a well-known arch, at a depth beyond recreational limits, which you should not attempt.
• The walls: on calm days you can drift the length of the east or west wall in soft coral and blue water, ascending slowly along the reef.

Most day boats do two dives with a surface interval on board. Plan your depth and gas carefully: the blue water and the walls make depth easy to underestimate.

Who can dive Elphinstone?

Elphinstone is for experienced, certified divers who are comfortable with currents, deep walls, blue-water descents and sharks; it is not a place to learn. Most operators ask for an Advanced Open Water certification or equivalent and a minimum number of logged dives, and some also want a recent check dive. Requirements vary, so check with your dive centre.

If you are newly certified, spend a few days on the sheltered house reefs and at Abu Dabbab first, and build your log. Snorkelling at Elphinstone is generally discouraged because of surface conditions and the shark behaviour described above. Our scuba diving in Egypt guide explains courses and certifications, and you should confirm your travel insurance covers diving to the depth you plan.

Getting there: day boat or liveaboard

Day boats reach Elphinstone from harbours around Marsa Alam in roughly 20 minutes to an hour, and the reef is also a regular stop on southern liveaboard routes. Zodiacs are often used for the drop-in, so be ready for a backward-roll entry and a fast descent.

Liveaboards from Port Ghalib often visit Elphinstone at the start or end of a week that includes the Brothers Islands and Daedalus, which gives you early-morning dives before the day boats arrive. Our Red Sea liveaboards guide compares the routes. Diving is weather-dependent, so build a spare day into your stay.

When to go and practical tips

Autumn, roughly October to December, is the best time for oceanic whitetips, with water still about 25–27°C; spring and summer bring calmer seas and the chance of hammerheads on the northern plateau. Winter water drops to about 22–23°C and the northerly wind can make the crossing rough.

• Bring or rent a 5 mm wetsuit in winter and a 3 mm in summer.
• Carry a surface marker buoy and know how to deploy it; it is standard here.
• Avoid diving in the 18–24 hours before you fly.
• Take seasickness precautions: the reef is in open water.
