Top 10 Reefs in Egypt
Egypt's Red Sea reefs are among the most biodiverse in the world, benefiting from water temperatures that range from just warm enough to support coral in winter to the upper limit of coral tolerance in summer. The Red Sea's relative isolation — a semi-enclosed sea with one narrow connection to the Indian Ocean — has produced a high proportion of endemic species found nowhere else. A well-developed liveaboard industry accesses the remote north and south; shore diving from Dahab, Hurghada, and Marsa Alam gives immediate access to reefs from the beach. All sites are on the interactive map.
1. Ras Mohammed National Park, South Sinai
Ras Mohammed is the southern tip of the Sinai Peninsula where the Gulf of Suez and Gulf of Aqaba meet, creating a confluence of nutrient-rich currents. A national park since 1983, it protects the reef systems of Shark Reef and Jolanda Reef — where the cargo vessel Jolanda once sat before sliding down the wall — and the extraordinary fish density of Shark Reef's northern face. Schools of thousands of fish, including Arabian batfish Platax orbicularis, jacks Caranx sp., and barracuda Sphyraena qenie, aggregate on the walls. Best season: March to May, September to November.
2. Brothers Islands (El Akhawein), Egypt Red Sea
Big Brother and Little Brother are twin oceanic pinnacles rising from 800 metres in the open Red Sea, accessible only by liveaboard. Big Brother has a British lighthouse and two accessible wrecks — the Numidia and the Aida — draped in soft coral and gorgonians. Both islands are surrounded by walls with exceptional large fish encounters: oceanic whitetip sharks Carcharhinus longimanus, grey reef sharks, and thresher sharks Alopias sp. at depth. Among the most demanding and rewarding sites in the Red Sea. Best season: April to October.
3. Daedalus Reef, Egypt Red Sea
Daedalus is an isolated reef 80 kilometres off the Egyptian coast, marked by a lighthouse and surrounded by deep water on all sides. The northern face is exposed to open ocean and consistently produces encounters with oceanic whitetip sharks, hammerheads, and occasionally whale sharks Rhincodon typus. The fish density on the reef walls — massive Napoleon wrasse Cheilinus undulatus, dense grouper populations, and schooling snapper — reflects the site's protection from fishing pressure. Liveaboard only. Best season: May to September.
4. Elphinstone Reef, Marsa Alam
Elphinstone is an oblong reef 50 kilometres off Marsa Alam with a vertical wall on all sides dropping to over 70 metres. Its northern plateau is one of the most reliable sites in the Red Sea for encounters with scalloped hammerhead sharks Sphyrna lewini, which appear — usually in the first hour of the first dive — in the blue water off the north end. Oceanic whitetip sharks patrol the outer wall. The reef top is densely colonised by hard corals. Best season: September to January for hammerheads.
5. Tiran Strait, South Sinai
The Strait of Tiran between the Sinai Peninsula and Saudi Arabia contains four named reef systems — Jackson, Thomas, Woodhouse, and Gordon — that intercept strong tidal currents pushing between the Red Sea and the Gulf of Aqaba. Jackson and Thomas reefs are the most visited; the wreck of the Loullia sits on Jackson's eastern tip. Strong currents require drift diving techniques and produce exceptional fish aggregations. Spinner dolphins Stenella longirostris frequently transit the strait. Best season: March to June.
6. Shaab Rumi, Sudan (accessible from Egypt liveaboards)
Shaab Rumi is technically in Sudanese waters but is visited by liveaboards departing from Port Sudan that also serve Egyptian itineraries. Jacques Cousteau chose Shaab Rumi for his 1963 Conshelf II experiment; the remains of his underwater habitat are still visible at twenty-two metres. Grey reef sharks and hammerheads are present year-round, and the outer wall has some of the finest large gorgonian growth in the Red Sea. Best season: November to May.
7. St John's Reef, Egypt Southern Red Sea
St John's Reef complex in the far south of Egyptian waters, accessible by liveaboard from Marsa Alam, is among the most pristine reef systems in the country. Its distance from major population centres has limited fishing and dive pressure. The reef includes cathedral-like coral structures, healthy hard coral cover, and populations of dugong Dugong dugon — extremely rare at Red Sea dive sites. Napoleon wrasse Cheilinus undulatus are resident on several pinnacles. Best season: October to May.
8. Blue Hole, Dahab
The Blue Hole is a sinkhole 130 metres deep in a fringing reef just north of Dahab. The entry is directly from the beach. Its reputation among the global diving community rests on a combination of extraordinary beauty — the blue light penetrating the hole and the archway at sixty metres connecting to the open sea — and a death toll that makes it one of the world's most dangerous dive sites when approached without appropriate training. Recreational divers should restrict themselves to the reef rim and the coral garden; the arch at sixty metres is a technical dive. Best season: Year-round for reef rim.
9. Marsa Alam Dolphin Houses
The "Dolphin Houses" at Marsa Abu Dabbab near Marsa Alam are shallow inshore reef and seagrass sites where resident pods of Indo-Pacific bottlenose dolphins Tursiops aduncus and the occasional dugong Dugong dugon are seen year-round. The seagrass beds behind the reef support green turtles Chelonia mydas. The combination of megafauna — dolphin, dugong, turtle — on a single site accessible by shore entry makes it exceptional in the Red Sea context. Best season: Year-round.
10. Hurghada Coast Reefs
The reefs immediately off Hurghada — including Giftun Islands National Park — have been heavily visited for decades and show the mixed condition that comes with high diver traffic and historical anchor damage. However, mooring buoy programmes and expanding no-take zones within the park have allowed significant recovery in several sections. Giftun South has good hard coral cover and regular turtle, dolphin, and reef shark encounters. The site's proximity to Hurghada airport makes it the most logistically accessible serious reef diving in Egypt. Best season: April to November.
