Diving the Red Sea: Egypt's Best Sites, Seasons & Liveaboards

Why the Red Sea Is World-Class

The Red Sea is one of those rare destinations that delivers on every front. Warm water year-round (21-30°C), visibility that routinely exceeds 30 metres, over 300 species of coral, 1,200+ fish species, and a concentration of world-class wrecks found nowhere else. For European divers, it's also remarkably accessible - a 5-hour flight from London, with no jet lag. It's no wonder the Red Sea has been a pillar of recreational diving since the sport's earliest days.

The Must-Dive Sites

SS Thistlegorm

The most famous wreck dive on the planet. This 128-metre British merchant navy ship was sunk by German bombers in 1941 while carrying supplies to the Allied forces in North Africa. The cargo holds remain packed with wartime equipment: motorcycles, trucks, rifles, ammunition, railway locomotives, and aircraft wings. Discovered by Jacques Cousteau in 1955, the Thistlegorm lies at 30 metres in the Straits of Gubal and can be dived from Sharm el-Sheikh or Hurghada, either as a day trip or on a liveaboard. The marine life has colonised the wreck extensively - batfish school around the masts, giant morays inhabit the engine room, and tuna patrol the surrounding water.

Ras Mohammed National Park

The southern tip of the Sinai Peninsula where the Gulf of Suez meets the Gulf of Aqaba. The currents converging here create nutrient-rich upwellings that support extraordinary marine life. Shark and Yolanda Reefs - the park's signature dives - feature a pristine coral wall dropping into the abyss, schools of barracuda and jacks in the blue, and the scattered cargo of the sunken freighter Yolanda (including a now-iconic field of toilets at 25 metres). It's dramatic, diverse, and consistently delivers.

Brothers Islands (El Ikhwa)

Two isolated sea pinnacles 60 kilometres offshore in the open Red Sea, accessible only by liveaboard. The Brothers are surrounded by deep water and battered by currents, creating conditions that attract oceanic whitetip sharks, thresher sharks, hammerheads, and mantas. Big Brother has a 19th-century lighthouse and the wrecks of the Aida (an Egyptian supply vessel) and the Numidia (a cargo ship), both encrusted with soft corals. These are advanced dives in challenging conditions - and absolutely worth it.

Elphinstone Reef

A torpedo-shaped reef south of Marsa Alam renowned for oceanic whitetip shark encounters. The north and south plateaux drop away into deep blue water where these open-ocean predators cruise. The reef walls are covered in spectacular soft corals - purples, oranges, and reds that look like underwater gardens. Dolphins are regular visitors. Strong currents are common, making this an intermediate to advanced dive.

Dahab Blue Hole

The Dahab Blue Hole is a 100-metre-deep sinkhole in the reef, accessible from shore. For recreational divers, the main attraction is the shallow reef rim and the short tunnel called "The Bells" that leads through the reef to the Blue Hole's interior. It's an atmospheric, beautiful dive at recreational depths. The Blue Hole's notorious reputation comes from technical divers attempting the deep "Arch" at 56 metres - a dangerous undertaking that has claimed lives. Stay within your limits and the Blue Hole is magical.

Sharm vs Hurghada vs Marsa Alam

Sharm el-Sheikh: The original Red Sea resort. Best access to the Straits of Tiran, Ras Mohammed, and the Thistlegorm. More developed and touristy, with excellent infrastructure.

Hurghada: Larger town, slightly cheaper. Access to Giftun Island reefs, Abu Nuhas wrecks (four shipwrecks on one reef), and northern liveaboard routes.

Marsa Alam: The quieter south. Closer to Elphinstone, Fury Shoals, Samadai Reef (the "Dolphin House"), and the deep south. Better for dugong encounters at Abu Dabbab and sea turtles on seagrass beds. Growing rapidly but still less crowded.

Liveaboard Routes

The Red Sea is one of the world's great liveaboard destinations. The main routes are:

Northern route: Thistlegorm, Ras Mohammed, Straits of Tiran, Abu Nuhas wrecks. Good for all levels.
Brothers, Daedalus & Elphinstone (BDE): The big-animal circuit. Sharks, mantas, and dramatic reefs. Intermediate to advanced.
Deep South: Fury Shoals, St Johns Reef, Rocky Island, Zabargad. Pristine reefs, fewer boats, dolphins, and sharks. Advanced.

When to Go

March-May and September-November offer the best balance of warm water, good visibility, and marine life activity. Summer (June-August) brings the warmest water (28-30°C) but can be windy in the north. Winter (December-February) drops to 21-23°C - a 5mm wetsuit or drysuit may be welcome - but visibility is often at its best and sites are quieter.
