Home to four major reefs—Jackson, Woodhouse, Thomas, and Gordon—this area is known for strong currents, pelagic fish, and colorful coral.

Southern Red Sea Gems

4. Daedalus Reef

Accessible only by liveaboard, Daedalus is home to schooling hammerheads, steep walls, and vibrant coral.

5. Brothers Islands

Advanced divers flock to this remote site for sightings of oceanic whitetips, thresher sharks, and even manta rays.

What Can You Expect to See While Diving in the Red Sea?

Hurghada Private Snorkeling -Top Class Egypt Travel

One of the most exciting things about diving in the Red Sea is the sheer variety and abundance of marine life. Whether you love spotting majestic sharks, photographing microscopic critters, or simply floating through colorful coral gardens, the Red Sea offers unforgettable underwater encounters at every turn.

Let’s take a closer look at the marine wonders you’re likely to meet beneath the surface:

Sharks Galore

The Red Sea is one of the best places in the world to see sharks in their natural habitat.

  • Hammerhead Sharks: Found around Daedalus and Brothers Islands, these schooling predators are often seen cruising in the blue.

  • Oceanic Whitetip Sharks: Frequently spotted at Elphinstone Reef and Big Brother Island, these are bold, curious sharks known for circling divers.

  • Grey Reef Sharks and Threshers: Common around the deep southern reefs.

  • Occasional sightings: Tiger sharks and silky sharks are rare but possible in deeper waters.

Shark sightings are especially common during the summer months when the water is warmer.

Sea Turtles

You’re almost guaranteed to see green or hawksbill turtles leisurely gliding past the reefs or resting on coral shelves. These gentle giants are frequently spotted around Marsa Alam, Ras Mohammed, and Tiran Island.

Playful Dolphins

Several species of dolphins call the Red Sea home. You might see:

  • Spinner dolphins: Often travel in pods and are known for their acrobatics.

  • Bottlenose dolphins: Found near reefs and even around some liveaboards. Some dive operators offer responsible dolphin snorkeling trips near Sataya Reef (Dolphin House).

Reef Fish in Every Color

The reefs here are a living rainbow of fish and invertebrates. You’ll see:

  • Clownfish nesting in anemones

  • Butterflyfish darting through coral

  • Parrotfish chomping on algae-covered rock

  • Schools of anthias dancing over coral heads

With over 1,200 species of fish, including more than 150 found nowhere else in the world, every dive feels like discovering a new planet.

Macro Marvels for Photographers

If you're into macro photography, the Red Sea won’t disappoint. Peer into coral crevices and sandy bottoms to spot:

  • Nudibranchs in every imaginable color

  • Tiny pipefish camouflaged like twigs

  • Peacock mantis shrimp, boxer crabs, and cleaner shrimp

Photographers will love the excellent visibility and soft lighting, especially on early morning and dusk dives.

Pelagic Encounters

In deeper, offshore sites, divers might see larger, migratory species such as:

  • Manta rays gliding through the currents at Rocky Island or Daedalus

  • Giant trevallies and barracudas schooling in open water

  • Tuna, sailfish, or even whale sharks in the far southern reaches of the Red Sea

 World-Class Coral Reefs

The Red Sea is home to some of the healthiest and most colorful coral reefs in the world, largely unaffected by global bleaching events. Expect to see:

  • Soft and hard coral gardens stretching for miles

  • Towering coral pinnacles and caves

  • Table corals the size of cars

Some of the best coral diversity can be found at Fury Shoals, Sataya, Ras Umm Sid, and St. John’s Reef.

Scuba Diving in Hurghada - Top Class Egypt Travel

Spring (March – May)

Spring is one of the most popular seasons for diving in Egypt, offering warm weather and good visibility.

  • Water temperature: 23–26°C (73–79°F)

  • Air temperature: Pleasant and not too hot yet

  • Visibility: Excellent, often up to 30 meters

  • Water temperature: 26–28°C (79–82°F)

  • Air temperature: Cooler and more comfortable than summer

  • Water temperature: 22–24°C (71–75°F)

  • Air temperature: Mild and perfect for sightseeing between dives

  • Visibility: Excellent

  • Marine life: Turtles, dolphins, and plentiful reef fish, although some pelagics move to warmer waters

It’s a great time for diving in Hurghada, Marsa Alam, and Dahab, particularly if you're combining diving with land-based tours like the pyramids or desert safaris.

Liveaboard Diving vs. Resort Diving: Which One Is Right for You?

Scuba Diving in Hurghada - Top Class Egypt Travel

One of the most common questions when planning a Red Sea diving trip is: Should I stay at a resort or go on a liveaboard? Both options offer amazing experiences, but they cater to different travel styles, budgets, and levels of diving enthusiasm.

Let’s break it down to help you choose the right experience for your underwater adventure.

Liveaboard Diving: Dive, Eat, Sleep, Repeat

Best cairo cruises & boat tours 2025 Top -Class Egypt Travel

A liveaboard is a specially designed dive boat that doubles as a floating hotel. These trips typically last from 3 to 7 nights (or longer), and they take you far away from crowded shores to some of the most pristine and remote dive sites in the Red Sea.

Who is it for?

  • Avid divers looking to maximize dive time

  • Adventure seekers who want to explore remote reefs and islands

  • Underwater photographers in search of rare marine life

  • Certified divers with at least Open Water certification (some sites require Advanced)

Benefits of liveaboard diving:

  •  Access to exclusive dive sites like Daedalus, Elphinstone, Brothers, Rocky, and St. John’s Reef that are too far for day trips

  •  Up to 4-5 dives per day, including early morning and night dives

  •  Less crowded dive spots, often with just your group in the water

  •  All-inclusive packages: diving, meals, accommodation, and dive guides in one price

  •  A tight-knit, social atmosphere with fellow divers onboard

Things to consider:

  •  Space is limited—cabins are comfortable but compact

  • If you get seasick, bring medication (some crossings can be bumpy)

  •  You’ll need to commit several consecutive days to be out at sea

If diving is your main goal, a liveaboard is hands-down the best way to explore the Red Sea.

Resort-Based Diving: Comfort and Flexibility

Top Resorts in Marsa Alam - Top Class Egypt Travel

Resort-based diving is ideal for travelers who want to combine underwater exploration with on-land comfort, sightseeing, and relaxation. You’ll stay in a hotel or dive resort and go on daily dive trips to nearby reefs.

Who is it for?

  • Beginners or those learning to dive

  • Divers traveling with non-diving companions or family

  • Vacationers who want to mix diving with beaches, spa time, or sightseeing

  • Travelers with limited time or a flexible schedule

Benefits of resort diving:

  •  Greater flexibility—you can dive one day, relax the next

  •  Ideal for training courses like PADI Open Water or Advanced

  •  Comfortable accommodations with pools, restaurants, and local excursions

  • Access to famous reefs like Ras Mohammed, Thistlegorm, and local house reefs

  •  Easier access to nightlife, shopping, and cultural tours

Things to consider:

  • Fewer dives per day (usually 2–3 max)

  •  You may need to take boat trips daily to reach dive sites

  •  Popular sites can be crowded during peak seasons

If you prefer a balanced vacation with diving as one part of the experience—or you’re new to diving—a resort-based trip is a great option.

Safety Tips for Red Sea Diving

Scuba Diving in Hurghada - Top Class Egypt Travel

While scuba diving in the Red Sea is generally safe and professionally managed, it’s essential to follow proper safety protocols to ensure a fun, smooth, and risk-free experience—whether you're a beginner or a seasoned diver.

The Red Sea’s crystal-clear visibility, warm waters, and well-established dive infrastructure make it a great choice for divers of all levels. Still, conditions can vary from one site to another, and a bit of preparation goes a long way in keeping your underwater adventure safe and enjoyable.

Here’s what you need to keep in mind:

1. Always Dive with a Certified Dive Center

Choose a dive operator with international certifications such as PADI, SSI, or CMAS. Licensed dive centers follow strict safety protocols and provide:

  • Qualified dive guides and instructors

  • Regularly serviced diving equipment

  • Emergency oxygen and first-aid kits onboard

  • Briefings on dive site conditions and hazards

  • Read reviews or check their safety record before booking your dives.

 2. Inspect Your Gear Carefully

Whether you're renting equipment or bringing your own:

  • Test your BCD and regulator before the dive

  • Check your mask, fins, and weights for proper fit

  • Ensure your dive computer or depth gauge is functioning

  • Always carry a surface marker buoy (SMB)

If you're on a liveaboard, crew members usually assist with setup and double-check your gear, but it's still smart to do your own pre-dive check.

3. Know the Dive Conditions

The Red Sea can offer everything from calm, shallow reefs to deep drift dives with strong currents. Ask about:

  • Water temperature and visibility

  • Depth and topography

  • Current strength and direction

  • Entry/exit points and boat pickup plans

If the dive is too advanced for your comfort level, don’t be afraid to sit it out or request an easier dive. Diving within your limits is key.

 4. Stay Hydrated and Avoid Alcohol

Diving is a physically demanding activity—especially under the sun. Dehydration can increase your risk of decompression sickness (DCS), so:

  • Drink plenty of water before and after diving

  • Avoid alcohol at least 12 hours before your first dive

  • Eat light meals, especially if you’re diving multiple times a day

 5. Stick to the Dive Plan

Always follow the dive briefing and:

  • Stay within recreational dive limits (max 30m/100ft for most certifications)

  • Monitor your air supply and bottom time

  • Ascend slowly and always perform a safety stop at 5 meters (15 feet) for 3–5 minutes

  • Stick with your buddy or group, especially in low-visibility or current-heavy areas

  • Agree on hand signals and emergency procedures with your dive buddy before each dive.

 6. Respect Marine Life and Coral Reefs

The Red Sea’s reefs are a delicate ecosystem. To protect them and yourself:

  • Don’t touch or stand on coral—your fins can damage years of growth

  • Avoid chasing or touching marine life, especially turtles, rays, and sharks

  • Use a reef-safe sunscreen to minimize pollution

  • Never collect souvenirs like shells or coral

7. Be Prepared for Emergencies

Before you dive:

  • Know the location of the nearest hyperbaric chamber (there are several along the Egyptian coast)

  • Make sure your travel insurance covers scuba diving

  • Consider diver-specific insurance like DAN (Divers Alert Network)

  • Keep emergency contact numbers and DAN hotline accessible

If you're doing multiple dives per day or deep dives, take special care with your no-fly time—typically 18 to 24 hours before boarding a plane.

8. Take a Refresher Course if Needed

If you haven’t dived in over 6–12 months, it’s highly recommended to take a refresher course or do a check dive with an instructor. This helps:

  • Regain comfort with buoyancy control

  • Practice emergency procedures

  • Familiarize yourself with local conditions

 9. Log Your Dives and Debrief

After each dive:

  • Log your dive time, depth, and air usage

  • Note marine life sightings and conditions

  • Talk with your dive buddy about what went well and what could be improved

This helps you become a better, safer diver over time—and it’s fun to track your experiences.

Diving in the Red Sea is an incredible experience, but just like any adventure, it requires awareness and responsibility. Follow these tips and you’ll enjoy a safe, spectacular journey through one of the world’s most beautiful underwater playgrounds.
