Diving atThe Blue Hole (Egypt)
Egypt's Blue Hole became a prominent diving destination after the Israeli occupation of the Sinai Peninsula ended in 1979. Its diving history began in 1968, when Alex Shell led a group of Israeli divers in the first exploration of the hole with modern scuba gear. During their pioneering dive, they located the site's most distinctive feature: an underwater arch.
Early observations for The Blue Hole report a surface air temperature of 31.5°C. The water surface is currently presenting wave heights of 0.4 m. Consider these environmental metrics before beginning your descent.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
This iconic submarine sinkhole presents a distinct topography, featuring a maximum depth within the hole of just over 100 m (330 ft). A shallow opening, approximately 6 m (20 ft) deep, connects the hole to the open sea; this area is known as "the saddle." Below this, at a ceiling depth of 55 m (180 ft), lies "the Arch," a 26 m (85 ft) long tunnel.
While the interior offers limited visual interest for recreational divers beyond its seemingly bottomless depths, the vibrant outer reef walls, stretching both north and south, provide extensive exploration opportunities. Many recreational divers opt for the popular Bells to Blue Hole drift dive, starting from a shore entry point north of the main hole. Divers descend a natural chute known as "the Bells," then follow the reef wall, typically ascending as they progress south.
This profile concludes by crossing the coral saddle at 7 m (23 ft) and entering the Blue Hole itself for safety stops. Technical divers, however, often descend directly into the Blue Hole, crossing through the Arch at depths around 56 m (184 ft) to venture into the dramatic blue beyond, where the reef wall plunges far deeper toward the seabed.

Best Time to Dive
Visiting the Blue Hole is possible throughout the year, with various seasons offering different conditions. The shoulder seasons, generally from March to May and September to November, are often recommended; air temperatures are more comfortable during these periods, and dive site crowding tends to be less. During the cooler months of January and February, air temperatures average around 19°C (66°F), while the summer months of July and August can see averages soar to 35-36°C (95-97°F). Rainfall across the year is consistently minimal, with most months reporting less than 0.5 mm, ensuring dry conditions. While average wave heights can reach up to 0.7m (2.3 ft) on the outer reef, the Blue Hole itself is largely sheltered by its outer reef wall, resulting in currents and waves that range from mild to non-existent within the hole.

Dive Experience & Conditions
The dive site's varied depth profile caters to a broad range of certified divers, from recreational to advanced technical. For recreational divers holding an Advanced Open Water certification (allowing dives to 30 m / 100 ft) or CMAS**, the primary experience involves wall diving along the outer reef, often accessed via the Bells entry point. This route typically involves a descent into a chute, followed by a drift along the reef face, culminating in a shallower crossing over the 7 m (23 ft) coral saddle back into the Blue Hole for a safety stop. Technical divers, possessing TDI Extended Range or CCR Mixed Gas certifications, typically initiate their descent within the Blue Hole itself. Their objective often involves crossing the Arch at approximately 56 m (184 ft) into the deeper blue, with options to explore further at depths of 65 m (213 ft), 75 m (246 ft), 90 m (295 ft) or more, extending along the seabed or the northern and southern plateaus. Visibility in the area consistently maintains good levels.
Dive Difficulty & Safety Guidelines
Diving at the Blue Hole necessitates strict adherence to safety protocols and appropriate certification due to its reputation for diver fatalities. Recreational divers must hold a minimum of Advanced Open Water (AOW) or CMAS** certification, allowing dives to a maximum recreational depth of 30 m (100 ft). Prior to any dive at the Blue Hole, local dive centers mandate a check-dive on their house reef. For technical exploration, especially ventures through the Arch or into deeper sections, a minimum of TDI Extended Range or TDI CCR Mixed Gas certification is required, along with a mandatory technical check-dive. All divers must respect the site's operating hours; access to the water begins at 8 AM, and everyone must exit the water and depart the area before 4 PM.

Marine Life at The Blue Hole
Beyond its striking geological formations, the Blue Hole and its surrounding reefs host a rich array of marine organisms. Within the reef structure, divers commonly encounter various invertebrates like boxer shrimp, nudibranchs, and octopus. The vibrant coral gardens are home to diverse fish populations, including clouds of orange and purple anthias and colorful schools of parrotfish. Out in the open water along the outer reef, there's always a chance to spot larger pelagic species; whale sharks, dolphins, eagle rays, and tuna have all been observed here. Reports also indicate sightings of unique species such as the Mola Mola at deeper technical diving depths.
