Blue Hole (Red Sea)
The Blue Hole is a renowned diving site located on the coast of the Gulf of Aqaba in Egypt's Red Sea. It is a deep marine sinkhole, famous for its challenging "Arch" tunnel and notorious for being the site of numerous diver fatalities, earning it the grim distinction of having the highest number of diver deaths globally. Despite its dangers, the Blue Hole remains a popular destination for experienced divers and freedivers due to its direct shore access to significant depths and abundant marine life.

About Blue Hole (Red Sea)
The Blue Hole (Red Sea)
The Blue Hole is a globally recognized, yet notoriously perilous, diving location situated on the southeastern coast of the Sinai Peninsula in Egypt, along the Gulf of Aqaba. This deep marine sinkhole is renowned for its dramatic underwater topography, including a challenging tunnel known as "the Arch," and its abundant marine life.
Geological Significance and Features
Geologically classified as a blue hole, the site plunges to depths exceeding 100 meters (330 ft). A notable feature is "the Arch," an underwater tunnel approximately 26 meters (85 ft) long, with its ceiling at a depth of 55 meters (180 ft). The surrounding waters teem with diverse coral formations and a variety of reef fish, making it visually spectacular for divers and snorkelers. A shallow opening to the sea, called "the saddle," is located around 6 meters (20 ft) deep.
Diving History and Dangers
The Blue Hole gained international attention as a dive site during the Israeli occupation of the Sinai Peninsula, with Israeli divers first exploring it with modern scuba equipment in 1968. Since 1982, it has become a very busy dive location. However, its fame is heavily shadowed by its reputation as the site with the highest number of diver fatalities worldwide. While the Blue Hole itself is not inherently more dangerous than other Red Sea dive sites, the extreme nature of diving through "the Arch"—requiring advanced technical training, precise gas management, and competence in overhead environments—has led to numerous accidents.
Factors contributing to the high fatality rate include the site's notoriety attracting less experienced divers seeking a challenge, the deceptive clarity and warmth of the water masking the inherent risks, the difficulty in locating the Arch's entrance, underestimation of the tunnel's length and current, and the significant gas consumption and decompression requirements at depth. Nitrogen narcosis at these depths can also impair judgment, leading to critical errors. The tragic death of Yuri Lipski in 2000, captured on video, is one of the most well-known incidents and highlights the extreme dangers involved.
Safety and Accessibility
In response to the high number of accidents, safety measures have been implemented. The Egyptian Chamber for Diving and Watersports now stations a policeman at the site to ensure divers are accompanied by certified guides. While recreational divers can access parts of the Blue Hole, local operations typically limit them to 30 meters, with passage through "the Arch" reserved for highly qualified technical divers. Despite the risks, its unique accessibility from shore to significant depths continues to draw divers and freedivers.
