This dive site, the Blue Hole Dahab, is a legendary vertical underwater sinkhole located just a few miles north of Dahab, Egypt. Plunging to a maximum depth of 120 meters (394 feet), it is globally recognized as both one of the Red Sea's most popular and most dangerous dive sites. Divers typically explore the vibrant coral-covered rim, or for highly experienced technical divers, navigate the infamous Arch at approximately 56 meters, which leads to the open sea. Its unique geological formation and tragic history of diving accidents have earned it a formidable reputation.
The shallow areas of the Blue Hole's rim are home to a diverse array of marine life. Snorkelers and divers can observe a good variety of hard and soft corals, forming beautiful underwater gardens. Common reef fish such as butterflyfish, angelfish, groupers, and triggerfish are frequently encountered. While not primarily known for large pelagics, the open waters surrounding the hole occasionally host transient larger species.
The Blue Hole is best enjoyed during the cooler months from September to May, offering optimal conditions, though diving is possible year-round. It is imperative that divers attempting to explore the deeper sections possess advanced or technical certifications and extensive experience due to the inherent dangers of extreme depth and potential for narcosis or decompression sickness. Freedivers find the Blue Hole an unparalleled site for depth training, while snorkelers can safely and enjoyably explore the rich coral life along its accessible shallow edges.
