Where we dived

Dive Site

The Blue Hole is one of Dahab’s most famous dive sites and one of the most recognisable underwater features in the Red Sea. This natural sinkhole drops to around 130 metres, with sheer reef walls surrounding the deep blue water. The site can be approached through the narrow Bells chimney before following the outer reef wall towards the Blue Hole itself, with coral-covered overhangs and abundant Red Sea marine life along the way.

For recreational divers, the Blue Hole offers several ways to explore the site without entering its deepest sections. The famous Arch, however, is a very different proposition: the underwater tunnel connects the Blue Hole with the open sea at around 56 metres and is primarily associated with technical diving. The combination of the dramatic sinkhole, vertical walls and legendary Arch has made the Blue Hole an important destination for both recreational and technical divers.

Diving is possible year-round, but the optimal periods are between March and June and September to November, when water temperatures range from 22°C to 28°C. During these months, visibility is at its peak, and weather conditions are most favorable for diving.

Meet the Locals

Wildlife

  • The Blue Hole is home to typical Red Sea reef life, with clouds of anthias and schools of colourful reef fish around the coral-covered walls. Butterflyfish, angelfish, parrotfish, groupers and lionfish are among the species you may encounter, while moray eels and octopuses hide among the reef formations. Look into the blue and you may spot trevallies, barracuda or an occasional turtle passing along the wall. Eagle rays and reef sharks are possible but not regular sightings, while larger pelagic species have also been recorded around the outer reef. As always, these encounters are never guaranteed on a particular dive.
