Blue Hole


"Blue Hole"! This place is probably one of the most dangerous dive sites in the world, which magically captivates divers and snorkelers from all over the world and is now considered one of the most visited dive and snorkel sites in the world!


This enormous hole along the coast in the coral reef with a diameter of 50 to 65 meters is located 10 km north of Dahab in the east of the Sinai Peninsula. The steep slopes reach depths of a remarkable 70 to 110 meters.

The Blue Hole is a large hole in the reef roof of the coastal fringing reef, which drops vertically from 70 m to 110 m. It has a diameter of 50 to 65 m.
The reason why the Blue Hole is considered the most dangerous dive site in the world is because of its connection to the open sea, which because of its shape is called "Arch". It extends from the bottom of the Blue Hole up to a depth of 55 m. At its upper end it is only a few meters wide and approx. 26 m long. The reef also forms an almost vertical drop on the outer edge, which continues below the "exit" of the Blue Hole as a steep slope down to several hundred meters.


  • Most dives are made along the outer steep drop of the reef.
  • The “Bells” dive site, which is located about 150 meters from the Blue Hole, usually serves as the entry point.
